CWDM TECHNOLOGY
Coarse Wavelength Division Multiplexing (CWDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber. It is reliable and effective solution that can increase the capacity and reach of existing passive optical network. CWDM can be applied in many diverse applications.
It is becoming an important transport architecture due to its main features: lower power dissipation (due to deploying uncooled DFB lasers), smaller size and low cost. CWDM technology involves using a multiplexer to combine wavelengths travelling on different fibers into a single fiber. At the receiver end of the link, a demultiplexer separates the wavelengths and routes them int o different fibers, which all terminate at separate receivers.
As defined in ITU-T G.694.2 and ITU-T G.695, the main characteristic of CWDM transmission is the 20nm spacing between channels, which enables up to 18 channels over the entire transmission band (for example 1271 – 1611nm).
