The invention provides a test system and method for an optical fiber node. The test system includes: at least one optical fiber link to be tested, wherein each optical fiber link includes nodes located at both ends of the optical fiber link and an optical fiber connecting the two nodes; the interference located at at least one of the nodes A device, configured to apply environmental interference to the optical fiber link to be tested based on the obtained interference parameters; a test device connected to the interference device and each of the nodes, configured to apply environmental interference to the optical fiber link according to a preset environmental interference strategy The interference device sends the interference parameters, and counts the number of data packets sent and received by each node at both ends of the optical fiber link during the operation of the interference device, and based on the ratio of the number of data packets sent and received by each node For the results, each of the nodes is tested. The invention can completely test the network transmission performance of the nodes.
Description
technical field [0001] The invention relates to a test field, in particular to a test system and method for an optical fiber node. Background technique [0002] Optical fiber communication is a communication method in which various electrical signals are transmitted through optical fibers after being modulated by light waves. Optical fiber communication is different from wired communication, which uses metal media to transmit signals, while optical fiber communication uses optical fibers to transmit light waves. The highest frequency used by general communication cables is 9-24 MHz (106 Hz), while the working frequency of optical fibers is between 1014-1015 Hz. Optical Access Network (Optical Access Network) is currently the fastest-growing access network technology, focusing on solving the access problem of narrow-band services such as telephone and the access problem of broadband services such as adjusting data services and multimedia images. [0003] The optical fiber a...
