Distribution drop fiber in-service fault management in enhanced EPON system
AT Liem, IS Hwang, AA Nikoukar… - Optical Switching and …, 2015 - Elsevier
Ethernet passive optical network (EPON) is considered one of the best candidates for next-
generation optical access solutions. Practical and cost-effective survivability and
maintenance mechanisms are therefore becoming the key issues for continued
development of viable EPON solutions. In addition, 80% of faults occur within the first/last
mile. Therefore, in this paper, we propose in-service integrated fault management
mechanisms at the distribution drop fibers (DDFs) in EPON. The proposed mechanisms can …
