Installing SFP and XFP Transceivers and GBICs

The Model 1000BASE-ZX GBIC provides Gigabit Ethernet connectivity using 
SC duplex single-mode fiber connectors. High-performance optical transceivers 
enable Gigabit Ethernet link distances up to 70 km over single-mode fiber cable. 
The ports operate in full-duplex mode only.

 describes standards, connectors, cabling, and distance for the Model 

1000BASE-ZX GBIC.
