Fiber Fault Localization in FTTH Using Online Monitoring
At present optical fiber cable is used as media to design network and it support high Band width in Gbps speed. Earlier OFC is used to connect the long distance places called OTN (Optical Transport Network) and presently used even in local/access network called OAN (Optical Access Network). Inorder to provides the broadband accessing the PON (Passive Optical Network) used which splits the voice and data at the customer end and this technique has been improved to GPON (Gigabit Passive Optical Network) which provides the higher data rate then the PON . It is also accessible in the Ethernet connectivity called GEPON (Gigabit Ethernet Passive Optical Network). GEPON/GPON/PON terminals used in between the ONT (Optical Network Terminal) and OLT (Optical Line Terminal) terminals.OLT is located at the service providers end and ONT is located at the customer end. Customers are required high QoS and BW and they interested to make SLA (Service Level Agreement) for their service which are expecting from the service providers. The biggest challenge is the maintenance of the network includes localization and identification cable fault in network that ensures maximum QoS.
