Chapter 4 Configuring the Gigabit Ethernet Ports

Installing, Removing, and Maintaining GBICs

Note Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z

1000BASE-LX standard. However, their higher optical quality allows them to

reach 10 kilometers over single-mode fiber (SMF) versus the 5 kilometers

specified in the standard.

Other GBIC media types may be supported as additional technology becomes

available.

Note Because of interoperability issues, Cisco does not support GBICs purchased from

third-party vendors.

Port Cabling Specifications

Table 4-2 provides cabling specifications for the GBICs. The minimum cable

distance for all GBICs listed (MMF [multimode fiber] and SMF) is 6.5 feet (2

meters).
