WDM
WDM is referred to as a wavelength division multiplex. Launched by HiOSO, it can be divided into OLT-WDM and ONU-WDM. This communication system can multiplex and demultiplex 1550nm CATV signal and 1310nm/1490nm IP signal so as to be transmitted in one fiber. OLT-WDM is used to multiplex EPON OLT and CATV optical transmitter signals. ONU-WDM is coordinated with OLT-WDM for demultiplexing.
Features of the Wavelength Division Multiplex
1. Low insertion loss
2. Wide wave band
3. Low polarization dependent loss
4. This optical communication equipment adopts FTTX broadband access equipment.
