OEM/ODM China Fiber Optic Splice Closure Manufacturers - 4/8 channel CCWDM 4/8-CH Compact CWDM Mux/Demux module Mini CWDM – Qualfiber Detail:

FTTH fiber optical WDM FWDM Module 1310/1490/1550nm FBT splitter 1*2 coupler

Qualfiber’s compact size Coarse Wavelength Division Multiplexers(Mini CWDM, Compact CWDM, CCWDM), are integrated optical modules using DYS’s proprietary optical bench platform which can significantly improve optical performance, while also reduce manufacturing cost. Compare to the common standard CWDM module, Qualfiber’s Mini CWDM takes much smaller package size. Much space can be saved in the application and meanwhile the performance and parameters are also better.All Qualfiber’s CWDM modules are Telcordia qualified.(Meet TELCORDIA GR-1221-CORE) Coarse Wavelength Division Multiplexing (CWDM) is an excellent choice for increasing bandwidth capacity while keeping costs down. The 6com splice/pigtailed ABS module family, based on standard Thin Film Filter (TFF) technology with a proprietary packaging, offers you smallest component dimensions combined with an outstanding performance and reliability.
