An optical signal waveform recording device comprises an optical receiving module, an optical signal selecting module, an optoelectronic switching module and an optical signal recording module, wherein the optical receiving module, the optical signal selecting module and the optoelectronic switching module are connected in turn through an optical path, and the optoelectronic switching module and the optical signal recording module are connected through a circuit. The optical receiving module is used for receiving the optical signal, including the optical signal to be recorded; the optical signal selecting module is used for selecting the optical signal to be recorded from the received optical signal; the optoelectronic switching module is used for switching the optical signal to be recorded into the optical signal through the optoelectronic switching circuit; the optical signal recording module is used for recording the electrical signal. The inside of the device can be arranged with different optical signal selecting sub-devices, thereby supporting the recording of a plurality of optical signals.

Description

technical field [0001] The invention relates to a DWDM system, in particular to a method and a device for recording an optical signal waveform. Background technique [0002] Dense Wavelength Division Multiplexing (DWDM) is a broadband optical transmission technology that multiplexes multiple optical signals of different wavelengths for transmission, and then demultiplexes the multiple optical signals in the optical fiber after transmission, and sends them to different communication channels. The terminal provides multiple virtual fiber channels on one physical fiber, thus saving a lot of fiber resources. Observing and recording optical signals has become a key and important technology in DWDM technology. [0003] Requirements for optical index testing work: [0004] In the production of WDM product optical circuit boards, multiple optical indicators need to be tested. Different boards have different test environments and methods, and different test environments need to be...
