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.
