These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
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.
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;
}
}
}
}
xi
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
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]
xii
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
load complete
For more information about the load command, see CLI Explorer.

System Architecture
The system architecture cleanly separates control operations from packet forwarding operations. This
design eliminates processing and traffic bottlenecks, permitting the QFX10002 to achieve high performance.
Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos
•
operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy,
policing, monitoring, and configuration management. Junos OS is installed on the QFX10002 internal
solid-state drives (SSDs). QFX10002-36Q and QFX10002-72Q have 2 x 32-GB SSD and the
QFX10002-60C has 2 x 64-GB SSDs. The Routing Engine has a 2.5-GHz quad core Intel CPU and has
16 GB of SDRAM on the QFX10002-36Q and QFX10002-72Q. There is 32 GB of SDRAM on the
QX10002-60C.
Forwarding operations are performed by the Packet Forwarding Engines, which include custom ASICs
•
designed by Juniper Networks. The Q5 ASICs enable the QFX10002 to provide up to 2.88 terabits per
second (Tbps) of throughput on the QFX10002-36Q, 5.76 Tbps on the QFX10002-72Q and 12 Tbps
on the QFX10002-60C. The Q5 ASICs are connected to Hybrid Memory Cubes (HMCs). These
high-efficiency memory modules provide packet buffering, virtual output queue (VOQ) memory, and
improved logical system scale.

The cooling system in a QFX10002 consists of three 80-W fan modules that operate at 150 cubic feet
per minute (CFM) at full speed as well as fans housed in the power supplies. Each fan modules has dual
counter-rotating fans. These fan modules can be hot-swapped and hot-inserted, meaning that– you do
not need to power off the switch or disrupt the switching function to replace a module.
in the QFX10002 cooling system, cool air enters through the vents in the port panel and hot air exhausts
through the field-replaceable unit (FRU) panel. This type of airflow is known as airflow out or port-to-FRU

System Software
QFX Series devices use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching,
routing, and security services. Junos OS is installed on a QFX10002 switch’s 25-gigabyte (GB) internal
NAND solid state flash drive. The same Junos OS code base that runs on QFX10002 switches also runs
on all Juniper Networks EX Series switches, and M Series, MX Series, and T Series routers.
For more information about which features are supported on QFX Series devices, see Feature Tracker.
You manage the switch using the Junos OS command-line interface (CLI), which is accessible through the
console and out-of-band management ports on the device.

QFX10002 Component Redundancy
The following hardware components provide redundancy on QFX10002 models:
Power supplies
•
As shown in Table 6 on page 24, the QFX10002-72Q and QFX10002-60C can operate with a single
DC input power supply or a single AC input power supply for 220VAC operation. A minimum of two AC
power supplies are required to operate the QFX10002-72Q and QFX10002-60C at 110VAC. The
QFX1002-36Q can operate with a single DC input power supply or it can operate with a single AC power
supply at 110VAC and 220VAC.
CAUTION: When running the switch in non-redundant mode, install a power supply
cover (QFX10002-PWR-BLNK) in any unused power bays for safety, cooling, and
emissions control.
The recommended configuration is to run the switch with twice as much power as needed, also called
2N, for full power redundancy. To provide additional power for switch redundancy or feed-redundancy,
see Table 6 on page 24.

Cooling system—All models of the QFX10002 have three fan modules. Each fan module is a redundant
•
unit containing two fans. If a fan module fails and is unable to keep the QFX10002 within the desired
temperature thresholds, chassis alarms occur and the QFX10002 device might shut down.
QFX10002 Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The QFX10002 FRUs are
hot-removable and hot-insertable: you can remove and replace them without powering off the switch or
disrupting the switching function.
CAUTION: Replace a failed fan module with a new fan module within one minute of
removal to prevent chassis overheating.
26
Table 7 on page 26 lists the FRUs for the QFX10002-72Q and actions to take before removing them.

The port panel of the QFX10002-36Q consists of 36 quad small-form factor pluggable plus (QSFP+) ports
that support 10-Gbps, 40-Gbps and 100-Gbps port speeds. Of these 36 ports, 12 ports accept QSFP28
transceivers, which are dual speed 40- or 100-Gigabit Ethernet optical transceivers.

