Problem statement: Fiber To The Home (FTTH) is optical network that play important role to carry multimedia service to customers. The failure service caused by fiber optic cut or device malfunction always happens and it cannot be avoided. Approach: To solve the failure efficiently and effectively, it is needed a real time monitoring system that can work automatically to detect the failure and perform restoration. Smart wireless system is built to perform this task. It can monitor the optical signal continuously and perform restoration fast. Tapping method is used to take a small part of optical signal that goes to customers. This small amount of optical signal will be processed by converter and microcontroller for monitoring and restoration purpose. Results: Based on our experiment, the best coefficient coupler in this system is 0.1 with the receiver sensitivity 32 dBm. This system also is capable to detect the amplitude of video signal synchronous by real time. Conclusion: The proposed system is the first reported up to this time using RF signal to monitor the optical signal and perform automatic restoration.
