Abstract

The invention discloses a system and method for measuring the working point of an all-optical PAM regenerator. Firstly, an optical pulse generating unit is used to respectively generate rectangular and trapezoidal periodic test signals, and then sequentially switch to the bypass optical fiber and the all-optical signal to be tested through a 1X2 optical switch. The optical PAM regenerator is connected to the photodetector through the optical multiplexer and the optical attenuator, and the photoelectric conversion output signal is converted by the data acquisition card, and finally the alignment of the output pulse waveform and the input / output power are completed by the offline processing method of the computer. Calculation of transfer function (PTF), determination of working point of all-optical PAM regenerator.

Description

technical field [0001] The invention belongs to the technical field of optical communication information processing, and more specifically relates to a system and method for measuring the working point of an all-optical PAM regenerator. Background technique [0002] The transmission rate and capacity requirements of optical communication continue to increase. In order to obtain higher channel utilization, high-order modulation signals are increasingly used. In long-distance optical fiber communication, optical signals must be processed by functional equipment such as optical switching or optical relay after being transmitted for a certain distance. The current processing process is mainly carried out by "optical-electrical-optical" conversion. With continuous improvement, this processing method gradually becomes a bottleneck. All-optical information processing gets rid of the shackles of electronic bottlenecks, and will become the development trend of optical communication ...