Every second and sixth port in a 6XQSFP cage on a QFX10002 supports 100-Gigabit Ethernet using
QSFP28 transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as
40-Gigabit Ethernet, but are recognized as 40-Gigabit Ethernet by default. See Figure 7 on page 30 for a
close up view of a 6XQSFP+ cage. The 100-Gigabit Ethernet are designated by a fine black line underneath
the port. See Figure 8 on page 30. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit
Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. However, when an 100-Gigabit
Ethernet transceiver is inserted into the port, the transceiver is not automatically recognized and is not
seen in the output of the show chassis hardware command. To enable 100-Gigabit Ethernet on the marked
ports, use the set chassis fpc command. For example, to enable port 11 for 100 Gbps speeds:
[edit]
user@switch#
set chassis fpc 0 pic 0 port 11 speed 100g
30
The port then recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet
ports. See Figure 9 on page 31.
Figure 7 on page 30 shows one of the six 6XQSFP+ cages on a QFX10002-36Q.

40-Gbps Channelization
The 40-Gigabit Ethernet ports can operate independently or be bundled with the next two consecutive
ports and channelized into twelve 10-Gigabit Ethernet ports as a port group. Like 100-Gigabit channelization,
only the first and fourth port in each 6XQSFP cage are available to channelize a port group (see
Figure 10 on page 31. The port group must be configured using the set chassis fpc pic port channel-speed
command. For example, to channelize the first switch port, use the set chassis fpc 0 pic 0 port 1
channel-speed 10g command.
31
NOTE: You cannot channelize an individual port. Channelizing configures all three ports in the
port range to four independent 10-Gigabit Ethernet.

Table 9 on page 32 shows the available combinations for the ports. Most 100-Gigabit Ethernet transceiver
ports are used as uplinks. On the QFX10002 device, the ports are enabled by default and the default config
adds the ports to the default VLAN.

Overview
The QFX10002-60C ports support the flexible configuration of 100-Gbps, 40-Gbps, and 10-Gbps. Each
port auto-senses a 100-Gbps QSFP28 or 40-Gbps QSFP transceiver and sets the speed accordingly. Any
of the 60 ports, 0 through 59, can be configured as either uplink or access ports. See Table 10 on page 34.

10-Gigabit Ethernet using DAC breakout cables (DACBO). When configured for channelization, a breakout
•
cable converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports.
35
For a detailed list of supported optical transceivers and electrical cables, see The Hardware Compatibility
Tool.
Channelization
Although he QFX10002-60C autosenses the speed of a transceiver and sets the speed to either 40 Gbps
or 100 Gbps, for channelization you must manually configure the port speed. Any of the 60 physical ports
that are configured for 40 Gbps speeds can be channelized to 4 independent 10-Gigabit Ethernet interfaces
using copper or fiber breakout cables. You can channelize an individual port or a create a port range.
Port behavior is tied to the ASIC associated with the port. You must configure each port individually, in
order to channelize a 40-Gigabit Ethernet port to 4 independent 10-Gigabit Ethernet ports. The first time
a port for an associated ASIC is changed from the default configuration mode (mode D) to the channelization
mode (mode A), the FPC reboots. Subsequent channelization of the ports for that ASIC does not cause
the FPC to reboot. However if one of the channelized ports is changed back to the default, the FPC will
again reboot. See Table 11 on page 36 for the list of available ports and the associated ASIC.
NOTE: Beginning in Junos OS 18.3R1, when the default configuration mode changes to the
channelization mode, only the associated ASIC reboots.
The switch, as a whole, does not have port groups; however, within the ASIC, there are four port groups
shared by the five physical ports. When one of the ports in the port group is channelized, the fifth port is
disabled and cannot be channelized. If ports in all 12 ASICs are channelized, the switch has a maximum of
192 10-Gigabit Ethernet interfaces.
CAUTION: Changing the channelization mode (mode D to mode A or mode A to mode
D) causes the FPC to reboot. Because there can be a slight loss of data while the FPC
reboots, we recommend that you only configure the changes during a maintenance
window.

40-Gbps Channelization
The 40-Gigabit Ethernet ports can operate independently or bundled with the next two consecutive ports
and channelized into twelve 10-Gigabit Ethernet ports as a port group. Like 100-Gigabit channelization,
only the first and fourth port in each 6XQSFP cage are available to channelize a port group (see
Figure 16 on page 40). The port group must be configured using the set chassis fpc pic port channel-speed
command. For example, to channelize the first switch port, use the set chassis fpc 0 pic 0 port 1
channel-speed 10g command.

Table 13 on page 41 shows the available combinations for the ports. Most 100-Gigabit Ethernet transceiver
ports are used as uplinks . On the QFX10002, the ports are enabled by default and the default configuration
adds the ports to the default VLAN.

