Title:
COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, AND DELAY COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/016056
Kind Code:
A1
Abstract:
A communication apparatus (2) according to the present invention is provided with: a delay measurement unit (43) that, on the basis of a reception time of a delay measurement signal transmitted using a first wavelength from a communication apparatus (1), connected by an optical fiber, and a reception time of a delay measurement signal transmitted from the communication apparatus (1) using a second wavelength different from the first wavelength, calculates the difference between a transfer delay time with respect to the communication apparatus (1) when the first wavelength is used, and a transfer delay time with respect to the communication apparatus (1) when the second wavelength is used; and a delay compensation unit (40) that, on the basis of the difference calculated by the delay measurement unit (43), compensates for a delay time difference that is the difference between a transfer delay time when transmitting a signal to the communication apparatus (1) and a transfer delay time when receiving a signal from the communication apparatus (1).
