209418-A

The Model 1000BASE-XD GBIC provides Gigabit Ethernet connectivity using 
SC duplex single-mode fiber connectors. High-performance optical transceivers 
enable Gigabit Ethernet link distances up to 50 kilometers (km) over single-mode 
fiber. The ports operate in full-duplex mode only.

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

1000BASE-XD GBIC.

Note: Nortel Networks recommends that you use an in-line attenuator for 
shorter link distances to avoid overloading the receiver.

Note: The Model 1000BASE-XD GBIC is based on proprietary 
signaling and is compatible with Accelar 1000 Series XD modules.
