Optical transceiver, a multiplexing integrated circuit, a demultiplexing integrated circuit, an integral multiplexing/demultiplexing integrated circuit, and method for evaluating and testing the optical transceiver |
摘要 |
An optical transceiver 1 comprises first and second pseudo-random pattern generators 23 and 28 for generating a pseudo-random pattern signal, which are placed in a transmitting side path 6 and in a receiving side path 11 of the optical transceiver 1 , respectively; first and second pseudo-random pattern detectors 21 and 26 for evaluating an inputted pseudo-random pattern signal, which are placed in the transmitting side path 6 and in the receiving side path 11 of the optical transceiver 1 , respectively; a first loopback path 31 that loops back from a multiplexing circuit 3 to a demultiplexing circuit 8 ; and a second loopback path 32 that loops back from a light-electricity converter 7 to an electricity-light converter 4.
