Research on OBIfree Technology Based on C-DOCSIS+RFoG Network

C-DOCSIS technology is one of the standard techniques to build the NGB network, C-DOCSIS+RFoG architecture is suitable for the network scene of 50 users of one optical node. In order to solve the OBI problem in the C-DOCSIS+RFoG network, together with the optical transmission technology, WDM technology, optical relay scheme, CWDM multi wavelength scheme and DWDM adjustable wavelength scheme are designed. Through comparative analysis and real network verification, it is concluded that the CWDM multi wavelength scheme is a recommended scheme to meet the real network reconstruction.
