What is CWDM?

  • June 13. 2017
According to the global optical market, the CWDM modules are more and more widely used in some network project, so what are CWDM modules? Where is it applied on?...

1. What is CWDM?

CWDM modules is a optical transceiver which combine the CWDM technology ( Coarse Wavelength Division Multiplexer ) and can connect the different wavelength of optical signals via a optical cable, so it can save optical resources.

2. Where is it applied on?

CWDM optical modules are a very economic and efficient network connecting solution.
It is widely used in the Education / Data Center and MAN and FC network field.

3. What are the Advantages of CWDM?

a. Transparent data transmission;
b. Large capacity, make the best of optical large bandwidth resources;
c. Save optical fiber and cost; such as a 80km 8 channels CWDM solution can save: 7 channels * 1200usd/channels = 8400usd;
d. Realizing the long distance transmission;
e. Reducing the power consumption, CWDM is only the 12.5% of the DWDM modules.
