The BayStack 450-1GBIC MDA supports the following GBICs:
1000BASE-SX
Uses shortwave 850 nm fiber optic connectors to connect devices over multimode
(550 m or 1,805 ft) fiber optic cable
1000BASE-LX
Uses longwave 1,300 nm fiber optic connectors to connect devices over single mode
(5 km or 3.1 mi) or multimode (550 m or 1,805 ft) fiber optic cable
1000BASE-XD
Uses single mode fiber to connect devices over distances up to 40 km (or 31 mi),
depending on the quality of the cable
1000BASE-ZX
Uses single mode fiber to connect devices over distances up to 70 km (or 43 mi), depending
on the quality of the cable. The ports on this GBIC operate only in full-duplex mode
