Abstract
This paper presented a status monitoring system designed to improve fiber-to-the-home (FTTH) engineering work by enabling technicians in central offices to observe, in real time, the usage state of FTTH services for each line in detail when they perform operations such as changing cable routes. This will reduce service interruptions. For FTTH access services, optical network units (ONUs) are installed in customer premises and optical line terminals (OLTs) are installed in the central office. The monitoring system is connected to the fiber section between ONUs and an OLT, and it receives the upstream optical signal from the ONU. This optical signal is converted to 1-bit signal to be processed by computer. Every ONU is equipped with wireless transmitter and PIC microcontroller to send signal to wireless receiver (multipoint to point). The display program is created to monitor the condition of FTTH lines.
