The ODN Design for Power Distribution Communication Access Network Based on EPON

To meet the optical distribution network construction requirements of EPON communication system in power distribution communication access network,according to the practical engineering project experiences,an ODN solution is given in the end.In the proposed solution,the optical network is designed by hierarchical,which is composed of two levels,the first aggregation level and the second radial level.The first aggregation level should take consideration that each fiber cable PoP can access to at least two transformer station so that it can get the fiber optics route protection.The second-level radial network can access to the neighboring sites,which can get hand in hand protection.The proposed scheme has advantages of saving cable resources,reducing the difficulty of cable construction and maintaining easily.The actual test results show that the scheme can meet the cable construction and optical power requirements of EPON communication system,which provides strong supports to the construction of optical fiber communication system in power distribution automation.
