Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration. The example does not become active until you commit the candidate configuration.
Page 12
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
is a full example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
xii
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
Page 13
Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
xiii
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf

PTX10003 System Architecture
24
Using Juniper Networks custom ExpressPlus silicon, the PTX10003 system architecture cleanly separates
control operations from packet forwarding operations. This design eliminates processing and traffic
bottlenecks, permitting the PTX10003 to achieve high performance.
Control operations are performed by the Routing Engine, which runs Junos OS Evolved. The Routing
Engine handles routing protocols, traffic engineering, policy, policing, monitoring, and configuration
management. Junos OS Evolved is pre-installed on the PTX10003 internal solid-state drives (SSDs).
Forwarding operations are performed by the Packet Forwarding Engines (PFE) to deliver inline MACsec
on all ports and high density high density 10 GbE, 40 GbE, 100 GbE, 200 GbE, and 400 GbE.
PTX10003 System Software
The PTX10003 runs Junos OS Evolved, which provides Layer 2 and Layer 3 switching, routing, and security
services. Junos OS Evolved runs natively on Linux, giving it direct access to all the Linux utilities and
operations. It is designed to be modular, allowing for upgrades to be done on a component-by-component

PTX10003-160C Port Panel
Operating in a fixed core router configuration, the PTX10003-160C features flexible interface configuration
options with universal multi-rate double-density Quad Small Form-factor Pluggable (QSFP-DD) optics.
The port panel has 80 optical interfaces which support data rates of 10 Gbps, 25 Gbps, 40 Gbps, 100 Gbps,
200 Gbps, and 400 Gbps. Each of the 16 Juniper Networks 1 Tbps ExpressPlus ASICs in the PTX10003-160C
connect to a group of five QSFP-DD ports. You can configure different data rates for each port group as
long as the total throughput for the group does not exceed 1 Tbps. For more details, see “Understanding
QSFP-DD Interfaces and Configurations” on page 28.

Understanding QSFP-DD Interfaces and Configurations
Each Juniper Networks 1 Tbps ExpressPlus ASIC contains two logically independent PFEs which can
provide 400 Gbps throughput. Each QSFP-DD port group is controlled by two PFEs with the middle
QSFP-DD interface (port 2 and port 7) being shared by the PFEs.
Any port can be used as a 100-Gigabit Ethernet interface, 40-Gigabit Ethernet interface, or 10-Gigabit
Ethernet interface. You choose the speed by plugging in the appropriate optical transceiver. You can also
channelize the 100 Gbps and 200 Gbps ports to create multiple independent 25 Gbps interfaces. You can
channelize the 40 Gbps ports to create multiple independent 10 Gbps ports. See Channelizing Interfaces
on PTX10003 Routers for more details.
Given the design of the Juniper Networks ExpressPlus ASIC and chassis level thermal considerations, there
are certain limitations for some QSFP-DD interfaces and configurations. Each QSFP-DD port group can
be configured to achieve the maximum 1 Tbps throughput with the following limitations:
Page 28
Only the interfaces at the outer edge of each QSFP-DD group can be configured for 1x400 Gbps (using
•
QSFP56-DD optics).
The middle QSFP-DD port that is shared across two PFE’s (port 2 and port 7) cannot support a data rate
•
of 1x200 Gbps. These ports can only support 2x100 Gbps (QSFP28-DD).
The highest QSFP-DD data rate that can be used across all QSFP-DD groups is 200 Gbps (2x100 Gbps).
•
This provides 16 Tbps throughput for the PTX10003-160C, and 8 Tbps throughput for the
PTX10003-80C.
Aside from running all interfaces with 2x100 Gbps optics, there are other ways to attain the maximum
•
system throughput. The 400 Gbps optics can be used in combination with 100 Gbps optics and 200 Gbps
optics as shown in the following examples.
Allowable QSFP-DD Interface Configurations for the PTX10003-160C

