Juniper FPC3-PTX-2T-IR Interface Card for PTX5000

Equipment Overview

The Juniper FPC3-PTX-2T-IR is a third-generation interface/line card designed for the PTX5000 core router platform. It is powered by the Juniper Express chipset and operates under Junos OS, delivering 2 Tbps of throughput per card. This module is intended for scaling service provider core networks, enabling high-density 100G aggregation and reliable traffic forwarding in Tier-1/Tier-2 environments. Its primary role is to expand the capacity of existing PTX5000 infrastructures and support IP/MPLS core deployments.

Main Parameters

• Type: Line/interface card for PTX5000 platform
• Throughput: 2 Tbps
• Chipset: Juniper Express
• Operating System: Junos OS
• Generation: 3rd generation (PTX5000 series)
