Abstract
The receiver of an optical-fiber transmission system comprises a device for restoring each digital signal comprising a first comparator comparing the level of the electric signal with a first reference level and generating a signal when the level of the electric signal is less than the reference level, a second comparator comparing the level of the electric signal with a second reference level and generating a signal when the level of the electric signal is greater than the reference level, and a summator summing the signals generated by the two comparators.