Examples of PTX10003 QSFP-DD Configurations
By default, all PTX10003 QSFP-DD interfaces are configured for a data rate of 2x100 Gbps. You can
change the port configuration to achieve different throughput using the following Junos OS Evolved
command:
set chassis fpc slot-number pic pic-number port port-number number-of-subports [1 | 2 | 4 |8] speed [10G
| 25G | 40G | 100G | 200G |400G] command.
For example, to configure the second port in the first port group as a 4x10 Gbps interface, use the set
chassis fpc 0 pic 0 port 1 number-of-subports 4 speed 10g command. After you commit this configuration,
the second port in PIC 0 will operate at 4x10 Gbps.

the default port speed for the transceiver. If you try to configure a port speed that is not supported
by the transceiver, the port will be disabled. If there isn’t a port speed configured on a valid optical
port, the PTX10003 uses a default port speed of 2x100 Gbps. Also, if number-of-subports is not
configured, a 1x 40G | 100G |200G |400G] data rate is assumed. A 1x10G sub-port is not supported.
Example: Using Network Ports as 10 Gbps or 40 Gbps Ethernet Interfaces
With QSFP+ transceivers, you can configure 10 Gbps or 40 Gbps interfaces on any port. To attain the
maximum 1 Tbps throughput for a port group, you can configure the 10 Gbps and 40 Gbps ports with
combinations of 1x100 Gbps, 2x100 Gbps, and 400 Gbps, data rates. Refer to Table 6 on page 31.
31
NOTE: 1x10 Gbps and 2x10 Gbps are not supported.
NOTE: Only the ports at the outer edge of each group can be configured for 1x400 Gbps (using

PTX10003 Port LEDs
Each PTX10003 port uses a single bi-colored LED to indicate link status and activity. See
Table 10 on page 34 for how to interpret the port LEDs.
NOTE: After you insert an optical transceiver, the LINK UP LED flashes red and green during the
first 60 seconds. This means the link is unstable. It may take up to 60 seconds for the LED to stop
flashing.

Channelizing Interfaces on PTX10003 Routers with Junos OS Evolved
PTX10003 Packet Transport Routers feature flexible interface configuration options with universal multi-rate
double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The PTX10003-80C port panel has
40 physical ports and the PTX10003-160C port panel has 80 physical ports. The physical ports are in
groups of five QSFP-DD ports. You can configure different data rates for each port group as long as the
total throughput for the group does not exceed 1 Tbps. Any port can be used as a 100-Gigabit Ethernet
interface, 40-Gigabit Ethernet interface, or 10-Gigabit Ethernet interface. You choose the speed by plugging
in the appropriate transceiver.
NOTE: The center port in each port group (port 2 and port 7) cannot support 1x200 Gbps. To
configure a 200 Gbps data rate for those ports, you’ll need to configure them as 2x100 Gbps. For
more details, see “Understanding QSFP-DD Interfaces and Configurations” on page 28.
You can channelize the Gigabit Ethernet interfaces on PTX10003 routers to create multiple independent
Gigabit Ethernet interfaces and then use breakout cables to connect the channelized ports to other servers,
storage devices, and routers. Here’s the allowable channelization configurations for the optical transceivers
supported by the PTX10003:

