DWDM OADM Module
The DWDM OADM 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; In the transmission optical path, OADM can upload and download WDM signals without photoelectric conversion, and it is one of the key nodes in WDM optical network. Using OADM can make its network flexible, easy to upgrade and expand its scale, and it is widely used in LAN, MAN, and other fields.

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

WDM-008-CWDM-OADM-Module(en)_03.jpg
Lower Insertion Loss

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