Active optical cable electrical connector
View Patent ↗An electrical connector that is integrated within an active cable at one end of the active cable, wherein the active cable is configured to communicate over much of its length using one or more optical fibers. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.
1. A connector comprising:
a plurality of electrical traces, including:
two data contacts for communicating a differential data signal to a first electro-optical transducer;
two data contacts for receiving a differential data signal from a first opto-electronic transducer;
a first power contact configured to power circuitry at a first end of an active cable; and
a second power contact configured to power a circuit at a second end of the active cable, wherein the first end of the active optical cable is located across the length of the active cable from the second end, wherein each of the data and power contacts are disposed in a row, one after another;
a serial data contact for communicating serial control data to the active cable; and
a mechanical support for the electrical traces, wherein the electrical traces and mechanical support are structured such that they may connect to an electrical connector of the active cable, the active cable communicating over much of the length of the active cable using optics over at least one optical fiber.
2. A connector in accordance with claim 1 , wherein the connector itself forms a portion of a cable that communicates over much of its length using an electrical conductor.
3. A connector in accordance with claim 2 , wherein the electrical conductor comprises at least one copper wire for communication of data electrically.
4. A connector in accordance with claim 1 , wherein the connector itself forms a portion of an active cable that communicates over much of its length using optics.
5. A connector in accordance with claim 1 , wherein the connector itself forms a portion of a receptacle.
6. A connector in accordance with claim 5 , wherein the receptacle is a portion of a host board.
7. A connector in accordance with claim 1 , wherein the plurality of electrical traces further includes another two data contacts for communicating a second differential data signal to a second electro-optical transducer.
8. A connector in accordance with claim 7 , wherein the plurality of electrical traces further includes another two data contacts for receiving a second differential data signal from a second opto-electronic transducer.
9. A connector in accordance with claim 1 , wherein the serial control data includes a host selected level of equalization.
10. A connector in accordance with claim 1 , wherein the serial control data includes a host selected level of signal pre-emphasis.
11. A connector in accordance with claim 1 , wherein the serial control data includes a loss of signal (LOS) indication.
12. A connector in accordance with claim 1 , wherein the serial control data includes data for control of the first electro-optical transducer.
13. A connector in accordance with claim 12 , wherein the serial control data for control of the first electro-optical transducer is written to nonvolatile memory in the cable.
14. A connector in accordance with claim 1 , wherein the serial control data includes a customer security code.
15. A connector in accordance with claim 1 , wherein the serial control data includes a manufacturer of the active cable authentication code.
