GBIC Type
Fiber-optic 1000BASE-SX
Fiber-optic 1000BASE-LX/LH
Fiber-optic 1000BASE-ZX
Copper 1000BASE-TX GBIC
Coarse Wave Division Multiplexing (CWDM)
fiber-optic 1000BASE-X GBIC
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z
Note
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.
