Abstract:
An optical receiving apparatus with frame synchronization technology which makes it easy to activate a frame synchronization established state even if bit errors are produced over a transmission link. The apparatus includes: an optoelectrical converting circuit; a pre-stage synchronizing word detecting circuit; a decoder; a post-stage frame synchronization detecting circuit; and a receiver frame synchronization display output circuit.
