Optical module error test device

Abstract

The invention relates to an optical module error testing device and method, comprising two RRU digital intermediate frequency disks, which are respectively marked as RRUA and RRUB, and the digital intermediate frequency disks include a photoelectric conversion module, a CPU module, an FPGA processing module, a Serdes module and a CLOCK module, the CPU module is connected to the FPGA processing module and the upper PC respectively, the FPGA processing module, the Serdes module and the photoelectric conversion module are connected in turn, the CLOCK module is connected to the CPU module, the Serdes module and the FPGA processing module respectively, and the photoelectric conversion module is the one to be tested The optical module of the RRUA and the photoelectric conversion module of the RRUB are connected through optical fibers. Compared with using a bit error tester to test bit errors, the present invention is closer to engineering applications, and the test results are more reliable. It solves the problem that the RRU can perform optical module selection without the cooperation of the BBU. In addition, it has strong versatility. The structure is simple to implement, with few resources and low cost, which is conducive to improving the stability and reliability of the system in practical applications.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a device and method for error testing of an optical module. Background technique [0002] With the development of communication technology and the increasingly fierce market competition, various operators have put forward higher and higher requirements for the performance of equipment. To ensure the stability and reliability of the product function, the bit error rate is an important indicator to measure the quality of the communication system. [0003] In the distributed base station system, the RRU (Remote Radio Unit, remote radio unit) is mainly to complete the modulation from the baseband carrier data to the radio frequency signal, and the demodulation from the radio frequency signal to the baseband carrier data. FORM PLUGGABLE) The optical module realizes the communication with the BBU (Base Band Unit). SFP optical modules can support functions such as ...

Problems solved by technology

[0005] As an optical module manufacturer, the bit error test of the optical module is generally completed by a bit error tester. Since this test is only performed on the SFP optical module in a relatively independent environment, it has not been tested in actual applications, and the optical module The communication rate is gradually increasing, so it is easy to have interface mismatch in actual engineering applications, and problems occur in actual engineering applications, which do not meet the requirements for bit error rate in communication protocols. Therefore, when selecting optical modules, you must Detect the quality of the optical module and test its bit error rate to ensure product stability and reliability
