Micro-Optic WDM 3 port C Band Red/Blue filter in DWDM System
3 Port C band Red/Blue Micro-Optics WDM device
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
