The CWDM MUX&DEMUX ABS module of HYC is a wavelength division multiplexing technology based on TFF (thin film filter), which has a variety of package sizes and wavelength options; It MUX the optical signals of different wavelengths to a single optical fiber for transmission, and the receiving end uses the DEMUX to decompose the signals in the optical fiber into signals of different wavelengths; 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, and is widely used in telecommunications, enterprise network, campus network and other fields.

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

Lower Insertion Loss

Lower insertion loss makes CWDM ABS 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 ABS module, effectively preventing crosstalk between signals and causing distortion of the transmission signal.

Mature Production Technology

The CWDM MUX&DEMUX ABS module of HYC has mature production technology, stable and reliable performance, supports the work in the harsh environment of - 40 ~+85 ℃, and ensures the stable transmission of signals.

Compliance with International Standards

The CWDM MUX&DEMUX ABS module of HYC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.
