FWDM can realize the multiplexing and demultiplexing between two communication channel .It can expand the capacity of single fiber to achieve bidirectional communication, which can widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
Filter WDM
The optical filter is an instrument that is used for wavelength selection, which can select required wavelengths from a large number of wavelengths and reject the addition wavelengths. It can used in wavelength selection, the noise filter of the optical amplifier, gain equalization, optical multiplexing /demultiplexing.
Features:
♦ Low insertion loss
♦ Low PDL
♦ High channel isolation
♦ Excellent environmental reliability
Application:
♦ WDM system
♦ CATV
