Abstract
A communication system includes at least one optical-wireless device coupled to a longitudinal side of an optical fiber. The optical-wireless device may include 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 device may include a substrate mounting the optical fiber power unit and the wireless communication unit to the longitudinal side of the optical fiber. The wireless communication unit may include a radio frequency transmitter, and a signal optical grating coupling the transmitter to the longitudinal side of the optical fiber. The radio frequency transmitter in some embodiments may include an ultra-wideband transmitter. A dipole antenna may also be provided including first and second portions extending in opposite directions along the longitudinal side of the optical fiber.
