Description

technical field

[0001] The invention relates to an amplifying device used for reforming and reusing the optical signal during transmission of the optical signal, and belongs to the technical field of optical signal amplifier manufacturing. Background technique

[0002] In an ordinary low-speed electrical communication system, when the electrical pulse signal representing information is transmitted for a certain distance, due to the influence of energy loss, dispersion and noise along the line, its intensity becomes weak, the waveform is distorted, and the signal-to-noise ratio (S / N) decrease and timing jitter and bit error increase, which affects the performance and communication quality of the communication system. Usually, at a certain distance (position) in the system, the method of regenerative relay and forwarding is used to re-amplify the weakened signal, reshape the deformed signal waveform, restore the original standard waveform, and send it after judgment and re-ti...
