— 1550 nM singlemode (1000BASE-ELX)
* Note: If you use the 1000BASE-SX GBIC with single mode fiber,
you must use mode conditioning patch cords with a
maximum distance of 500m.
■ 8-port, GBIC based module — This module can be configured with
up to 4 GBIC optical modules. It also has two switch ports to the
backplane that provide more than two Gb per second bidirectional
data traffic to the switch. There are four GBICs per port each
capable of one Gb per second. Each GBIC has an oscillated GQ, F-
chip, and packet and lookup memories.
The 8-port GBIC module can support the following GBIC-type
connectors:
— 850 nM multimode (1000BASE-SX)
— 1300 nM singlemode (1000BASE-LX)
— 1550 nM singlemode (1000BASE-ELX)
* Note: If you use the 1000BASE-SX GBIC with single mode
fiber, you must use mode conditioning patch cords
with a maximum distance of 500m.
