8CH Mux Demux CWDM Module Fiber Optic Multiplexing 1271nm~1611nm LC/UPC LC/APC

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.

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

- CWDM is ideal for fast and long networks that don’t need more expensive speeds. It’s also ideal for a gradual upgrade of older systems.

- CWDM can be your flexible line that keeps your options open, but you can still utilize other cable designs where the need arises.

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.
