Abstract
A system and a method for providing electrical power to an optical communication system, in particular a telephone system, between a local or central station and a remote station incorporates a conventional fiber optical cable having an electrical conductor or electrically conductive sheath connected to the local station and the remote station already used for transmitting optical signal. A power source is electrically connected to earth ground and to the electrical conductor or sheath at the local station. A power supply is provided at the remote station and electrically connected to the electrical conductor or sheath and to the earth ground thereat. The power supply receives electrical power from the power source located at the local station via the conductor or sheath and the earth ground, the earth ground serving as a return path. The power supply means can thus provide electrical power to an interface device or any other devices provided in the remote station. The power supply preferably includes a power storage devices such as one or more batteries.
