Abstract :
This paper focuses on developing a passive in-line monitoring (PIM) device prototype, which used to tap out a small ratio of triple-play signals for in-service monitoring and failure identifying against fiber fault in fiber-to-the-home (FTTH) access network. This device will be installed with the main lines in FTTH permanently to allow the technicians to simply connect it to a portable tester unit for transmission surveillance and failure detection. The PIM device is used to sharply determine the location of break point before repairing. A passive taper circuit is required to obtain the optical signals to provide a visual way of monitoring the receiving signal performance. This device is potentially to improve the service reliability and reduce the repairing cost and time.