PTX10003 Cooling System Description and Airflow
IN THIS SECTION
PTX10003 Fan Modules | 46
PTX10003 Chassis Airflow | 47
Fan Module Status and LED Description | 48
The PTX10003 is cooled front to back with five fan modules (PTX10003-160C) or three fan modules
(PTX10003-80C). Located in the rear of the chassis, the 98.4-W fan modules operate at 164 cubic feet
per minute (CFM) at full speed under zero static pressure. Each fan module is a redundant unit containing
dual counter-rotating fans. The fan modules can be hot-swapped and hot-inserted, meaning that you can
replace a fan module without powering off the router or disrupting the router function.
46
The fan modules pull air through the front panel around the gaps between the optical transceivers. Cooling
for the power supplies is also front to back, utilizing fans inside the power supplies. A separate air plenum
provides air circulation to the power supplies in the entrance at the top of the chassis. There are no air
filters in the PTX10003. Fans are field replaceable but a fan failure must be addressed within one minute
to avoid system shutdown. Access to the fans is from the Field Replaceable Units (FRU) end of the chassis.
Each fan module is composed of two individual fans per tray (10 fans per PTX10003-160C chassis and six
fans per PTX10003-80C chassis). The power requirements of the PTX10003 do not allow for redundant
fan modules.
PTX10003 Fan Modules
The PTX10003 fan modules are hot-removable and hot-insertable FRUs designed for front-to-back airflow.
For the PTX10003-160C, the fan modules are numbered 0 through 4. For the PTX10003-80C, the fan
modules are numbered 1 through 3. Fan modules are installed in fan trays located below the power supplies.
Each fan tray has a fan icon label on the handle.
Figure 13 on page 47 shows a PTX10003 fan module.
Page 46
Figure 13: PTX10003 Fan Module
g100312
Serial number
ID label
You remove and replace a fan module from the FRU end of the chassis. The router continues to operate
for a limited period of time (30 seconds) during the replacement of the fan module without thermal
shutdown.
NOTE: All fan modules must be installed for optimal operation of the router.
47
NOTE: If a fan module fails and the remaining fan modules are unable to keep the PTX10003
within the desired temperature thresholds, chassis alarms are raised and the PTX10003 might shut
down.

Each router has a status LED (labeled ST) for each fan module on the left of the corresponding fan module
slot. The LED indicates the fan module status.

The fan module is operating normally. The system has
verified that the module is engaged, and that the fan is
operating correctly.
An error has been detected in the fan module. Replace
the fan module as soon as possible. Either the fan has
failed or it is seated incorrectly. To maintain proper airflow
through the chassis, leave the fan module installed in the
chassis until you are ready to replace it.
Under normal operating conditions, the fan modules operate at a moderate speed. Temperature sensors
in the chassis monitor the temperature within the chassis.
The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above
the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the
router shuts down automatically.

PTX10003 Power System
IN THIS SECTION
PTX10003 AC/HVDC Power Supply Description | 50
PTX10003 DC Power Supply Description | 59
The PTX10003 is powered by 3000-W redundant AC/HDVC or DC power supplies that are pre-installed
at the factory. The PTX10003-160C is powered by four power supplies for 2+2 redundancy. The
PTX10003-80C is powered by two power supplies for 1 + 1 redundancy. The power supplies are
hot-removable and hot-insertable. If one power supply fails, you can replace it without powering off or
disrupting the routing function. The other power supply balances the electrical load without interruption.
Each power supply has two outputs: 12 V and 12 V standby. Two counter-rotating fans in each power
supply provide front to back cooling. The input voltages are as follows:
50
AC input voltage range: 200—277 V/50—60 Hz
•
DC input voltage range: —40 VDC Min, —72 VDC maximum
•
CAUTION: Do not mix AC/HVDC and DC power supplies in the same chassis.
PTX10003 AC/HVDC Power Supply Description
The input power to the AC/HVDC power supplies can be AC power or HVDC power. The power supplies
automatically detect whether there is AC or HVDC input voltage and manage the power accordingly. AC
power can be 180—305 VAC input voltage and HVDC power can be 190—400 VDC input voltage. Each
3000- W AC/HVDC power supply module has a single AC or HVDC input and provides 12 V power to
the system.
Figure 16 on page 51 shows the location of the AC/HVDC power supplies on the PTX10003-160C FRU
panel, and Figure 17 on page 51 shows the location of the AC/HVDC power supplies on the PTX10003-80C
FRU panel.

