Abstract :
Fiber-to-the-home (FTTH) network system is used to transmit video, data and voice signals to users at a high speed level. Therefore, good signals are essential. Thus, to monitor the condition of the signals, a CATV tester device is needed. CATV tester device is designed to measure the CATV signals which are passing through the optical network unit (ONU) at the user´s premises. A single mode optical fiber signal entering the ONU will be obtained by `tapping´ method and the signal then will be fed into the CATV tester unit through optical cable connection. The signals will be converted into audio/video signal and be fed to display panel. This tester will display the received signal on the display panel; if the signal received by the CATV tester device is accompanied by undesired signals and noises, video displayed would degrade; it will then indicate that the main (FTTH trunk line) is probably damaged and needed to be repaired.
