Overview
Hotom compact size Coarse Wavelength Division Multiplexers(Mini CWDM, Compact CWDM, CCWDM), are integrated optical modules using our proprietary optical bench platform which can significantly improve optical performance, while also reduce manufacturing cost. Compare to the common standard CWDM module, Hotcom's compact/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 Hotcom' CWDM modules are Telcordia qualified.(Meet TELCORDIA GR-1221-CORE)
