[0003] Since the optical path design of the ONU device is a single-fiber bidirectional design, the optical signals of different wavelengths are used for transmission and reception (such as the optical signal of 1310nm for transmission and the optical signal of 1490nm for reception), in the same optical fiber, it is impossible to connect the port Perform loopback test, that is, it is impossible to complete the quick test of the transmission and reception performance of the ONU device port at the same time; and the current test of the transmission and reception performance of the ONU device port needs to use an optical oscilloscope and a bit error meter respectively. There are many test equipment and the test topology It is more complicated, and it is not suitable for R&D personnel and test personnel to quickly and conveniently judge the transmission and reception performance of the ONU device port in the actual environment

Description
technical field [0001] The invention relates to the communication field, in particular to an ONU port test circuit, device and system. Background technique [0002] Nowadays, with the rapid development of communication services, the requirements for broadband are constantly increasing. PON (Passive Optical Network) is a light-weight technology in communication networks. Its broadband and high-efficiency access features have become one of the important means for major operators to carry out full-service operations, and have received widespread attention. In the PON network, the performance of transmitting and receiving signals of the ONU equipment port at the client is particularly important. Nowadays, the performance test of the ONU equipment port is mainly divided into the transmission performance test and the reception performance test. When the transmission performance test is performed on the port, It is necessary to connect the attenuator and the oscilloscope, and the ...
