Optical receiver and jitter tolerance control method
First Claim
1. An optical receiver, comprising:
- an optical device configured to receive input light and convert the input light to an electric signal;
an equivalent part configured to carry out waveform shaping on the electric signal;
an amplifier configured to amplify the electric signal;
a discrimination part configured to discriminate data of the electric signal;
an input optical power detecting part configured to detect input optical power of the input light; and
a control part configured to make an error rate in the electric signal with respect to the input optical power worse when the input optical power detected by the input optical power detecting part is equal to or less than a value corresponding to minimum receiver sensitivity.

Abstract
An optical receiver includes an optical device that receives input light and converts the input light to an electric signal; an equivalent part that carries out waveform shaping on the electric signal; an amplifier that amplifies the electric signal; a discrimination part that discriminates data of the electric signal; an input optical power detecting part that detects input optical power of the input light; and a control part that makes an error rate in the electric signal with respect to the input optical power worse when the input optical power detected by the input optical power detecting part is equal to or less than a value corresponding to minimum receiver sensitivity.
