5.8.2 GBIC Description
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 a mplifiers, such as the
Cisco ONS 15216, the DWDM GBICs allow maximum unregenerated spans of approximately 300 km
(Table 5 -17).
5.8.2.1.1 Placement of CWDM or DWDM 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 (Figure5-8). Follow your site pl an or network diagram for the required
wavelengths.
Figure5-8 CWDM GBIC with Wavelength Appropriate for Fiber-Connected Device
The Cisco ONS 15454 SDH Procedure Guide contains specific procedures for attaching optical fiber to
GBICs and inserting GBICs into the G-Series card.
