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;

}

} }

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]

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.

The ACX5000 Universal Metro Routers are Juniper Networks’ top-of-rack router solutions for data centers and campus distribution or aggregation environments. The ACX5000 router portfolio consists of high-performance fixed-configuration routers that add higher port densities, additional scalability, and improved latency to the ACX Series. The ACX5000 routers are available in two models—ACX5048 and ACX5096. See “ACX5000 Router Models” on page 19.

ACX5000 routers offer a compact 1 U model and a 2 U model that provide wire-speed packet performance, very low latency, and a rich set of Layer 2 and Layer 3 features. These routers have a high-throughput Packet Forwarding Engine, and the performance of the control plane running on ACX5000 routers is enhanced by the 1.5 Ghz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The ACX5000 routers include both 10-Gigabit Ethernet and 40-Gigabit Ethernet fixed configurations.

For more information about which features are supported on an ACX5000 routers, see “Protocols and

g000810

Applications Supported by ACX Series Routers” on page 26.

ACX5000 routers use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS is installed on an ACX5000 router’s 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base that runs on an ACX5000 routers also runs on all Juniper Networks QFX and EX Series switches, and J Series, M Series, MX Series, ACX Series and T Series routers.

You manage the router using the Junos OS command-line interface (CLI), accessible through the console and out-of-band management ports on the router.

Benefits of the ACX5048 and ACX5096 Routers

Performance—ACX5000 routers provide wire-speed packet performance, very low latency, and a rich

•

set of Layer 2 and Layer 3 features.

Service virtualization—ACX5000 routers offer service virtualization on a dedicated and customizable

•

KVM-compliant virtual machine that enables you to execute operational scripts and programs for network performance monitoring and analysis.

ACX5048 Router

As shown in Figure 1 on page 18, the ACX5048 is a 10-Gigabit Ethernet enhanced small form-factor pluggable (SFP+) top-of-rack router with 48 SFP+ ports and 6 quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10-Gigabit Ethernet port or as a 1-Gigabit Ethernet port when 1-gigabit optics are inserted. Each QSFP+ port (48 through 53) can operate as a 40-Gigabit Ethernet port or be channelized to operate as four independent 10-Gigabit Ethernet ports (a total of 24 10-Gigabit Ethernet ports). The 6 QSFP+ ports can be used as either access ports or uplink ports. The ACX5048 provides full duplex throughput of 1.44 Tbps. The ACX5048 has a 1 U form factor and is shipped with redundant fans and redundant power supplies. The router can be ordered with front-to-back airflow (air out or AFO) and with AC or DC power supplies.

Figure 1: ACX5048 Port Panel

ACX5048 can be used only as a standalone router.

ACX5096 Router

As shown in Figure 2 on page 19, the ACX5096 is a is a 10-Gigabit Ethernet enhanced small form-factor pluggable (SFP+) top-of-rack router with 96 SFP+ ports and 8 quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10-Gbps port or as a 1-Gbps port. The QSFP+ ports 96 and 100 can operate at native 40 Gbps speed or can be channelized to 4 independent 10 Gbps port speeds. The 8 QSFP+ ports can be used as either access ports or as uplinks. The ACX5096 has a 2 U form factor and is shipped with redundant fans and redundant power supplies.

Field-Replaceable Units in an ACX5000 Router

Field-replaceable units (FRUs) are components that you can replace at your site. The ACX5000 FRUs are hot-insertable and hot-removable: you can remove and replace them without powering off the router or disrupting the routing function.

The following are the ACX5000 FRUs:

Power supplies

•

Fan modules

•

Table 4 on page 21 lists the FRUs for the ACX5000 and actions to take before removing them.

Table 4: FRUs in ACX5000 Routers and Action Required Before Removing Them

Required ActionFRUs

NonePower supplies

NoneFan modules

CAUTION: Replace a failed power supply with a blank panel or new power supply

within one minute of removal to prevent chassis overheating. The router continues to operate with only one power supply running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating. Do not operate the router with missing FRUs for longer than one minute.

