Abstract： With the rapid development of communication technology and the increasing number of business types， the emergence of PON technology not only meets the high bandwidth demand for telecommunications services， but also effectively reduces the cost of network construction and operation and maintenance for telecommunications operators. PON technology has become the most commonly used technology for access networks in the actual business process of telecommunications operators. This article studies and analyzes common optical path failures in PON networks， and provides corresponding solutions based on specific situations.

Key words： PON network; optical path failure; test work; optical power
