CWDM (Coarse Wavelength Division Multiplexing) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, facilitating multiplication of capacity.
CWDM utilizes laser signals that differ in increments of 20 nm. A total of 18 different channels are available, ranging from 1270 nm to 1610 nm. Since each channel is capable of data rates of 3.125 Gbps, the aggregate ability is 10 Gbps for any CWDM cable. It is ideal for lower cost, lower capacity (sub-10G), and shorter distance applications.