NOTE: If you have a Juniper J-Care service contract, register any addition, change, or upgrade

of hardware components at

https://www.juniper.net/customers/csc/management/updateinstallbase.jsp . Failure to do so

can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.

NOTE: Before removing the optical transceivers, we recommend that you disable the interface

using the set interfaces interface-name disable command. See “Disconnecting a Fiber-Optic

Cable from an ACX5000 Router” on page 130.

Understanding Hardware Redundancy of an ACX5000 Router Components and Functionality

The following hardware components provide redundancy on an ACX5000 router:

Power supplies—The ACX5000 router has one or two power supplies. Each power supply provides

•

power to all components in the router. If two power supplies are installed, the two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without interruption.

To provide power redundancy to the system both power supplies must be installed. Connect power source feed A to one power supply and power source feed B to the second power supply.

CAUTION: Do not connect feed A and feed B to the same power supply input

terminal.

Cooling system—The 1 U ACX5048 router has five fan modules; the 2 U ACX5096 router has three fan

•

modules. If a fan module fails and is unable to keep the ACX5000 router within the desired temperature thresholds, chassis alarms occur and the ACX5000 router can shut down.

Protocols and Applications Supported by ACX Series Routers

Table 7 on page 26 contains the first Junos OS Release support for protocols and applications on ACX

Series routers. A dash indicates that the protocol or application is not supported.

NOTE:

The [edit logical-systems logical-system-name] hierarchy level is not supported on ACX Series

•

routers.

The ACX Series routers does not support per-family maximum transmission unit (MTU)

•

configuration. The MTU applied to family inet gets applied to other families as well, even though it can be configured though CLI and visible in show interface extensive output. The only way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet levels, and let it calculate for each family automatically. MTU values are not limited to 1500 but can range between 256 to 9216.

Port Panel of an ACX5048 Router

The port panel of the ACX5048 supports up to a maximum of 72 logical 10 GbE ports when operating as a standalone router. Forty-eight physical ports(0 through 47) support 10 Gbps small form-factor pluggable plus (SFP+) transceivers. These ports can be configured as access ports. All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

The remaining 24 logical ports are available for six 40 GbE ports (48 through 53) that support up to six quad small-form factor pluggable plus (QSFP+) transceivers or QSFP+. Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent 10 Ggps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.

CAUTION: Do not place a copper transceiver in an access port directly above or below

another copper transceiver. Internal damage to the access ports and router can occur. We recommend either using the top port row exclusively, or bottom port row exclusively, for copper transceivers.

The port panel of the ACX5096 router consists of 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) ports. Physical ports(0 through 95) support 10 Gbps SFP+ transceivers and normally are configured as access ports. The eight 40-Gigabit ports (96 through 103) support QSFP+ transceivers and are normally configured as uplinks or Virtual Chassis ports (VCPs). Although the 104 physical ports of the ACX5096 would map to 128 logical ports using channelization, only 104 logical ports are supported.

QSFP+ direct attach copper (DAC) cables

•

QSFP+ to SFP+ direct attach copper break out (DACBO) cables

•

QSFP+ to SFP+ fiber break out cables

•

All 96 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

CAUTION: Do not place a copper transceiver in an access port directly above or below

another copper transceiver. Internal damage to the access ports and router can occur. We recommend either using the top port row exclusively, or bottom port row exclusively, for copper transceivers.

Channelizing Interfaces

The port panel of an ACX5096 supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port restriction, only two of the eight QSFP+ can be channelized. Depending on how you set the system mode for channelization, the behavior of channelization for the QSFP+ changes. The following system modes are available for the ACX5096 router:

Non-oversubscribed

•

All 96 SFP+ ports on the router (PIC 0) are supported. In this mode, the eight QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

Default mode

•

All 96 SFP+ ports on the router (PIC 0) are supported. QSFP+ ports 96 and 100 can be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99, 101, 102, and 103 are disabled.

Chassis Status LEDs on an ACX5000 Router

The ACX5000 routers has four status LEDs on the FRU side of the chassis, next to the management ports (see Figure 11 on page 53).

