Abstract

The invention discloses an EDFA full-automatic test method and system. The system comprises an automatic test device, a test condition template connected with the automatic test device, and a test report; the automatic test device comprises a light path test device and a console server connected with the light path test device; and the light path test device comprises a light source subsystem, a first variable optical attenuator, a first 50/50-spectral-ratio optical coupler, a first 1*3 optical switch, a first optical power meter, a first 1*2 optical switch, a second variable optical attenuator, a second 1*2 optical switch, a second 1*3 optical switch, a second 50/50-spectral-ratio optical coupler, a spectrograph and a second optical power meter. Optical signal adjustment, light path switching, optical power adjustment, data acquisition and analysis judgement processing are automatically realized in a test process; and thus, automatic testing of characteristic performances, such as EDFA gain, noise indexes, EDFA calibration precision, alarm of EDFA products and pump closing, can be realized.

Description

technical field [0001] The present invention relates to an active optical device for amplifying signal light in the field of WDM communication, in particular to a test method and system for an Erbium-doped Optical Fiber Amplifier (EDFA), in particular to a fully automatic EDFA test method and system. Background technique [0002] With the rapid development of information and communication technology, the research and development of optical fiber amplifiers has further expanded the gain bandwidth, pushing the optical fiber communication system to the direction of high speed, large capacity and long distance. Due to the unique performance of optical fiber amplifier, it is widely used in DWDM transmission system, optical fiber CATV and optical fiber access network. [0003] The characteristic characteristics of EDFA include gain (Gain), gain flatness (Gain Flatness), noise figure (NF, Noise Figure), input / output optical power accuracy, alarm function and pump shutdown function...
