Abstract

We proposed and developed a fully passive device prototype, named Passive In-line Monitoring (PIM) device, which used to tap out a small ratio of triple-play (data, voice, and video) signals for monitoring purpose without affecting the transmission in tree-structured fiberto-the-home (FTTH) access network. The device will be installed with the main lines in FTTH permanently to allow the field engineers or technicians to simply connect this device to a portable tester unit for transmission surveillance and failure detection. The PIM device is used to sharply determine 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. The entire optical components that had been used in the circuit design including connectors, splices, optical isolators, and optical couplers. The PIM device is able to improve the service reliability and reduce the repairing cost and time.
