WS-U5535-FEFX-SMF

This Cisco network adapter is built for extending network connectivity using fiber optic cables. It allows Supervisor III modules to connect via single-mode fiber, which is common in large campus or enterprise environments where long-distance connections are needed.

Often found in Cisco Catalyst switches, this uplink module is ideal for network administrators looking to maintain stable and fast communication between network segments over greater distances than copper cabling allows. It benefits organizations that require reliable fiber connections to backbone networks or data centers.

Key Features

• Two independent 100BaseFX fiber ports for uplink flexibility
• Compatible with Cisco Supervisor III chassis and modules
• Uses single-mode fiber for extended reach up to several kilometers
• Low latency and high reliability in fiber network environments
• Easy installation within existing Cisco switch infrastructure

This module is widely deployed in enterprise networks where backbone links must run over fiber for distance and interference immunity. It helps maintain consistent network performance and supports the demands of critical business applications.
