SFP Transceiver Singlemode or multimode fiber-optic cables attach to switch ports
through SFP transceivers. The fiber-optic transceivers provide duplex
LC® connectors, and can be detached from switch ports (through a
10-pin interface) for easy replacement. The following fiber -optic
transceiver types are available:
•Dual-rate shortwave laser (1.0625 or 2. 1250 Gbps) - Shortwave
laser transceivers (850 nm) provide connectivity:
— At 500 meters (1.0625 Gbps) through 50-micron multimode
fiber-optic cable.
— At 300 meters (2.1250 Gbps) through 50-micron multimode
fiber-optic cable.
— At 300 meters (1.0625 Gbps) through 62.5-micron multimode
fiber-optic cable.
— At 150 meters (2.1250 Gbps) through 62.5-micron multimode
fiber-optic cable.
•Dual-rate longwave laser (1.0625 or 2.1250 Gbps) - Longwave
laser transceivers (1310 nm) provi de co nn ecti vi ty at 1 0 ki l ome ters
through 9-micron singlemode fiber-optic cable.
•Dual-rate extended longwave laser (1.0625 or 2.1250 Gbps) -
Longwave laser transceivers (1310 nm) provide connectivity at 20
or 35 kilometers through 9-micron singlemode fiber-optic cable.
