1. An optical wireless communication system comprising:
a modem for generating output signals for a plurality of optical transceivers in the optical wireless communication system;
the plurality of optical transceivers each comprising an optical emitter and a light sensor for optical communication towards end points, wherein the optical emitter is configured to emit an optical signal based on the output signal of the modem; and
at least one power sourcing equipment capable of powering at least one of the plurality of optical transceivers and the modem wherein the modem comprises:
a power supply unit of the modem configured to supply power to the modem; and
an apparatus for controlling power supply to a modem connected to the plurality of transceivers in the optical wireless communication system, the apparatus being configured to select at least one of the transceivers for reverse power supply to the modem and to establish a power supply connection between the selected transceiver and the power supply unit of the modem.
