Product description：
CWDM(Coarse Wavelength Division Multiplexing) Module,As an economical and practical short distance WDM transmission system, the coarse wavelength division multiplexing (CWDM) module is more and more popular in man applications. Because of the advantages of CWDM, such as low cost, low power, small volume, etc., all major operators and system integrators have found a low-cost, high-performance transmission solution.
Purpose: Characteristic:
Multiplexing / demultiplexing All fiber construction
Optical fiber CATV High reliability
Optical fiber testing equipment Excellent optical performance
Single fiber bidirectional transmission
Capacity increase of single fiber system
