E120 and E320 11.1.x Module Guide

This guide provides an overview and description of the line modules (LMs), switch
route processor (SRP) modules, switch fabric modules (SFMs), and input/output
adapters (IOAs) available for the Juniper Networks E120 and E320 Broadband Services
Routers.

NOTE: A release may support multiple versions of a module or IOA. For information,
see Software Compatibility in JUNOSe System Basics Configuration Guide, Chapter 6,
Managing Modules.

Table 1 on page 3 lists the modules and IOAs supported by the router.

This book also contains the following appendixes:

■ IOA Protocol Support on page 53

■ Module and Slot Combinations on page 75

■ Module Name Cross-Reference Information on page 79

■ Product Reclamation and Recycling Program on page 81

For more information about E120 routers, E320 routers, modules, and IOAs, refer
to the following books:

Pairs with IOAs to process data from different types of network connections

■

FFA ASIC

■

Supports a line rate of 128–byte packets on IOAs

■

The 100–Gbps switch fabric allocates 3.4 Gbps of overall bandwidth to each regular

■

line module slot and 10 Gbps of overall bandwidth to each of the turbo slots (slot
2 and slot 4).

The 320–Gbps switch fabric allocates 10 Gbps of overall bandwidth to each line

■

module slot. The line interface on the ES2 4G LM when installed in a 320 Gbps
fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes
in the range 64–1518 bytes or a mixture of packet sizes that represent Internet
mix traffic (IMIX).

IOAs in a slot.

Uses a range of small form-factor pluggable (SFP) transceivers to support different

Uses either optical or copper SFPs.

The optical transceivers are 1000Base-SX, 1000Base-LX, and 1000Base-ZX

The copper transceivers are 1000Base-T compliant.

■

Single-strand SFPs can be used. These SFPs work in pairs and require a matching SFP

■

at the opposite end of the Ethernet connection. For example, an SFP rated at TX 1310,
RX 1550 must be paired with an SFP rated TX 1550, RX 1310 with the same maximum
operating range. See the following corresponding table (Single-strand SFPs Pairing)

■

See “Module and Slot Combinations” on page 75 for more information on combining

■

IOAs in a slot.

Uses a range of small form-factor pluggable (SFP) transceivers to support different

■

modes and cable lengths

Uses either optical or copper SFPs.

■

The optical transceivers are 1000Base-SX, 1000Base-LX, and 1000Base-ZX

■

compliant.

The copper transceivers are 1000Base-T compliant.

■

Single-strand SFPs can be used. These SFPs work in pairs and require a matching SFP

■

at the opposite end of the Ethernet connection. For example, an SFP rated at TX 1310,
RX 1550 must be paired with an SFP rated TX 1550, RX 1310 with the same maximum
operating range. See the following corresponding table (Single-strand SFPs Pairing)
