Abstract

Fiber network security has become a very essential and important topic for optical network. Fault isolation became an important issue in order to provide an efficient fiber network and provide continuous services to the end user without being interrupted by any failure in fiber line. The aim of this study was to develope a video signal detector in order to determine the presence or loss of optical signal in FTTH. Phase detection method is used detect the existence of video signal. This is faster and more accurate than contrast detection. This device can accept an AC-coupled composite (CVBS), luma (Y), or any other video signal with sync and outputs a logic-level signal. The Video Signal Identifier (VSI) output is low when no sync is detected and high impedance when sync is detected. The device operates from a single +3.3V supply and is capable to detect the video signal in less than 2 sec. Hence, it offers a complete solution to detect the presence or loss of video signal with no external components in the FTTH network.
