Chapter 5 Ethernet Cards

5.11.3 DWDM and CWDM GBICs

The ONS 15454-supported DWDM GBICs reach up to 100 to 120 km over single-mode fiber and

support 32 different wavelengths in the red and blue bands. Paired with optical amplifiers, such as the

Cisco ONS 15216, the DWDM GBICs allow maximum unregenerated spans of approximately 300 km

(Table 5-23).

CWDM or DWDM GBICs for the G-1K-4 card come in set wavelengths and are not provisionable. The

wavelengths are printed on each GBIC, for example, CWDM-GBIC-1490. The user must insert the

specific GBIC transmitting the wavelength required to match the input of the CWDM/DWDM device for

successful operation (Figure 5-11). Follow your site plan or network diagram for the required

wavelengths.

Figure 5-11 CWDM GBIC with Wavelength Appropriate for Fiber-Connected Device

A G-1K-4 card equipped with CWDM or DWDM GBICs supports the delivery of unprotected Gigabit

Ethernet service over Metro DWDM (Figure 5-12). It can be used in short-haul and long-haul

applications.