PTX10003 DC Input Current Selector (DIP Switch)
The PTX10003 DC power supply can operate with an input current of 80 A or 60 A. You select the input
rating by moving the DC input current selector (DIP switch) to the desired setting. Refer to
Figure 22 on page 61 for the location of the DC input current selector (DIP switch). If you select 60 A, the
power supply limits the output power so that the input current does not exceed 60 A under normal
steady-state operation. If you select 80 A, the power supply limits the output power so that the input
current does not exceed 80 A.
CAUTION: The PTX10003 DC power supply does not support a 60 A power source in
Junos OS Evolved software release 19.1. When installing the PTX10003 DC power supply,
be sure you set the DC input current selector (DIP switch) to 80 A.
Page 62
For example:

Then...If you select...
60 A
80 A
The power supply limits the output power to 2200 W at 40 V input and linearly
increases the output power if the input voltage increases. The power supply provides
3000 W output power for input voltage greater than 55 V assuming 92% efficiency.
CAUTION: The PTX10003 DC power supply does not support a 60 A power source
in Junos OS Evolved software release 19.1. When installing the PTX10003 DC power
supply, be sure you set the DC input current selector (DIP switch) to 80 A.
The power supply provides 3000 W output power throughout the input voltage range
from 40 VDC to 72 VDC.
PTX10003 DC Power Redundancy
To provide power redundancy for the PTX10003, the power supply modules must be connected to an
80 A power source and the input current selector (DIP switch) on the power supply must be set to 80 A.
For the PTX10003-80C, the maximum power budget is 3000 W. For the PTX10003-160C, the maximum
output power budget is 4700 W.
CAUTION:
The PTX10003 DC power supply does not support an 60 A power source in Junos OS Evolved software
release 19.1. When installing the PTX10003 DC power supply, be sure you set the input current selector
to 80 A.
PTX10003 Input DC Voltage Specification
The PTX10003 DC power supply modules operate within the DC input voltage range listed in
Table 20 on page 64.
NOTE: Depending on the available input source, Juniper recommends that the 48-VDC facility DC
source be equipped with a circuit breaker rated at a minimum of 60 A (-48 VDC) or 80 A (-48 VDC),
or as required by local code.

PTX10003 Environmental Requirements and Specifications
The PTX10003 must be installed in a rack. It must be housed in a dry, clean, well-ventilated, and
temperature-controlled environment.
Follow these environmental guidelines:
The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the
•
efficiency of the PTX10003 cooling system.
Maintain ambient airflow for normal PTX10003 operation. If the airflow is blocked or restricted, or if
•
the intake air is too warm, the chassis might overheat, leading to the PTX10003 temperature monitor
shutting down the router to protect the hardware components.
Table 22 on page 73 provides the required environmental conditions for normal PTX10003 operation.

PTX10003 Chassis Grounding Cable and Lug Specifications
For installations that require a separate grounding conductor to the chassis, the PTX10003 must be
adequately grounded before power is connected to ensure proper operation and to meet safety and
electromagnetic interference (EMI) requirements. To ground a PTX10003, connect a grounding cable to
earth ground and then attach it to the chassis grounding point.
WARNING: The device is a pluggable type A equipment installed in a restricted-access
location. It has a separate protective earthing terminal provided on the chassis in addition
to the grounding pin of the power supply cord. This separate protective earthing terminal
must be permanently connected to earth ground for installations that require a separate
grounding conductor to the chassis.
WARNING: To comply with GR-1089 requirements, all intrabuilding copper cabling used
for transceiver ports must be shielded and grounded at both ends.
CAUTION: Before device installation begins, a licensed electrician must attach a cable
lug to the grounding cables that you supply. See “Connecting the PTX10003 to Ground”
on page 110. A cable with an incorrectly attached lug can damage the PTX10003.

PTX10003 Clearance Requirements for Airflow and Hardware Maintenance
When planning the site for a PTX10003 installation, you must allow sufficient clearance around the installed
chassis (see Figure 25 on page 75).
Figure 25: Clearance Requirements for Airflow and Hardware Maintenance for the PTX10003
Follow these guidelines:
For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
•
“PTX10003 Cooling System Description and Airflow” on page 46 for more information about the airflow
through the chassis.
Page 75
If you are mounting a PTX10003 in a rack with other equipment, ensure that the exhaust from other
•
equipment does not blow into the intake vents of the chassis.
You must leave at least 24 in. (61 cm) both in front of and behind the PTX10003 for service personnel
•
to remove and install hardware components.

