Abstract:
An optical communication apparatus receives a signal in which optical signals each including multiplexed subcarriers are frequency multiplexed, and includes: transceivers to perform reception process on a processing target band in which any one of the optical signals is included and to calculate a frequency offset amount between local light and a reception target optical signal that is included in the processing target band and calculate a carrier frequency interval between the local light and an optical signal adjacent to the reception target optical signal; and a frequency control unit to calculate an adjustment amount when an optical communication apparatus that is a source of the optical signals adjusts the frequencies of the optical signals based on the frequency offset amount and the carrier frequency interval calculated by the transceivers and to transmit the calculated adjustment amount to the optical communication apparatus that is a source of the optical signals.

Claim (Index 5):
A frequency control method in an optical communication system that comprises a first optical communication apparatus including a plurality of first transceivers capable of transmitting an optical signal in which a plurality of subcarriers are multiplexed and a second optical communication apparatus including a plurality of second transceivers to receive an optical signal transmitted from the first transceivers, the method comprising:\n performing a transmission of generating and transmitting optical signals of different frequencies; performing a first calculation of performing a reception process on a band which is a processing target and in which any one of the optical signals transmitted in the transmission is included, and calculating a frequency offset amount between local light and an optical signal to be received that is an optical signal included in the processing target band and calculating a carrier frequency interval that is a frequency interval between the local light and an optical signal adjacent to the optical signal to be received; performing a second calculation of calculating, on a basis of the frequency offset amount and the carrier frequency interval calculated in the first calculation, a frequency compensation amount for an optical signal transmitted by the first transceivers; and performing an adjustment of adjusting, on a basis of the frequency compensation amount calculated in the second calculation, a frequency of the optical signal transmitted by the first transceivers.