Fan Module Status | 63

The cooling system in ACX5000 routers consists of fan modules and a single fan in each power supply. The number of fan modules vary depending whether the size of the router is 1 U or 2 U high. All routers can be set up to work in the following airflow direction:

Airflow Out (AFO)—Air comes into the router through the vents in the front panel.

This topic describes:

Fan Modules

The fan modules in ACX5000 routers are hot-insertable and hot-removable field-replaceable units (FRUs). These fan modules are designed for air to enter from the ports to the FRU–Airflow Out. The fan modules are installed in the fan module slots on the management panel of the router next to the power supplies.

Both the 1 U and 2 U versions of ACX5000 fan modules have a similar design with different dimensions. The 1 U ACX5000 routers have 5 fan modules numbered 0 through 4 from left to right, where the 2 U, ACX5096 has 3 fan modules numbered 0 through 2. On all ACX5000 routers, each fan module slot has a fan icon next to it.

Figure 13 on page 61 shows the 1 U fan module and Figure 14 on page 61 shows the 2 U fan module.

Figure 13: 1 U Fan Module Used in ACX5048

Figure 14: 2 U Fan Module Used in ACX5096

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.

The fan module airflow direction (port-to-FRU, AFO) is indicated by either a gold color or the label AIR OUT . Table 13 on page 62 lists the fan module product SKUs and the direction of airflow in them:

Fan Module Status

You can check the status of fan modules through the show system alarms command or by looking at the LEDs next to each fan module.

Each router has a Status LED (labeled ST) for each fan module on the left side of the corresponding fan module slot. It indicates the status of all the fan modules. Table 14 on page 63 describes the Status LED on the fan module in an ACX5000 router.

The individual fan module is present. After the hardware senses the fan module, software ensures the airflow is consistent with the other fan modules and that it is functioning correctly.

Indicates one of the following:

The fan module is not present.

•

The fan module is not functioning normally.

•

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 system shuts down automatically.

AC Power Supply for an ACX5000 Router

The two power supplies in ACX5000 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the router at the factory. You can install replacement power supplies from the management panel without powering off the router or disrupting the router function.

The AC power supply in 1 U ACX5048 is 650 W; the AC power supply in the 2 U ACX5096, is 850 W. Both power supplies look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 16 on page 67).

CAUTION: Do not mix power supplies with different wattage. The system raises an

alarm when a power supply having a different wattage is inserted into the chassis.

See Figure 18 on page 66 for an example of the 1 U design and Figure 19 on page 66 for an example of the 2 U power supply.

To reduce or eliminate RFI from your site wiring, do the following:

Use a twisted-pair cable with a good distribution of grounding conductors.

•

If you must exceed the recommended distances, use a high-quality twisted-pair cable with one

•

ground conductor for each data signal when applicable.

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Some of the problems caused by strong sources of electromagnetic interference (EMI) are:

Destruction of the signal drivers and receivers in the device

•

Electrical hazards as a result of power surges conducted over the lines into the equipment

•

Clearance Requirements for Airflow and Hardware Maintenance for an ACX5000 Router

When planning the site for installing an ACX5000 router, you must allow sufficient clearance around the installed chassis (see Figure 26 on page 81).

Figure 26: Clearance Requirements for Airflow and Hardware Maintenance for an ACX5000 Router

For the cooling system to function properly, the airflow around the chassis must be unrestricted. See

•

“Cooling System and Airflow in an ACX5000 Router” on page 60 for more information about the airflow

through the chassis.

If you are mounting an ACX5000 router in a rack or cabinet with other equipment, ensure that the

•

exhaust from other equipment does not blow into the intake vents of the chassis.

Leave at least 24 in. (61 cm) both in front of and behind the ACX5000 router. For service personnel to

•

remove and install hardware components, you must leave adequate space at the front and back of the router. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

ACX5000 Router Environmental Specifications

The router must be installed in a rack or cabinet. 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 router cooling system.

Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the

•

intake air is too warm, the router might overheat, leading to the router temperature monitor shutting down the device to protect the hardware components.

ACX5000 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the router must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a ACX5000 router, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

WARNING: The router is 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 intra-building copper cabling

used for SFP+ and QSFP+ ports must be shielded and grounded at both ends.

