摘要:
The maintenance of the ODN (optical distribution network) in PONs is discussed. Post-fault maintenance (to detect, locate and restore the faults) and preventive maintenance (to reduce the fault events) are both considered. The use of OTDR based measuring and monitoring systems is examined in detail
