FWDM Module, PON CATV 19" Rack Mount

       The FWDM series of products are based on the environment-stable thin-film filter technology and are designed in

accordance with Telcordia standards. Its function is to combine or separate two or several optical signals of different

wavelengths in a wide wavelength range. The products have low insertion loss, Low polarization loss, high isolation

and excellent environmental stability, etc., are ideal devices for EDFA, optical fiber CATV, optical fiber sensing and

other optical fiber communication systems.

      The 3-port filter type wavelength division multiplexer uses excellent film filters to ensure high-quality optical

performance, stability and reliability. The filter type wavelength division multiplexer can realize the multiplexing and

demultiplexing of the optical signals of the two communication windows of 1310nm and 1550nm, which doubles the

transmission capacity of a single fiber, and can also realize fiber bidirectional communication. It is widely used in fiber

upgrades, capacity expansion or introduction of integration New business, such as radio and television,

telecommunications, Internet, etc.
