Title:
OPTICAL TRANSMISSION SYSTEM AND OPTICAL TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/190636
Kind Code:
A1
Abstract:
An optical transmission system (1) converts a first electrical signal to an optical signal, transmits the converted optical signal, and converts the transmitted optical signal to a second electrical signal. The optical transmission system (1) comprises an electro-optical conversion device (2), an optical transmission path (3), and an opto-electrical conversion device (4). The first electrical signal includes a high frequency communication signal, the frequency being more than 10GHz but not greater than 100GHz. The optical transmission system (1) further comprises an additional signal generation device (6) that generates an additional signal of a low frequency of 1Hz-9MHz. The electro-optical conversion device (2) converts, to an optical signal, the first electrical signal which includes the communication signal and the additional signal generated by the additional signal generation device (6).
