LWL Fiber-Optic GBIC Module
The LWL fiber-optic GBIC module, with SC connector color-coded blue, is based on
long wavelength 1300nm lasers supporting 1.0625 Gbps link speeds. This GBIC module
supports 9-micron single-mode fiber. Cables up to 10 kilometers in length with a
maximum of five splices can be used. The GBIC module is shipped with a protective
plug in place and should remain in place if no fiber optic cable is connected to the port.
Figure 1-3 shows a GBIC module.

Passive Copper GBIC Module
The Copper (CU) GBIC module is based on the High-Speed Serial Data Connection
(HSSDC) interface standards. The GBIC provides a female HSSDC connector. Copper
cables up to 13 meters have currently been qualified, thereby supporting ANSI X3.230
FC-PH intra-cabinet requirements. Standard cables with HSSDC-to-DB9 male
connectors are also compatible. Figure 1-4 shows a passive copper GBIC.
