Abstract

A method of identifying and testing an optical fiber includes emitting light into the optical fiber. The light includes an identification signal and a testing signal. The method also includes reading the identification signal and the testing signal with a single device. The method further includes determining an identity of the optical fiber based on the identification signal with the single device and determining a status of the optical fiber based on the testing signal with the single device.

Claims (25)

1. A method of identifying and testing a plurality of optical fibers, the method comprising:

emitting light into to or more of the plurality of optical fibers, the light comprising identification signals and a common testing signal, wherein the identification signal emitted into each of the two or more optical fibers is unique to each of the two or more optical fibers;

reading the unique identification signal and the common testing signal emitted into at least one of the two or more optical fibers with a single device;

determining an identity of the at least one of the optical fibers based on the unique identification signal emitted into the at least one optical fiber with the single device; and

determining a status of the at least one of the optical fibers based on the common testing signal emitted into the at least one optical fiber with the single device.

2. The method of claim 1 , wherein determining the status of the at least one optical fiber comprises determining a power level of the common testing signal in the at least one optical fiber.

3. The method of claim 1 , wherein the light is emitted into the plurality of optical fibers at an end of each of the optical fibers and read at an intermediate portion of each of the optical fibers.

4. The method of claim 1 , wherein the identification signal comprises a data burst including a start bit and an identification code, and wherein the identification code is unique to each optical fiber of the plurality of optical fibers.

5. The method of claim 1 , wherein the single device is an optical power meter.

6. The method of claim 1 , wherein the single device is a multifiber identifier.

7. The method of claim 1 , wherein the step of emitting comprises emitting the light from a multifiber tracer.

8. The method of claim 1 , wherein emitting the light comprises emitting a repeating pattern of the identification signal and the testing signal.

9. The method of claim 8 , wherein the repeating pattern comprises emitting a plurality of identification signals between each testing signal.

10. The method of claim 1 , wherein the identification signal comprises an eight-bit data pulse.

11. A method of identifying and testing a plurality of optical fibers, the method comprising:

emitting light into each optical fiber of the plurality of optical fibers, the light comprising an identification signal unique to each respective optical fiber of the plurality of optical fibers and a testing signal common to each of the plurality of optical fibers;

reading the identification signal and the testing signal with a single device; and

determining an identity and a status of each optical fiber of the plurality of optical fibers with the single device, wherein the determined identity is based on the unique identification signals emitted into each optical fiber and the determined status is based on the common testing signal.

12. The method of claim 11 , wherein determining the status of each optical fiber of the plurality of optical fibers comprises determining a relative power level of the respective testing signal of each optical fiber of the plurality of optical fibers as compared to a power level of a testing signal of at least one other optical fiber of the plurality of optical fibers.

13. The method of claim 11 , wherein the single device is an optical power meter.

14. The method of claim 11 , wherein the single device is a multifiber identifier.

15. The method of claim 11 , wherein the step of emitting comprises emitting the light from a single multifiber tracer.

16. The method of claim 11 , wherein emitting the light comprises emitting a repeating pattern of each identification signal and each testing signal into each respective optical fiber of the plurality of optical fibers.

17. The method of claim 16 , wherein each repeating pattern comprises emitting a plurality of identification signals between each testing signal of the respective repeating pattern.

18. The method of claim 11 , wherein each identification signal comprises an eight-bit data pulse.
