Abstract

The invention provides a method and a system for implementing automatic test of indexes of an optical module. The method comprises the following steps of: according to a predetermined test program, adjusting optical power of a service optical signal output by the optical module to be tested; and monitoring the optical power of the service optical signal received by the optical module to be tested and the corresponding index reference values in real time, and testing the corresponding indexes of the optical module to be tested according to the optical power of the service optical signal received by the optical module to be tested and the corresponding index reference values. Compared with the prior art, the method and the system make automation progress in the index test process of the optical module, save the test time, and improve the index test accuracy of the optical module.

Description

technical field [0001] The invention relates to the technical field of optical modules, and relates to a method and a system for realizing automatic testing of optical module indicators through network element management and amplifying single boards. Background technique [0002] The optical module is an indispensable device in any optical fiber communication system. It belongs to the physical layer device and is the interface between light and electricity. The performance of the optical module determines the optical port index of the optical fiber communication system, which also determines the transmission performance of the optical fiber communication system. The traditional optical module input and output average optical power monitoring and the measurement of the sensitivity and overload point of the optical module are measured by adjusting the adjustable attenuator of the external interface and observing whether there is an alarm on the connected instrument. The disadv...
