CWDM technology provides the flexibility to increase capacity
of existing fiber infrastructure by enabling multiple channels
(wavelengths) over the same fiber cabling. Each channel
carries data independently from each other, allowing network
designers to transport different data rates and protocols (T1,T3,
Ethernet, Serial, etc) for different customers or applications.
The wavelengths used with CWDM implementations are
The wavelengths used with CWDM implementations are
defined by the International Telecommunications Union,
reference ITU-T G.694.2, listing eighteen wavelengths from
1270nm to 1610nm with 20nm wavelength spacing.²
ITU-T G.652 single-mode fiber optic cable is not optimized for
ITU-T G.652 single-mode fiber optic cable is not optimized for
CWDM applications due to the high attenuation in the 1360nm
to 1460nm band, centered around 1383nm (the water peak).
The 1390 and 1410 wavelengths are not used on the standard
models of iConverter CWDM/X MUX/DEMUX modules because
of the higher attenuation.
² Note: The ITU standard specifies the exact center wavelength as 1271nm, 1291nm, 1311nm, etc. However, for clarity (and to comply with
general industry conventions) the text in this data sheet refers to these wavelengths as 1270nm, 1290nm, 1310nm, etc.
