OPTICAL COMMUNICATION DEVICE AND FREQUENCY CONTROL METHOD

Title:

OPTICAL COMMUNICATION DEVICE AND FREQUENCY CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2018/016055

Kind Code:

A1

Abstract:

This optical communication device (103) is for receiving a signal obtained by frequency multiplexing of a plurality of optical signals, each optical signal being composed of a plurality of sub carriers multiplexed, and is provided with: a plurality of transceivers (2-1 to 2-4) each of which performs reception processing of a band in which one optical signal of the plurality of optical signals is included, as the band to be processed, and each of which calculates a frequency offset amount between local light and an optical signal to be received that is the optical signal included in the band to be processed and a carrier wave frequency interval that is a frequency interval between the local light and an optical signal adjacent to the optical signal to be received; and a frequency control unit (6) that calculates an adjustment amount when an optical communication device (101) that is the transmission source of the plurality of optical signals adjusts the frequencies of the plurality of optical signals, on the basis of the frequency offset amounts and the carrier wave frequency intervals calculated by the plurality of transceivers (2-1 to 2-4), and that transmits the calculated adjustment amount to the optical communication device (101) that is the transmission source.
