Abstract

The invention discloses a system and method for automated testing of a limit optical signal to noise ratio in an optical transport network, and relates to the technical field of communication. The method includes: step S1. an automated platform receives input test parameters, and initializes a system; step S2. a main flow module calls an adjustment module to adjust an attenuation value of a wave channel to be tested, and a critical point of the limit optical signal to noise ratio is obtained; step S3. the main flow module calls a calculation module to calculate an optical signal to noise ratio value at the critical point of the limit optical signal to noise ratio of the wave channel to be tested; step S4. whether a test is completed is judged according to the input test parameters, if the test is completed, step S5 is carried out, and otherwise, step S2 is carried out, and testing of the next wave channel to be tested is continued; and step S5. the main flow module collects data of all wave channels and outputs a test report. The method for automated testing of the limit optical signal to noise ratio in the optical transport network replaces a great deal of repetitive manual testing in a traditional method, improves test efficiency, reduces test cost, and saves a large amount of time and manpower.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a system and method for automatic testing of limit optical signal-to-noise ratio in an optical transmission network. Background technique [0002] The advent of optical communication technology has been developed at a high speed. Since the current network organization is mainly at the electrical layer, and only organizing the network at the electrical layer can no longer meet the rapid growth of social information needs, so optical communication gradually develops from the electrical layer network to the optical layer network, and OTN (Optical Transport Network, Optical Transport Network, transmission network). OTN is a transmission network based on WDM (Wavelength Division Multiplexing, wavelength division multiplexing) and organizes networks at the optical layer, and is a technical requirement for the next-generation backbone transmission network. [0003] In an OTN op...
