Cabling and Specifications

2.dBm = decibels referenced to 1 milliwatt.

3.Dispersion-shifted single-mode fiber-optic cable required for 100-km distance.

4.This distance represents best case conditions, depending on fiber quality, dispersion, and losses due to connectors, nodes, or splices. In the case of the CWDM GBICs, CWDM OADM modules or mux/demux modules are needed for these GBICs to work in any topology other than a point-to-point topology within one building, so the maximum distance is determined by an optical power budget calculation that takes into consideration all sources of loss, including the insertion loss due to the CWDM OADM and mux/demux modules, and might be different from the distance shown in the table. For optical parameter information associated with the CWDM OADM and mux/demux modules, see the “Related CWDM Documentation” section on page 46.

Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card

The 3-Port Gigabit Ethernet line card supports CWDM GBICs. The eight CWDM GBICs available for use with an Ethernet line card are active components that plug into standard GBIC receptacles in the line card. They convert Gigabit Ethernet electrical signals into an optical single-mode fiber (SMF) interface that feeds into a CWDM network through a Cisco optical add/drop multiplexing (OADM) plug-in module or multiplexing/demultiplexing (mux/demux) plug-in module. Figure 34 shows the physical appearance of a CWDM GBIC with one optical port dust plug removed.

The eight CWDM GBICs available for use with a Gigabit Ethernet line card come in eight wavelengths in a range from 1470 nm to 1610 nm. The color dot between the receive and transmit ports and the color band on the label of the Cisco CWDM GBIC identify the wavelength of the GBIC. Table 12 lists the CWDM GBICs and their associated color codes.
