Color Optical Light Module
The color light module is a photoelectric converter in an optical multiplexing transmission link, which is also called a WDM wave splitting module.
How the color light module works:
Optical signals with different center wavelengths do not interfere with each other in the same fiber. Therefore, it combines light from different center wavelengths of multiple color optical modules for transmission, which greatly reduces the cost of the link.
Classification of color light modules:
There are two types of color optical modules: CWDM optical module and DWDM optical module. In the same band, there are more types of DWDM optical modules, and the utilization of band resources will be more sufficient.
CWDM optical module VS DWDM optical module:
(1) Classification of CWDM optical modules and DWDM optical modules:
There are two types of CWDM optical modules: CWDM SFP+ optical modules and CWDM SFP optical modules.
There are five types of DWDM optical modules: DWDM XENPAK optical module, DWDM XFP optical module DWDM X2 optical module, DWDM SFP + optical module, and DWDM SFP optical module.
(2) Application of CWDM optical module and DWDM optical module:
CWDM optical modules are widely used in Gigabit Ethernet and point-to-point networks;
DWDM optical modules are mainly used in metropolitan area networks (MANs) and local area networks.
(3) Cost of CWDM optical module and DWDM optical module:
CWDM optical modules cost less than DWDM optical modules, so CWDM optical modules are a good choice for cost-effectiveness.