Rack type: four-post
Mounting bracket
hole spacing
Rack size and
strength
Use a four-post rack that provides bracket holes or hole patterns spaced at 1-U (1.75 in. or
4.45 cm) increments and that meets the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310-D) published by the Electronics Components Industry Association
(http://www.ecianow.org/).
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the
PTX10003 can be mounted in any rack that provides holes spaced at that distance.
Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets,
•
Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the
Electronics Components Industry Association (http://www.ecianow.org/).
Use a 600-mm rack as defined in the four-part Equipment Engineering (EE); European
•
telecommunications standard for equipment practice (document numbers ETS 300 119-1
through 119-4) published by the European Telecommunications Standards Institute
(http://www.etsi.org).
The horizontal spacing between the rails in a rack that complies with this standard is usually
wider than the router’s mounting brackets, which measure 19 in. (48.26 cm) from outer
edge to outer edge. Use approved wing devices to narrow the opening between the rails
as required.
Ensure that the rack rails are spaced widely enough to accommodate the PTX10003 chassis’
•
external dimensions. The outer edges of the front-mounting rails extend the width to 19 in.
(48.26 cm).
Ensure that the front and rear rack rails are spaced between 26 in. (66 cm) and 36 in. (91.4
•
cm) front-to-back.
Ensure that the rack is strong enough to support the weight of the PTX10003.
•
Ensure that the spacing of rails and adjacent racks allows for proper clearance around the
•
PTX10003 and rack.
Rack connection to
building structure
Secure the rack to the building structure.
•
If earthquakes are a possibility in your geographical area, secure the rack to the floor.
•
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

Each of the PTX10003 front panel interfaces support quad small-form factor pluggable (QSFP-DD) optical
transceivers. The interfaces on a PTX10003 can be configured to support 10 Gbps, 40 Gbps, 100 Gbps,
200 Gbps, and 400 Gbps data rates.
You can find information about the optical transceivers supported on your Juniper device by using the
Hardware Compatibility Tool. In addition to transceiver and connection type, the optical and cable
characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool
enables you to search by product, displaying all the transceivers supported on that device, or category, by
interface speed or type. The list of supported transceivers for PTX10003 routers is located at
https://apps.juniper.net/hct/product/#prd=PTX10003.
CAUTION: If you face a problem running a Juniper Networks device that uses a third-party
optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you
diagnose the source of the problem. Your JTAC engineer might recommend that you
check the third-party optic or cable and potentially replace it with an equivalent Juniper
Networks optic or cable that is qualified for the device.

Cable and Connector Specifications for MX and PTX Series Devices
IN THIS SECTION
12-Fiber MPO Connectors | 79
24-Fiber MPO Connectors | 83
LC Duplex Connectors | 84
The transceivers that are supported on MX Series and PTX Series devices use fiber-optic cables and
connectors. The type of connector and the type of fiber depends on the transceiver type.
You can determine the type of cable and connector required for your specific transceiver by using the
Hardware Compatibility Tool.
79
CAUTION: To maintain agency approvals, use only a properly constructed, shielded
cable.
NOTE: The terms multifiber push-on (MPO) and multifiber termination push-on (MTP) describe
the same connector type. The rest of this topic uses MPO to mean MPO or MTP.
12-Fiber MPO Connectors
There are two types of cables used with 12-fiber MPO connectors on Juniper Networks devices—patch
cables with MPO connectors on both ends, and breakout cables with an MPO connector on one end and
four LC duplex connectors on the opposite end. Depending on the application, the cables might use
single-mode fiber (SMF) or multimode fiber (MMF). Juniper Networks sells cables that meet the supported
transceiver requirements, but it is not required to purchase cables from Juniper Networks.
Ensure that you order cables with the correct polarity. Vendors refer to these crossover cables as key up
to key up, latch up to latch up, Type B, or Method B. If you are using patch panels between two transceivers,
ensure that the proper polarity is maintained through the cable plant.
Also, ensure that the fiber end in the connector is finished correctly. Physical contact (PC) refers to fiber
that has been polished flat. Angled physical contact (APC) refers to fiber that has been polished at an angle.
Page 79
Ultra physical contact (UPC) refers to fiber that has been polished flat, to a finer finish. The required fiber
end is listed with the connector type in the Hardware Compatibility Tool.
12-Fiber Ribbon Patch Cables with MPO Connectors
You can use 12-fiber ribbon patch cables with female MPO connectors to connect two transceivers of
the same type—for example, 40GBASE-SR4-to-40GBASESR4 or 100GBASE-SR4-to-100GBASE-SR4. You
can also connect 4x10GBASE-LR or 4x10GBASE-SR transceivers by using patch cables—for example,
4x10GBASE-LR-to-4x10GBASE-LR or 4x10GBASE-SR-to-4x10GBASE-SR—instead of breaking the signal
out into four separate signals.
Table 25 on page 80 describes the signals on each fiber. Table 26 on page 81 shows the pin-to-pin
connections for proper polarity.

