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
