Title:
OPTICAL FIBER POWER SUPPLY SYSTEM AND DATA COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/255636
Kind Code:
A1
Abstract:
Provided are an optical fiber power supply system and a data communication device such that leakage of power supply light can be suppressed even when an optical fiber is damaged. The optical fiber power supply system is for transmitting power supply light and signal light through an optical fiber having a first transmission path made of a core or cladding and a second transmission path made of a cladding and positioned on the outer periphery of the first transmission path. The power supply light is propagated through the first transmission path, and the signal light is propagated through the second transmission path. The data communication device is provided with: a power supply device for outputting the power supply light to the first transmission path; and a transmission unit or reception unit for transmitting or receiving the signal light through the second transmission path. Alternatively, the data communication device is provided with: a power reception device to which the power supply light is input from the first transmission path; and a transmission unit or reception unit for transmitting or receiving the signal light through the second transmission path.
