Chapter 5 Ethernet Cards
5.14.3 G1K-4 DWDM and CWDM GBICs
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 5-14
). Follow your site plan or network diagram for the required
wavelengths.
Figure 5-14
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 5-15
). It can be used in short-haul and long-haul
applications.
