- Abstract
- We propose a method for segment-level fault localization in the optical distribution network (ODN) of 50-gigabit-capable passive optical network systems. The approach utilizes embedded receiver-side functions of optical network units (ONUs) to monitor signal quality metrics such as eye height and APD current. By comparing measurements across multiple ONU receivers under varying ODN loss and reflectance conditions, the faulty segment can be accurately identified. Experimental results confirm that the proposed method enables effective ODN monitoring without additional hardware.
