Description

Overview
The Juniper Networks ERX OC-3 4-Port OC-3 MM Back Card (part number OC3-4MM_I/O) is a high-performance optical interface module designed for the ERX series routers. It provides four independent OC-3 (155.52 Mbps) multimode fiber ports, enabling dense, reliable, and scalable connectivity for carrier and enterprise networks that require synchronous optical networking (SONET) or synchronous digital hierarchy (SDH) transport.

Key Features

Four OC-3 multimode fiber ports on a compact back-plane card
Supports both SONET and SDH framing formats
Hot-swappable design for zero-downtime upgrades
Low power consumption and built-in diagnostics for easy troubleshooting
Compatible with all Juniper ERX routers that accept the OC-3 back card slot

Technical Specifications

Interface type: OC-3 multimode (MM) fiber
Data rate: 155.52 Mbps per port
Connector: LC duplex
Wavelength: 1310 nm
Maximum fiber length: 2 km (OM3) or 550 m (OM1)
Operating temperature: 0 to 40 degrees Celsius
Power supply: 12 V DC, typical draw 3.5 W
Dimensions: 1.75 in (height) x 4.5 in (width) x 0.5 in (depth)

Applications
The ERX OC-3 4-Port MM Back Card is ideal for:

Metro Ethernet aggregation where multiple OC-3 links are required
Carrier backhaul connecting regional hubs to core networks
Enterprise campus networks needing high-availability fiber links
Data center interconnects that rely on SONET/SDH transport for synchronization
Telecom service providers deploying scalable, modular routing solutions

By integrating this module, network operators can expand bandwidth, improve redundancy, and maintain the high reliability standards expected from Juniper Networks equipment.
