DWDM R B filter, Red and Blue band Component



FIBERWDM 1x2 DWDM Red/Blue Band Filter is a passive micro optics component based on environmentally stable thin film filter technology. It is mainly used to separate or combine Red band wavelength signals and Blue band wavelength signals in C Band, in single fiber Bi-directional DWDM systems and high power amplification system. The components are characterized with wide passband, low insertion loss, high return loss, excellent environmental stability and high power handling capability.


FIBERWDM provides customized band filters and connectors to meet special control and applications. The filter units are available with steel tubes, 2-slot 1U rack mounts, Pluggable Module, or ABS boxes.
