CWDM optical module adopts CWDM technology, which can combine optical signals with different wavelengths through an external wavelength division multiplexer. It saves fiber resources by transmitting through one optical fiber. At the same time, the receiving end needs to use the wave-demultiplexer to decompose the complex optical signal. In addition, CWDM optical modules can be plugged into switch or router SFP ports. This article will describe in detail what CWDM optical modules are and what are the differences between CWDM optical modules and other modules.The Main Form Factors and Type of CWDM Optical Modules
There are three types of CWDM optical module form factors: SFP, SFP + and XFP. The transmission distance is generally as follows: 40KM, 80KM, 100KM, and 120KM.
CWDM optical modules can be divided into: CWDM SFP optical module, CWDM GBIC optical module, CWDM SFP + optical module, CWDM XFP optical module, CWDM X2 optical module, CWDMXENPAK optical module and CWDM LX-4 opticalcontinue reading
