Product Detail Information: The Cisco Catalyst WS-G5486 GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet port, linking the port with the fiber-optic network. A gigabit interface converter (GBIC) is a hot-swappable input/output (transceiver) device that plugs into a module's Gigabit Ethernet port, linking the port with the fiber-optic network. The Cisco Catalyst WS-G5486 GBIC with 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX standard. However, the higher optical quality allows it to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard.
