Welcome to the world of cutting-edge optical devices with GEZHI DWDM Red/Blue Filter WDM. Our advanced Red/Blue filter is built on thin-film filter technology and a patented athermal platform, delivering top-notch performance in optical amplification systems and DWDM network applications. With a flat and wide passband, low insertion loss, and high isolation, this device sets new standards for optical efficiency and network optimization.

The GEZHI DWDM Red/Blue Filter WDM is a three-port thin-film filter device. It offers two wavelength "bands" – the Red (λ>1547 nm) and the Blue (λ<1543 nm). These bands are transmitted through the Reflected leg and the Pass leg, respectively. The device is commonly used as a two-way (bidirectional) WDM, where one band is sent to the Common leg, and the other band is delivered from the Common leg. This ingenious design allows for seamless integration of DWDM channels in the Red band and the separation of DWDM channels in the Blue band, streamlining your optical network operations.
