SFP Transceivers (Fiber Optic Connectors)

A single-mode or multimode fiber-optic cable attaches to a port through a small

form plugable (SFP) transceiver. The SFP provides a duplex LC interface, and can

be detached from the switch port for easy replacement. Two fiber-optic

transceiver types are available:

■ Shortwave laser—Shortwave laser SFPs provide short-distance connections

(2 to 500 meters) through 50-micron or 62.5-micron multimode fiber.

■ Longwave laser—Longwave laser SFPs provide long-distance connections

(up to 10 kilometers) through 9-micron single-mode fiber.

■ Extended longwave laser—Extended longwave laser SFPs provide

long-distance connections (up to 35 kilometers) through 9-micron

single-mode fiber.

Cooling Fans

Four fans (each a separate FRU) provide cooling for the switch power supplies

and the control processor (CTP) card, as well as redundancy for continued

operation if a single fan fails.

Each fan FRU can be replaced while the switch is operating.