Each QFX10002 QSFP+ port uses a single bi-colored LED to indicate link status and activity. See
Figure 17 on page 45 for an example of these triangle shaped LEDs.
Figure 17: Port LEDs
The same single bi-colored LED also indicates when the interface is configured and connected using an
optical split cable or a copper DACBO cable to a 10-Gigabit Ethernet port.
45
There are some slight differences in the amber LED behavior depending on the firmware level of the
complex programmable logic device (CPLD) in your switch and the Junos release level running on the
switch. To determine the Junos release level, use the show version command. To determine the CPLD of
your switch, use the show chassis firmware command. For example:

The cooling system in a QFX10002 consists of three 80-W fan modules in a fan tray and two
counter-rotating fans housed in each of the power supplies.
The QFX10002 brings air into the vents in the port panel and exhausts warmed air through the
field-replaceable units (FRU) panel. This type of airflow is known as airflow out or port-to-FRU airflow.
This topic describes:
Fan Modules
The fan modules in a QFX10002 are hot-removable and hot-insertable FRUs designed for port-to-FRU
airflow. The fan modules numbered 0 through 2 are installed in the fan tray located next to the power
supplies. Each fan module slot has a fan icon next to it.
Figure 25 on page 57 shows the 2-U fan module for the QFX10002 models.
Figure 25: Fan Module for the QFX10002
g050375
You remove and replace a fan module from the FRU end of the chassis. The switch 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 switch.

QFX10002 AC Power Supply Description
The AC power supplies in QFX10002 models (see Figure 28 on page 61) are hot-removable, and
hot-insertable field-replaceable units (FRUs) that you can install without powering off the switch or
disrupting the switching function. The QFX10002-36Q switch has two power supplies; the QFX10002-60C
and QFX10002-72Q have four power supplies. All of the power supplies are installed at the factory.
Each of the 1600-W power supplies has a single AC input. A QFX10002 has double the amount of power
supplies needed to power all of the components in the switch, which is known as 2N redundancy. When
the switch has all of the power supplies installed, the switch has full power redundancy. If a power supply
fails or is removed, a second power supply balances the electrical load without interruption. For more on
redundancy configuration options, see “QFX10002 Component Redundancy” on page 23. Each power
supply provides 12-VDC output with a standby voltage of 12 VDC.

The fan in the power supply provides port-to-FRU airflow, which is also known as airflow out (AFO). A
power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

QFX10002 DC Power Supply Description
The DC power supplies in QFX10002 models (see Figure 29 on page 65) are hot-removable and
hot-insertable field-replaceable units (FRUs) that install without powering off the device or disrupting the
switching function. The two 1600-W power supplies in a QFX10002-36Q are installed at the factory and
supply 1200 W of power to the chassis. Likewise, the four 1600-W power supplies in a QFX10002-72Q
switch are installed at the factory and supply 2400 W of power to the chassis.
A QFX10002 has double the amount of power supplies needed to power all of the components in the
switch, which is known as 2N redundancy. When the switch has all of the power supplies installed, the
switch has full power redundancy. If a power supply fails or is removed, a second power supply balances
the electrical load without interruption. For more on redundancy features, see “QFX10002 Component
Redundancy” on page 23. Each power supply provides 12-VDC output with a standby voltage of 12 VDC.

The fan in the power supply provides port-to-FRU airflow, which is also known as airflow out (AFO). A
power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.
Table 24 on page 66 shows the characteristics of the power supply.

(https://www.etsi.org).
The horizontal spacing between the rails in a rack that complies with this standard is usually
wider than the device'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 switch chassis’
•
external dimensions. The outer edges of the front-mounting brackets extend the width to
19 in. (48.26 cm).

Table 33: Cabinet Requirements for the QFX10002
Cabinet size and clearance
GuidelinesCabinet Requirement
The minimum cabinet size for accommodating a QFX10002 is 36 in. (91.4 cm)
deep. Large cabinets improve airflow and reduce the chance of overheating.

Cabinet airflow requirements
When you mount the switch in a cabinet, ensure that ventilation through the
cabinet is sufficient to prevent overheating.
Ensure that the cool air supply you provide through the cabinet adequately
•
dissipates the thermal output of the switch (or switches).
Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet
•
without recirculating into the switch. An open cabinet (without a top or
doors) that employs hot air exhaust extraction from the top allows the best
airflow through the chassis. If the cabinet contains a top or doors,
perforations in these elements assist with removing the hot air exhaust.
Install the switch in the cabinet in a way that maximizes the open space
•
on the FRU side of the chassis. This maximizes the clearance for critical
airflow. The QFX10002 fans exhaust hot air through the fans and power
supplies.
Route and dress all cables to minimize the blockage of airflow to and from
•
the chassis.
Ensure that the spacing of rails and adjacent cabinets allows for the proper
•
clearance around the switch and cabinet.

