The Gigabit Ethernet Module (GEM), model CSS5-IOM-2GE, contains two
1000-Mbps SFP GBICs; 1000BASE-SX or LX with LC-type connectors, or
1000BASE-T with RJ-45 connectors.
The GEM can use the following GBICs with LC-type connectors:
Long-wavelength SFP GBICs (CSS5-GBIC-LX). The longwave length
•
transceiver (1000BASE-LX) can reach 1,804.4 ft. (550 m) for all multimode
media types. For single-mode fiber, the distance is 16,404 ft. (5,000 m).
Short-wavelength SFP GBICs (CSS5-GBIC-SX). The transceiver distance
•
can reach from 721.8 ft. ( 220 m) to 1,640.4 ft. (500 m), depending on the
quality of the fiber.
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.
