Abstract

The invention discloses a device for testing the performance of an optical module and aims at providing a convenient and quick test environment. The invention is realized by the following technical scheme: a PC is connected to a server through an RJ45 network cable, is connected to an optical module performance test board through a USB data line, and is connected to an optical power meter throughan RS232 serial line, the optical power meter is connected to an ROSA optical device through an optical fiber splitter, a tested optical module is connected to the test board through a gold finger slot, the average optical power of the TX end of the tested optical module is divided into two by the optical fiber splitter, one path is sent to the ROSA optical device, and the other path is sent to the optical power meter, the PC obtains the average optical power value of the optical module measured by the optical power meter, and then compares the average optical power value with an optical powerthreshold that have been configured by the server, and determines whether the average optical power value of the tested optical module is within a normal range by using the comparison result. An alarm light visually displays various performance test results of the tested optical module.

Description

technical field [0001] The invention relates to an optical module performance testing device mainly used for photoelectric conversion function in the field of optical communication network. Background technique [0002] In the current optical communication network, the optical module is one of the important devices in the optical fiber communication. As one of the important devices, the optical transceiver module (optical module) is widely used in the Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH ), Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI), and Fast Ethernet and Gigabit Ethernet systems. The main function of the optical module in optical fiber communication is photoelectric conversion, which converts the sent electrical signal into an optical signal; through the optical fiber, the optical signal is converted into an electrical signal for transmission. The optical transceiver module is divided into two parts: the tra...
