5.14.3 G1K-4 DWDM and CWDM GBICs
DWDM (15454-GBIC-xx.x, 15454E-GBIC-xx.x) and CWDM (15454-GBIC-xxxx,
15454E-GBIC-xxxx) GBICs operate in an ONS 15454 G-Series card when the card is configured in
Gigabit Ethernet Transponding mode or in Ethernet over SONET mode. DWDM and CWDM GBICs are
both wavelength division multiplexing (WDM) technologies and operate over single-mode fibers with SC
connectors. Cisco CWDM GBIC technology uses a 20 nm wavelength grid and Cisco ONS 15454 DWDM
GBIC technology uses a 1 nm wavelength grid. CTC displays the specific wavelengths of the installed
CWDM or DWDM GBICs. DWDM wavelengths are spaced closer together and require more precise lasers
than CWDM. The DWDM spectrum allows for optical signal amplification. For more information on
G-Series card transponding mode, refer to the Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card
Software Feature and Configuration Guide.
The DWDM and CWDM GBICs receive across the full 1300 nm and 1500 nm bands, which includes all
CWDM, DWDM, LX/LH, ZX wavelengths, but transmit on one specified wavelength. This capability
can be exploited in some of the G-Series transponding modes by receiving wavelengths that do not match
the specific transmission wavelength.
G1K-4 cards with the Common Language Equipment Identification (CLEI) code of WM5IRWPCAA
Note
(manufactured after August 2003) support CWDM and DWDM GBICs. G1K-4 cards manufactured prior
to August 2003 do not support CWDM or DWDM GBICs.
The ONS 15454-supported CWDM GBICs reach up to 100 to 120 km over single-mode fiber and support
eight wavelengths as shown in

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
