CWDM LGX module of FOCC is a wavelength division multiplexing technology based on TFF (thin film filter). It has a variety of package sizes and wavelength options; It multiplexes the optical signals of different wavelengths to a single optical fiber for transmission, and the receiving end uses the demultiplexing to decompose the signals in the optical fiber into signals of different wavelengths, FOCC is equipped with single or double fiber transmission modes; Because of the advantages of CWDM, such as wide band and low requirement for system equipment, it has occupied an important position in the access layer of MAN.

Excellent Performance Parameters (WDM systems with low loss and high isolation)


CWDM MUX and DEMUX LGX module 11



Lower Insertion Loss

Lower insertion loss makes CWDM LGX module
have lower signal attenuation in operation, thus
reducing the power requirement of signal transmitter.



Higher Isolation

The higher isolation value enables sufficient signal isolation
during multi-signal transmission in the CWDM LGX module,
effectively preventing crosstalk between signals and
causing distortion of the transmission signal.
