An improved high speed optical receiver provides an output that accurately corresponds to the optical input signal without the distorted signals caused by ac or dc coupled receivers when exposed to signals having varying amplitudes. Delaying and dividing circuits permit the creation of threshold signals which eliminate the drawbacks previously encountered.
