Title:
A communication apparatus and a subcarrier frequency control method
Document Type and Number:
Japanese Patent JP6223606
Kind Code:
B2
Abstract:
A communication apparatus including: an optical transmission device including transceivers to transmit and receive optical signals at carrier wave frequencies different from one another; a multiplexing unit to subject the optical signals input from the transceivers to frequency multiplexing; an auxiliary transceiver to perform mixing interference of a frequency multiplexing signal and a local emission light signal having the same frequency setting as a carrier wave frequency used in a control target transceiver, to generate and output a control signal for correcting the carrier wave frequency of the control target transceiver, the auxiliary transceiver being a spare transceiver for the plurality of transceivers; and a control unit to perform control to output, to the control target transceiver, the control signal input from the auxiliary transceiver.
