Optical power meter based on LAN-WDM wave band

Abstract

The invention discloses an optical power meter based on an LAN-WDM wave band. The optical power meter comprises a photodecomposition multiplexer, a photodiode detecting unit, a micro-control unit, a screen display portion and a power source. According to the photodecomposition multiplexer, a combined wave multi-wave-length optical signal is divided into a plurality of optical signals with different wave lengths; according to the photodiode detecting unit, the optical singles divided by the photodecomposition multiplexer are received through optical fibers and converted into electric signals; according to the micro-control unit, the electric signals output by a photodiode are received and processed; according to the screen display portion, the electric signals processed by the micro-control unit are displayed in a luminous power mode; according to the power source, electricity power is provided for each part. According to the optical power meter based on the LAN-WDM wave band, the luminous power of four waves with different wave lengths of the LAN-WDM wave band can be tested at the same time, reduction of testing procedures and reduction of man-made testing errors are facilitated, and the efficiency for test in batches can be improved.

Description

technical field [0001] The invention relates to a test instrument for an optical transceiver integrated module in optical communication, in particular to a 100G CFP (Centum Form-factor Pluggable, 100Gb / s pluggable optical transceiver) optical module for multi-channel and multiple wavelengths. Optical power meter based on LAN-WDM (Local Area Network-Wavelength Division Multiplexing, LAN-Wavelength Division Multiplexing) band for power testing.

Problems solved by technology

[0003] 100G CFP, as an important photoelectric conversion module on the client side in a 100G system, is in great demand in the entire system. However, the test equipment for 100G CFP optical modules is still relatively scarce, which brings great challenges to the testing of 100G CFP multi-channel and multi-wavelength. question

At present, most module manufacturers test the optical power of 100G CFP optical modules mainly by testing each channel separately, and testing each channel one by one. It is based on the existing single-channel optical power meter. This test The method will increase the error in the process of continuously plugging and unplugging the optical fiber, and the work efficiency is relatively low. Using some single-channel test equipment will make the test steps very complicated, which is not conducive to mass production and testing
