Abstract :
In order to work out an exact value of the EPON(Ethernet Passive Optical Network) reliability in the smart distribution grid communication system, this paper proposed a method from both the micro and macro perspectives to calculate the failure rate and the reliability in smart distribution grid. On the micro, the reliability of optical devices in OLT(Optical Line Terminal) and ONU(Optical Network Unit)has been evaluated in different temperature conditions which is based on GR-468-CORE standard. On the macro, the effect of different architectural protections of communication has also been estimated. Trunk and branch protection in the EPON architecture can effectively improve the total reliability of communication.