12-Fiber Ribbon Breakout Cables with MPO-to-LC Duplex Connectors
You can use 12-ribbon breakout cables with MPO-to-LC duplex connectors to connect a QSFP+ transceiver
to four separate SFP+ transceivers—for example, 4x10GBASE-LR-to-10GBASE-LR or
4x10GBASE-SR-to-10GBASE-SR SFP+ transceivers. The breakout cable is constructed out of a 12-fiber
ribbon fiber-optic cable. The ribbon cable splits from a single cable with a female MPO connector on one
end, into four cable pairs with four LC duplex connectors on the opposite end.
Figure 26 on page 82 shows an example of a typical 12-ribbon breakout cable with MPO-to-LC duplex
connectors (depending on the manufacture, your cable may look different).

You can use patch cables with 24-fiber MPO connectors to connect two supported transceivers of the
same type—for example, 100GBASE-SR10-to-100GBASE-SR10.
Figure 27 on page 84 shows the 24-fiber MPO optical lane assignments.
Page 83
Figure 27: 24-Fiber MPO Optical Lane Assignments
NOTE: Ensure that you order cables with the correct polarity. Vendors refer to these crossover
cables as key up to key up, latch up to latch up, Type B, or Method B. If you are using patch panels
between two transceivers, ensure that the proper polarity is maintained through the cable plant.
The MPO optical connector for the CFP2-100G-SR10-D3 is defined in Section 5.6 of the CFP2 Hardware
Specification and Section 88.10.3 of IEEE STD 802.3-2012. These specifications include the following
requirements:
84
Recommended Option A in IEEE STD 802.3-2012.
•
The transceiver receptacle is male. A patch cable with female connector is required to mate with the
•
module.
Ferrule finish shall be flat polished interface that is compliant with IEC 61754-7.
•
Alignment key is key up.
•
The optical interface must meet the requirement FT-1435-CORE in Generic Requirements for Multi-Fiber
Optical Connectors. The module must pass the wiggle test defined by IEC 62150-3.
LC Duplex Connectors
You can use patch cables with LC duplex connectors to connect two supported transceivers of the same
type—for example, 40GBASE-LR4-to-40GBASE-LR4 or 100GBASE-LR4-to100GBASE-LR4. The patch
cable is one fiber pair with two LC duplex connectors at opposite ends. LC duplex connectors are also
used with 12-fiber ribbon breakout cables, as described in “12-Fiber Ribbon Breakout Cables with
MPO-to-LC Duplex Connectors” on page 81.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion
IN THIS SECTION
85
Signal Loss in Multimode and Single-Mode Fiber-Optic Cable | 85
Attenuation and Dispersion in Fiber-Optic Cable | 86
This topic describes signal loss, attenuation, and dispersion in fiber-optic cable.
Signal Loss in Multimode and Single-Mode Fiber-Optic Cable
Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls
of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not
coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the
light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion.
When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results.
Together these factors limit the transmission distance of multimode fiber compared with single-mode
fiber.
Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only.
Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light,
which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode
fiber has higher bandwidth and can carry signals for longer distances.
Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable
transmission.
Page 85
Attenuation and Dispersion in Fiber-Optic Cable
Correct functioning of an optical data link depends on modulated light reaching the receiver with enough
power to be demodulated correctly. Attenuation is the reduction in power of the light signal as it is
transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and
connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs
in both multimode and single-mode transmission. An efficient optical data link must have enough light
available to overcome attenuation.
Dispersion is the spreading of the signal over time. The following two types of dispersion can affect an
optical data link:
Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.
