Abstract

A system for delivering optical power over an optical conduit includes at least one optical power source delivering optical power to multiple outlet nodes in accordance with a multiple power access methodology.

Claims (25)

1. An optical power transmission system, comprising:

at least one optical power source;

more than one optical power receiver, configured to receive optical power from the optical power source;

an optical conduit coupling the optical power source to the optical power receiver; and

an optical power processing unit, the optical power processing unit controlling output of the optical power source by packeting an optical power signal into optical power packets for use in a multiple power access methodology, wherein the output of the optical power source includes information separate from the optical power packets that is configured to allow an optical powered node to accept or reject the optical power packets, wherein the multiple power access methodology includes a time-based multiple access methodology, and wherein the optical power processing unit is further configured to receive information specifying a power requirement of one or more network nodes downstream of the optical power source, and wherein the optical power packets are based on the information specifying the power requirement of one or more network nodes downstream of the optical power source.

2. The system of claim 1 , wherein the optical conduit includes free-space.

3. The system of claim 1 , wherein the optical conduit includes optical fiber.

4. The system of claim 1 , wherein the optical conduit includes photonic crystal fiber.

5. The system of claim 1 , wherein the optical conduit includes holey fiber.

6. The system of claim 1 , wherein the multiple access methodology includes a frequency-based multiple access methodology.

7. The system of claim 1 , wherein the multiple access methodology includes a spatial division multiple access methodology.

8. The system of claim 1 , wherein the multiple access methodology includes a combination of a frequency-based multiple access and a time-based multiple access.

9. The system of claim 1 , further comprising a first load and a second load, the first load requiring different power characteristics than the second load, wherein the multiple access methodology provides for delivery of power having a first characteristic to the first load and delivery of power having a second characteristic to the second load.

10. A method of transmitting optical power, comprising:

providing optical power from at least one optical power source;

receiving optical power by an optical power receiver from the optical power source via an optical conduit coupling the optical power source to the optical power receiver;

controlling output of the optical power source by packeting an optical power signal into optical power packets for use in a multiple power access methodology, wherein the output of the optical power source includes information separate from the optical power packets that is configured to allow an optical powered node to accept or reject the optical power packets, wherein the multiple power access methodology includes a time-based multiple access methodology; and

a first load and a second load, the first load requiring different power characteristics than the second load, wherein the multiple access methodology provides for delivery of power having a first characteristic to the first load and delivery of power having a second characteristic to the second load.

11. The method of claim 10 , wherein the optical conduit includes free-space.

12. The method of claim 10 , wherein the optical conduit includes photonic crystal fiber.

13. The method of claim 10 , wherein the optical conduit includes holey fiber.

14. The method of claim 10 , wherein the multiple access methodology includes a frequency-based multiple access methodology.

15. The method of claim 10 , wherein the multiple access methodology includes frequency division multiple access (FDMA).

16. The method of claim 10 , wherein the multiple access methodology includes a spatial division multiple access methodology.

17. The method of claim 10 , wherein the multiple access methodology includes any combination of a frequency-based multiple access, a time-based multiple access, and a spatial division multiple access.
