Abstract

This research studies the optical signal level (transmission loss) and video quality of 1550 video signal delivery system in Passive Optical Network (PON)-based intelligent fiber-to-the-home (i-FTTH) for performance monitoring purposes. A simple Optical Power Meter (OPM) loss measurement method is used to fast trace any degradation or failure that occurs in a PON-based i-FTTH network testbed during installation testing and field testing. The link loss for each branch is compared with the reference loss for determining the current condition based on the measurement analysis without using Optical Time Domain Reflectometer (OTDR). The video signals received from customers' locations are observed to verify the current condition of each fiber link. The disrupted signal in failure line is diverted to protection line, but the noise is higher due to extra loss. The level of modulator and gain of Erbium-Doped Fiber Amplifier (EDFA) are adjusted in order to obtain better quality of video signals.
