Abstract

The paper presents a method for the attenuation measurement of the optical path from ONU to OLT in GPON network. Optical power meter is connected to the fiber section via splitter in central office receiving optical signal from all ONU´s. Optical power difference is measured in upstream signal with desired ONU in “on” or “off” state. The difference has a linear relationship with user´s bandwidth. Finally paper describes an experimental setup for confirmation of proposal, the results differ by 2,5% from theoretically calculated. The system will improve the service reliability and reduce the maintenance cost.
