GBIC Laser Optical Transceiver Modules

The Gigabit Interface Converters (GBICs) are field-replaceable modules that plug into receptacles on the line card and provide the Gigabit Ethernet optical interface. The GBICs have two optical interfaces—laser transmit (TX) and laser receive (RX)—and an electrical interface (to the line card). All GBIC module types have dual SC connectors. Different GBICs can be ordered for each port on the line card. The 1-Port Gigabit Ethernet and 3-Port Gigabit Ethernet line cards use GBICs to provide the Gigabit Ethernet optical interface.

The following sections provide information on the GBIC and Coarse Wave Division Multiplexing (CWDM) GBIC in Ethernet line cards:

•Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card, page 45

GBIC Modules

Fiber-optic transmission specifications identify two types of fiber: single-mode and multimode. Signals can travel farther through single-mode fiber than through multimode fiber.

The 1-Port Gigabit Ethernet and 3-Port Gigabit Ethernet line cards support multimode fiber through the WS-G5484= GBIC laser optical transceiver module and single-mode fiber through the WS-G5486=, WS-G5487=. The 3-Port Gigabit Ethernet line card also supports CWDM-GBIC-xxxx= GBIC laser optical transceiver modules.

Table 10 describes the operating parameters for available GBIC laser optics.
