Patent ID: 8346094

Claim:
A light transmission system comprising: a light transmission module comprising a light transmission path that transmits a data signal as an optical signal, wherein the light transmission module converts the optical signal transmitted through the light transmission path to an electrical signal and outputs the converted optical signal as a binarization signal; an electrical transmission path that outputs a clock signal as a binarization signal; a reception processing unit that performs a reception process on each of the data signal and the clock signal; and a first delay unit that delays a rise start time of the clock signal with respect to a rise start time of the data signal for the binarization signal, wherein a delay amount of the clock signal by the first delay unit is a time less than or equal to a maximum value of a data dependency jitter (DDJ), and wherein when fluctuation in a rise time of the data signal is a sum of a jitter (deterministic jitter) of deterministic component and a jitter (random jitter) of random component: the deterministic jitter is a discrete function distributed according to a peak of a δ function defined for every number of bit continuations N of the data signal; and the delay amount is set between a peak time of a δ function in number of bit continuations 2 and a peak time of a δ function in number of bit continuations N−1.
