The invention discloses a device and a method for simultaneous full -duplex data and power transmission over a single optical waveguide. In this device, an optical waveguide connects a base station and a remote station. At the base station a high power laser source emits a first laser beam for carrying power and a base station low power laser source emits a second laser beam for carrying data from the base station to the remote station over the optical waveguide. The optical interface couples the laser beams into the optical waveguide for transmission. The first and second laser beams are received at the corresponding first and second remote station optical receivers. Similarly at the remote station, a third laser beam is emitted by a remote station low power laser source for carrying data from the remote station to the base station and this beam is received at the base station optical receiver. The wavelengths of the first, second and the third laser beams are distinct. |