•
Modal dispersion—Spreading of the signal over time resulting from the different propagation modes in
•
the fiber.
For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually
limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor.
However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion
limits maximum link length.
86
An efficient optical data link must have enough light to exceed the minimum power that the receiver
requires to operate within its specifications. In addition, the total dispersion must be less than the limits
specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and
International Telecommunications Union (ITU) document G.957.
When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in
the power budget. The optical power budget must allow for the sum of component attenuation, power
penalties (including those from dispersion), and a safety margin for unexpected losses.
Calculating Power Budget and Power Margin for Fiber-Optic Cables
Use the information in this topic and the specifications for your optical interface to calculate the power
budget and power margin for fiber-optic cables.
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable
transceivers supported on your Juniper Networks device.
Page 86
To calculate the power budget and power margin, perform the following tasks:
1.
Calculating Power Budget for Fiber-Optic Cable | 87
2.
Calculating Power Margin for Fiber-Optic Cable | 87
Calculating Power Budget for Fiber-Optic Cable
To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate
the link's power budget, which is the maximum amount of power it can transmit. When you calculate the
power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an
actual system do not operate at the worst-case levels. To calculate the worst-case estimate of power
budget (PB), you assume minimum transmitter power (PT) and minimum receiver sensitivity (PR):
87
PB= PT– P
R
The following hypothetical power budget equation uses values measured in decibels (dB) and decibels
referred to one milliwatt (dBm):
PB= PT– P
R
PB= –15 dBm – (–28 dBm)
PB= 13 dB
Calculating Power Margin for Fiber-Optic Cable
After calculating a link's power budget, you can calculate the power margin (PM), which represents the
amount of power available after subtracting attenuation or link loss (LL) from the power budget (PB). A
worst-case estimate of PMassumes maximum LL:
PM= PB– LL
PMgreater than zero indicates that the power budget is sufficient to operate the receiver.
Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion,
connectors, splices, and fiber attenuation. Table 29 on page 87 lists an estimated amount of loss for the
factors used in the following sample calculations. For information about the actual amount of signal loss
caused by equipment and other factors, refer to vendor documentation.
Table 29: Estimated Values for Factors Causing Link Loss

Multimode—None, if product of bandwidth and distance is less than

0.5 dBSplice
Single mode—0.5 dB/km
Multimode—1 dB/km
The following sample calculation for a 2-km-long multimode link with a power budget (PB) of 13 dB uses
the estimated values from Table 29 on page 87 to calculate link loss (LL) as the sum of fiber attenuation
(2 km @ 1 dB/km, or 2 dB) and loss for five connectors (0.5 dB per connector, or 2.5 dB) and two splices
(0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margin (PM) is calculated
as follows:
PM= PB– LL
PM= 13 dB – 2 km (1 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB
PM= 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB
PM= 7 dB
The following sample calculation for an 8-km-long single-mode link with a power budget (PB) of 13 dB
uses the estimated values from Table 29 on page 87 to calculate link loss (LL) as the sum of fiber attenuation
(8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power
margin (PM) is calculated as follows:
PM= PB– LL
PM= 13 dB – 8 km (0.5 dB/km) – 7(0.5 dB)
PM= 13 dB – 4 dB – 3.5 dB
PM= 5.5 dB
In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient
power for transmission and does not exceed the maximum receiver input power.
