Description

【Technical field】 [0001] The invention relates to an output type optical amplifier automatic testing device. 【Background technique】 [0002] With the large-scale popularization of cable television "fiber-to-the-home" network, the demand for multi-output optical amplifiers in the global market is increasing exponentially. It turns out that when each multi-channel output optical amplifier leaves the factory, it is necessary to rely on manual testing of each technical parameter index of each output port to ensure the quality of the factory products. At present, the maximum number of output channels of the multi-channel output optical amplifier has reached 32 channels, and will be expanded to 64 channels in the future; each output signal needs to be tested for C / CTB, C / CSO, MER, BER, the total output optical power and noise figure 6 factory inspection indicators. Using traditional manual testing methods is not only inefficient, but also causes human errors that are difficult t...
