High Efficiency of PON Network Monitoring and Management

This paper presents a transmission surveillance and protection-based approach for failures/faults over the passive optical network (PON) with an excellent combination of Smart Access Network _ Testing, Analyzing and Database (SANTAD) and Smart Drop Protection Scheme (SDPS). SANTAD is an optical monitoring and management system tool that focused on optical testing and line’s status monitoring in PON with some excellence features added, while SDPS is implemented in the drop region to provide self-protection capabilities against fiber cuts. A tapper circuit is designed to allow the optical time domain reflectometer (OTDR) testing signal to bypass the optical splitter for distant monitoring when emitted in downstream direction. With the assistance of fourth window region at 1,625 nm and de(multiplexing) capabilities of wavelength selective coupler, the status of each fiber link can be displayed onto computer screen. Access Control System (ACS) is function to control the OTDR troubleshooting signals and activate the SDPS restoration scheme according to the type of failure in the drop region of PON. The implementation of the excellent combination in PON shows its contributions on obtains the high accuracy in detecting any occurrence of failures/faults and recovery the failure links within 15 s.
