5.13 5.13.3 G-1K-4 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 5-27).
CWDM or DWDM GBICs for the G-Series 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 5-13). Follow your site plan or network diagram for the required
wavelengths.
Figure 5-13 CWDM GBIC with Wavelength Appropriate for Fiber-Connected Device
A G-Series card equipped with CWDM or DWDM GBICs supports the delivery of unprotected Gigabit
Ethernet service over Metro DWDM (Figure 5-14). It can be used in short-haul and long-haul
applications.
