Micro-Optic WDM 3 port C Band Red/Blue filter in DWDM System
GEZHI 1x2 DWDM Red/Blue Band Filter is a passive micro optics device 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.
In a DWDM module, which uses a Red/Blue filter, a Mux may be combined with a Demux. For example, the Mux combines DWDM channels in the Red band, while the Demux separates DWDM channels in the Blue Band. Using a Red/Blue filter, one can combine the Red Transmit channels and the Blue Receive channels onto a single fiber.
