Abstract
An optical network remote power supply system is proposed, which is designed for use with an optical network for supplying power to a remote switching unit, and which is characterized by the provision of a light source on the local site which can transmit a light beam via the optical transmission line to the remote site, where the light beam is converted into electricity for storage in an electrical energy storage module, such as a rechargeable battery unit or a capacitor. This feature allows the remote switching unit to be powered by the electricity stored in the electrical energy storage module in the event of a failure to the primary channel when the remote switching unit is responsible for switching to the secondary channel.
Claims13
An optical network remote power supply system for use with an optical network having a local optical data processing unit, a remote optical data processing unit, a local switching unit, a remote switching unit, and an optical transmission line connected between the local optical data processing unit and the remote optical data processing unit and including a primary channel and a secondary channel, the optical network remote power supply system comprising:
- a local power source unit integrated to the local switching unit, the local power supply unit having a light-emitting module for emitting a light beam, and a light-beam multiplexing module coupled to a light output port of the local optical data processing unit for injecting the light beam emitted from the light-emitting module in a multiplexed manner into the optical transmission line and to the remote switching unit;
- and
- a remote power storage unit integrated to the remote switching unit, the remote power storage unit having a light division module for dividing the light beam transmitted from the local power source unit through the optical transmission line, a light-to-electricity transducer module for converting the light beam received by the light division module into electrical energy, and an electrical energy storage module for storing the electrical energy produced by the light-to-electricity transducer module and for driving the remote switching unit with the stored electrical energy.
