摘要： The optical receiver includes: a photoelectric conversion circuit for receiving an optical signal and converting the received optical signal into an electrical signal; a comparator for outputting a first determination signal (S1) when a voltage corresponding to the optical signal does not reach a first threshold value (TH1) and for canceling an output of the S1 when the voltage corresponding to the optical signal exceeds a second threshold value larger than TH1 during the S1 is output; a timing extraction circuit for generating a clock signal based on a frequency and a phase of the electrical signal obtained by the converting and for outputting a second determination signal (S2) when the generated clock signal does not satisfy a predetermined condition; a unit for causing the comparator to output the S1 when the S2 is output; and detects loss of optical signal while one of the S1 and S2 is output.

摘要： Provided are an optical communication module which are capable of reducing a risk that an optical fiber may be detached from the optical fiber support fixture. The optical fiber support fixture includes a cylindrical body portion in which a through hole allowing an optical fiber to pass therethrough is formed. The cylindrical body portion has a circumferential surface portion in which a gap that the optical fiber crosses at a time of allowing the optical fiber to pass through the through hole is formed. The cylindrical body portion has an arbitrary point and another point on a center axis of the cylindrical body portion, the arbitrary point and the another point having different positional correspondence relationships with the gap on planes perpendicular to the center axis passing through the arbitrary point and the another point.
