A mathematic model was built-up to analyze ODN attenuation event detection in OTDR system of PON
and then combining the mathematic analysis and experimental result
the application value and necessity of wavelength-selective reflector in PON optical link test and diagnosis system were investigated. Based on operators' requirements
several implementations of reflector were proposed and analyzed
and technical requirements for reflector were given. Finally
the international and domestic standardization progress of reflector was introduced.
