CWDM MUX / DEMUX Module High Stability And Reliability For Telecom Networks
FOC COMMUNICATION CO., LTD provides Coarse Wavelength Division Multiplexing (CWDM) modules which are based on thin film filter (TFF) technology. Packaging options include fiber type and integration of taps and detectors for a complete coarse wavelength division multiplexing solution. The products are Telcordia GR-1221-CORE qualified, and RoHS compliant.
It features small size, high reliability, high extensibility, simultaneous transmission of multi-wavelength. CWDM has gained prevalence in multi-wavelength digital transport architectures because it enables the use of very low cost uncooled distributed feedback (DFB) laser transmitters. Moreover, their powering requirements are reduced and reliability is increased.
FOC COMMUNICATION CO., LTD provides whole series of 1xN CWDM products that are tailored for specific applications. All products meet GR-1209-CORE, GR-1221-CORE and ITU-T G.694.2 requirements.
