Juniper SIB-SFF-PTX-240-S Switch Fabric Module for PTX240

Equipment Overview

The Juniper SIB-SFF-PTX-240-S is a Switch Interface Board (SIB) module designed for the Juniper PTX series of core routers. It delivers high-performance switching for IP/MPLS core and transport networks operating at carrier class. The module is powered by the Juniper Express silicon chipset and runs under Junos OS or Junos Evolved. Its primary role is to enable high-density 100G/400G switching within the PTX chassis. This component is engineered for scalable, resilient backbone deployments.

Main Parameters

• Type: Router module (Switch Interface Board)
• Platform: Juniper PTX series core router chassis
• Chipset: Juniper Express silicon
• Operating System: Junos OS / Junos Evolved
• Switching Capacity: High-density 100G/400G switching
• Routing Support: Segment Routing (SR)
• Form Factor: Hot-swappable (install/replace without service interruption)

Key Advantages

This module is selected for enterprise and operator-grade projects due to its support for high-density 100G/400G switching, which meets the demands of modern IP/MPLS cores. Its compatibility with Segment Routing enables flexible and efficient traffic engineering in large-scale networks. The hot-swappable design ensures minimal operational disruption during maintenance or upgrades. The use of Juniper Express silicon guarantees consistent forwarding performance under heavy load.

Compatibility & Integration

The SIB-SFF-PTX-240-S is compatible with Juniper PTX series chassis that support SIB installation. It requires a corresponding version of Junos OS or Junos Evolved for correct operation. The module integrates into Juniper’s standard core routing architecture, supporting IP/MPLS and Segment Routing deployments.
