Title:
光受信器
Document Type and Number:
Japanese Patent JP4066588
Kind Code:
B2
Abstract:
Because the phase comparison of the light signal data row and the light clock signal, and the coding of the light signal by the light signal, are simultaneously conducted, the influence of the phase variation in the signal path is not affected in principle, and the optimum phase condition is automatically established/maintained, and thereby, the present invention operates as an all-light type light receiver by which the light data and light clock are reproduced. Further, because the electric signal used herein exists in the range from the DC to the frequency of the difference between the light signal data row and the light clock signal, problems peculiar to the high speed electric signal can be avoided.
