Abstract This paper describes an useful scheme of ultra-dense wavelength division multiplexed-passive optical network (UDWDM-PON) meant for the bidirectional transmission of analog video signals to the users in the Optical Network Unit (ONU). Each user has a dedicated wavelength which carries a group of analog video channels. This PON scheme is bidirectional with a long distance of transmission of 100 km typically over a single optical fiber. The video channels designated for a particular user in the ONU can be continuously tuned by a post-detection tunable bandpass filter. Intermodulation distortion (IMD) resulting from a mixing of analog video channels carried by a single wavelength has been calculated for a group of three video channels which lies in the range of –30 dB to –85 dB typically for a set of values of parameters used in practice. This IMD level is fairly acceptable for analog video signal transmission and reception in practice. The novelty of this scheme is that it is long reach.

AbstractFor the effective bearer of P2P-type services, a P2P service bearer reorientation method for passive optical network for long-distance wide access based on P2P protocol message and wire-speed message identification is proposed. However, the reorientation method still has the possibility of relocation failure, so it is modified – that is, an improved P2P service bearer reorientation method based on optical line terminal (OLT) and optical network unit (ONU) cooperation. And the tool NS2 is used for network simulation analysis. Through simulation analysis, it is verified that the modified reorientation method improves the data traffic burden at the core network and at the OLT.
