COMMUNICATION SYSTEM PROVIDING OPTICAL/WIRELESS HYBRID COMMUNICATION AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication system which effectively uses advantage of optical fiber communication and advantage of wireless communication.SOLUTION: A communication system 10 includes at least one optical-wireless equipment 12 coupled to a longitudinal side of an optical fiber 11. The optical-wireless equipment 12 has an optical fiber power unit for converting optical power into electrical power, and a wireless communication unit electrically powered by the optical fiber power unit. The optical-wireless equipment 12 has a substrate mounting the optical fiber power unit and the wireless communication unit to the longitudinal side of the optical fiber 11. The wireless communication unit has a radio frequency transmitter, and a signal optical grating coupling the transmitter to the longitudinal side of the optical fiber 11. An antenna is also provided including first and second portions extending in opposite directions along the longitudinal side of the optical fiber 11.
