Product Description of TFF CWDM 3 Ports Device

As a core bare device based on Thin-Film Filter (TFF) technology, this 3-port component enables precise wavelength separation in Coarse Wavelength Division Multiplexing (CWDM) systems. Central wavelength ranging from 1270 to1611nm, it achieves typical 0.3dB insertion loss at Reflection. The device design supports flexible integration into customized optical path configurations, particularly suitable for OEM equipment manufacturers requiring protocol-transparent solutions in metro access networks, PON system, FTTx network and Add/drop channels.
