Abstract:
1. A differential code optical transmission and reception device which is applied to an optical communication system to transmit and receive information data by converting it into an optical signal, and which comprises, at a transmission side thereof: a digital signal processing optical transceiver that converts said information data into the optical signal, and transmits it to a communication channel; and which comprises, at a reception side: a reception front end part that receives the optical signal from said communication channel; an O/E conversion part that converts the optical signal received from said communication channel into an electrical signal; a skew correction part that regulates a skew between lanes contained in said electrical signal; a differential decoder that decodes a differential code of the electrical signal which has been skew corrected by said skew correction part; and a lane exchange part that rearranges the electrical signal having passed through said differential decoder into a lane state thereof at the time of transmission in cases where lane exchange has occurred in said communication channel.
