Gigabit Ethernet Interface
This section describes the Gigabit Ethernet interface:

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:
• GBIC Modules, page 44
• Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card, page 46
• General CWDM GBIC Installation and Usage Guidelines, page 47
• Related CWDM Documentation, page 47
• General Connection Rules for CWDM GBICs, page 47
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.
