Cisco Small Form-Factor Pluggable (SFP) Transceiver Modules Maintenance
and Troubleshooting
Document ID: 72370
Introduction
This document provides information about the deployment and troubleshooting of Cisco Small Form-
Factor Pluggable (SFP) Transceiver Modules in Cisco Catalyst Switches. Cisco Transceiver Modules
support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing
platforms. Cisco pluggable transceivers offer a convenient and cost effective solution for the adoption in
data centers, campuses, metropolitan area access and ring networks, and storage area networks.
