Abstract |
This paper presents a solution to a technique for automatic protection and restoration switching in conjunction with a capability for intercommunications between customers in a passive optical network. Protection switching against fiber breaks is carried out using an additional device in the immediate split coupled with an ADSL-copper wire from the CO through ACS for control and monitoring purposes. Customer protection device (CPD) comprises of programmable optical switches will be employed at the customer end, just before the ONU to ensure continuous service delivery to customers. The principle mechanism of CPD is based on smart drop protection scheme (SDPS) proposed in earlier paper. Two types of failure conditions in the drop region of tree topology in EPON network are also explained. |
