F-tone¡¯s Mini size Coarse Wavelength Division Multiplexers(Mini CWDM, MCWDM), are integrated optical modules using F-tone¡¯s proprietary optical bench platform which can significantly improve optical performance, while also reduce manufacturing costs. Compare to the common standard CWDM module, F-tone's Mini CWDM takes much smaller package size. Much space can be saved in the application and meanwhile the performance and parameters are much better. All F-tone's CWDM modules are Telcordia qualified.(Meet TELCORDIA GR-1221-CORE)
