Gigabit Ethernet Module Connectors and LEDs

The Gigabit Ethernet Module (GEM), model CSS5-IOM-2GE, contains two

1000-Mbps SFP GBICs with LC-type connectors. The GEM can use either:

•Longwave-length SFP GBICs (CSS5-GBIC-LX). The longwave length transceiver (1000BASE-LX) can reach 550 meters for all multimode media types. For single-mode fiber, the distance is 5,000 meters.

•Shortwave-length SFP GBICs (CSS5-GBIC-SX). The transceiver distance can reach from 220 meters to 500 meters, depending on the quality of the fiber.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.