CAUTION: Before router installation begins, a licensed electrician must attach a cable

lug to the grounding cables that you supply. See “Connecting the ACX5000 Router to

Earth Ground” on page 110. A cable with an incorrectly attached lug can damage the

router.

Before connecting the router to earth ground, review the following information:

A protective earthing terminal bracket is provided in the accessory kit for connecting the router to earth

•

ground. This L-shaped bracket attaches to a post on the ACX5000 router left front mounting bracket, providing a protective earthing terminal for the router. The grounding points are studs sized for M4 hex nuts. The grounding points are spaced at 0.625 in. (15.86 mm). M4 hex nuts with integrated washers are provided in the accessory kit.

The grounding lug required is a Panduit LCD10-10A-L or equivalent. This grounding lug is provided in

•

the accessory kit. The grounding lug provided accommodates 14–10 AWG (2–5.3 mm²) stranded wire.

The grounding cable that you provide for a ACX5000 router must be 14 AWG (2 mm²), minimum 60° C

•

wire, or as permitted by the local code.

Cabinet Requirements for an ACX5000 Router

You can mount an ACX5000 router in an enclosure or cabinet that contains a four-post 19-in. open rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Cabinet requirements consist of:

Cabinet size and clearance

•

Cabinet airflow requirements

•

Table 27 on page 85 provides the cabinet requirements and specifications for an ACX5000 router.

Table 27: Cabinet Requirements for an ACX5000 Router

GuidelinesCabinet Requirement

Cabinet size and clearance

Cabinet airflow requirements

The minimum cabinet size for accommodating a ACX5000 router is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.

When you mount the router 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 router (or routers).

Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet

•

without recirculating into the router. 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.

The ACX5000 router fans exhaust hot air either through the vents on the

•

port panel or through the fans and power supplies. Install the router 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.

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 router and cabinet.

Determining Transceiver Support for the ACX5000

All the router models of the ACX5000 router supply quad small form-factor pluggable plus (QSFP+) ports for use as uplinks or as access ports. These 40 GbE ports support QSFP+ transceivers, QSFP+ direct-attach copper (DAC) cables, and DAC breakout cables (DACBO). The ACX5048 has 6 QSFP+ ports; the ACX5096 has 8 QSFP+ ports that can all be used as uplinks.

On all ACX5000 routers, the ports are enabled by default.

Downlink ports are product SKU-specific:

ACX5096—has 96 SFP+ ports that support SFP and SFP+ transceivers, as well as DAC cables.

•

ACX5048—has 48 SFP+ ports that support SFP and SFP+ transceivers, as well as DAC cables.

•

You can find information about the pluggable transceivers supported on your Juniper Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector 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 ACX5000 is located at

https://pathfinder.juniper.net/hct/product/#prd=ACX5000.

CAUTION: If you face a problem running a Juniper Networks device that uses a

Cable Specifications for QSFP+ and QSFP28 Transceivers

The 40GbE quad small form-factor pluggable plus (QSFP+) and 100GbE quad small form-factor pluggable 28 (QSFP28) transceivers that are used in ACX Series routers use 12-ribbon multimode fiber crossover cables with MPO socket connectors (SR4 optics only). The fiber can be either OM3 or OM4. Juniper Networks does not sell these cables.

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+ transceivers or two QSFP28 transceivers, ensure that the proper polarity is maintained through the cable plant.

Table 29 on page 90 describes the signals on each fiber. Table 30 on page 91 shows the pin-to-pin

connections for proper polarity.

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.

To calculate the power budget and power margin, perform the following tasks:

How to Calculate Power Budget for Fiber-Optic Cable | 92

How to Calculate Power Margin for Fiber-Optic Cable | 92

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):

PB= PT– P

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 31 on page 92 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.

Estimated Link-Loss ValueLink-Loss Factor

0.5 dBConnector

0.5 dBSplice

Fiber attenuation

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 31 on page 92 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 31 on page 92 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.

IN THIS SECTION

Attenuation and Dispersion in Fiber-Optic Cable | 94

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.

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.

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.
