50/125 and 62.5/125 micron multimode fiber optic cable (2 km/6562 ft.
maximum distance)
1000BASE-SX (Shortwave Gigabit Fiber) MDA SC connectors for shortwave 850 nm fiber optic connections over multimode
550 m/1805 ft.) fiber optic cable
1000BASE-LX (Longwave Gigabit Fiber) MDA SC connectors for longwave 1300 nm fiber optic connections over single-mode
(3km/9843 ft.) or multimode (550m/1805 ft.) fiber optic cable
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