Before installing the QFX10002, review the following topics to understand the optical and interface
requirements for the system.
Determining Transceiver Support for the QFX10002
The QFX10002 has quad small form-factor pluggable plus (QSFP+) ports for use as uplinks, downlinks, or
as access ports. These 40-Gigabit Ethernet ports support QSFP+ transceivers, QSFP28 transceivers, QSFP+
direct-attach copper (DAC) cables, and DAC breakout cables (DACBO). Each QSFP+ port on either a
QFX10002-72Q or a QFX10002-36Q can be configured to operate as a 10-Gigabit Ethernet interface by
using a breakout cable or as a single 40-Gigabit Ethernet interface.
The QFX10002 also supports using small form-factor pluggable (SFP) and small form-factor pluggable plus
(QSFP+) transceivers to connect the management ports. These transceivers are not supported for use in
the uplinks, downlinks, or access ports.
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 the QFX10002 is located at the Hardware
Compatibility Tool.
84
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 Specifications for QSFP+ and QSFP28 Transceivers
The 40-Gigabit Ethernet QSFP+ and 100-Gigabit Ethernet QSFP28 transceivers that are used in QFX
Series switches use 12-ribbon multimode fiber crossover cables with socket MPO/UPC connectors. The
fiber can be either OM3 or OM4. These cables are not sold by Juniper Networks.
CAUTION: To maintain agency approvals, use only a properly constructed, shielded
cable.
TIP: 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 QSFP+ or QSFP28 transceivers, ensure that the proper polarity is maintained
through the cable plant.
Table 34 on page 85 describes the signals on each fiber. Table 35 on page 86 shows the pin-to-pin
connections for proper polarity.

Understanding QFX Series Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion
IN THIS SECTION
Signal Loss in Multimode and Single-Mode Fiber-Optic Cables | 87
Attenuation and Dispersion in Fiber-Optic Cable | 87
To determine the power budget and power margin needed for fiber-optic connections, you need to
understand how signal loss, attenuation, and dispersion affect transmission. The QFX Series uses various
types of network cables, including multimode and single-mode fiber-optic cables.
Signal Loss in Multimode and Single-Mode Fiber-Optic Cables
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 light sources. They spray varying wavelengths of light into the multimode fiber, which reflect
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 (layers of lower refractive
index material in close contact with a core material of higher refractive index), higher-order mode loss
occurs. Together, these factors reduce the transmission distance of multimode fiber compared to that of
single-mode fiber.
Single-mode fiber is so small in diameter that rays of light 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 to multimode fiber, single-mode fiber
has a higher bandwidth and can carry signals for longer distances. It is consequently more expensive.
87
For information about the maximum transmission distance and supported wavelength range for the types
of single-mode and multimode fiber-optic cables that are connected to the QFX Series, see the Hardware
Compatibility Tool. Exceeding the maximum transmission distances can result in significant signal loss,
which causes unreliable transmission.
Attenuation and Dispersion in Fiber-Optic Cable
An optical data link functions correctly provided that modulated light reaching the receiver has enough
power to be demodulated correctly. Attenuation is the reduction in strength of the light signal during
transmission. Passive media components such as cables, cable splices, and connectors cause attenuation.
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 transmit enough light to
overcome attenuation.
Dispersion is the spreading of the signal over time. The following two types of dispersion can affect signal
transmission through an optical data link:
Chromatic dispersion, which is the spreading of the signal over time caused by the different speeds of
•
light rays.
Modal dispersion, which is the spreading of the signal over time caused by 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 limits the maximum link length.
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 within the limits
specified for the type of link in the 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.
88
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable
transceivers supported on your Juniper Networks device.
To calculate the power budget and power margin, perform the following tasks:
1.
How to Calculate Power Budget for Fiber-Optic Cable | 88
2.
How to Calculate Power Margin for Fiber-Optic Cable | 89
How to Calculate 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):
PB= PT– P
The following hypothetical power budget equation uses values measured in decibels (dB) and decibels
referred to one milliwatt (dBm):
R
PB= PT– P
R
PB= –15 dBm – (–28 dBm)
PB= 13 dB
How to Calculate 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 36 on page 89 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.
89

Multimode—None, if product of bandwidth and distance is less than
500 MHz-km
0.5 dBConnector
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 36 on page 89 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 36 on page 89 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.
