Optical fiber line testing system employing test light bypass module for in-service monitoring of ADM ring networks
Yoshitaka Enomoto (NTT Corp.) OFT2009-22
Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a novel optical fiber line testing system operating at 1650 nm using test light bypass modules. We show a new testing configuration for add/drop multiplexer (ADM) ring networks. The test light bypass modules were installed in individual customer buildings so the test light can bypass the ADMs. We evaluated the bit-error performance with a 2.48832 Gbit/s ADM ring network using a prototype test light bypass module. We confirmed that this testing system can monitor the optical fiber cables of an ADM ring network, and that it causes no degradation in transmission quality.
