68 GBIC specifications
1000BASE-XD GBIC specifications
The 1000BASE-XD GBIC provides Gigabit Ethernet connectivity using SC
duplex single mode fiber connectors. High-performance optical transceivers
enable Gigabit Ethernet link distances of up to 50 kilometers (km) over
single mode fiber. The GBIC operates in full-duplex mode only. The part
number of this GBIC is AA1419003-E5.
CAUTION
To prevent damage to the optical receiver, ensure that at least 3 dB
of attenuation is present between the transmit and receive ports.
The following table describes standards, connectors, cabling, and distance
for the 1000BASE-XD GBIC.
