Research of Adaptive Control Bi-OADM in Passive Optical Network

Architecture of adaptive control Bi-OADM is presented. Employing alternate-path switching scheme, the bi-directional traffic can be restored promptly under certain direction fiber failure in passive optical network (PON). The results indicate the adaptive control OADM exhibits a low loss (SMSR=15dB). As all the alternate-path switching is performed at optical switches, the administration and management cost can also be easily optimized.
