Abstract
A signal processing device is connected to an optical transmitter that transmits an Ethernet signal by optical modulation based on a data signal. The signal processing device includes a mapper unit configured to map a plurality of client signals into a frame signal, an encoder configured to encode the frame signal to generate blocks of a number of bits corresponding to the Ethernet signal, and a signal outputter configured to generate the data signal from the blocks and outputs the data signal to the optical transmitter.

A signal processing device connected to an optical transmitter that transmits an Ethernet signal by optical modulation based on a data signal, comprising:
- a mapper unit configured to map a plurality of client signals into a frame signal;
- an encoder configured to encode the frame signal to generate blocks of a number of bits corresponding to the Ethernet signal;
- and
- a signal outputter configured to generate the data signal from the blocks and outputs the data signal to the optical transmitter.
A signal processing device connected to an optical receiver that receives an optically modulated Ethernet signal based on a data signal encoded into blocks of a predetermined number of bits, comprising:
- a decoder configured to decode the data signal output by the optical receiver;
- and
- a demapper configured to demap a plurality of client signals from the frame signal obtained by decoding the data signal.
A signal processing method for a data signal input to an optical transmitter that transmits an Ethernet signal by optical modulation based on the data signal, the method comprising:
- mapping a plurality of client signals into a common frame signal;
- encoding the frame signal to generate blocks of each bit number corresponding to the Ethernet signal;
- and
- generating the data signal from the blocks.
