Overview

The Cisco® 100BASE-X Small Form-Factor Pluggable (SFP) device (Figure 1) is a hot-swappable input/output device that plugs into Fast Ethernet ports, dual-rate Fast/Gigabit Ethernet ports, or Gigabit Ethernet ports of a Cisco switch or router, linking the port with the fiber cabling network.

Main features include the following:

●   Hot-swappable when deployed, the switch or router does not have to reboot

●   Supports the “pay-as-you-populate” model

●   Interchangeable with other 100BASE-X SFPs on the same line card

●   Supports the Cisco quality ID feature that enables the switch or router to identify whether or not the SFP is a Cisco qualified SFP

●   Optically interoperable with respective 100BASE-X Ethernet interfaces on the same link
