Reliability Evaluation of Optical Fiber Protection Channels Based on Practical Coding and Logical Calculation

Abstract:

To solve the reliability assessment challenge of protection channels caused by elements multiplexing. The paper build a weighted-undirected graph of optical fiber protection channels, whose nodes measurement is SDH reliability and reliability of optical fiber as edge weights. Start from the information provided by the actual grid, encode the data according to the most close to the actual data format, developed an algorithm for channels and services reliability assessment based on logical "or" and "exclusive or". The result is verified in a 9-node and 19-channel network in central China Grid, showing that the proposed encoding method and model have good practicability and operability, which can offer grid reference to network optimization, scientific channels arrangement and the maintenance of the protection channels.
