What is CWDM?

- In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity.

- CWDM full name is Coarse Wavelength Division Multiplexing.

- As the name states, it is a form of multiplexed fiber optics, so CWDM networks can send simultaneous, two-way communication.

- The term “coarse” refers to the wavelength spacing between channels.

- CWDM utilizes laser signals that differ in increments of 20 nm. A total of 18 different channels are available — with a wavelength range from 1610 nm to 1270 nm — and 8 can be utilized in a single system. Since each channel is capable of data rates of 3.125 Gbps, the aggregate ability is 10 Gbps for any CWDM cable.

- Sometimes, it’s easier to understand the value of a piece of technology by comparing it to alternatives.

- In wavelength division multiplexing, DWDM (Dense WDM) is the other popular choice. DWDM has a wavelength spacing of 0.4 nm. That enables a denser packing of signals (hence the name) and can produce much higher data rates — up to 100 Gbps.

- The primary difference between CWDM and DWDM is that chromatic spacing. While DWDM can send and receive more information, the smaller differences reduce the tolerance of the signal and require far more precision in the laser design.

- CWDM is used for lower cost, lower capacity (sub-10G) and shorter distance applications where cost is an important factor.

Descriptions:

- CWDM supports up to 18 wavelength channels transmitted through a fiber at the same time.

- To achieve this, the different wavelengths of each channel are 20nm apart.

- CWDM technology offers a convenient and cost-efficient solution for shorter distances of up to 70 kilometers.

- For distances between 40 and 70 kilometers, CWDM tends to be limited to supporting eight channels.
