ABSTRACT:
An optical receiver including a demodulator to convert an in-phase signal of a received differential phase modulated optical signal into a first electrical signal, and to convert a quadrature signal of the received differential phase modulated optical signal into a second electrical signal; a decision member deciding logic states of the first and second electrical signals; a logic controller using the decision result of the decision member to control logic states of the first and second electrical signals; and a memory storing information relating to the decision result. The logic controller controls the logic state using the information relating to the decision result stored in the memory.
