Abstract

Embodiments include methods, apparatus, and systems for cable monitoring. One embodiment includes a method that receives data from an optical transceiver coupled to a cable and a RFID (radio frequency identification) device mounted to the cable. The data from the optical transceiver and RFID device is used to determine an operational status of the cable.

Claims

1. A method, comprising:

collecting, from an optical transceiver coupled to a cable, data that includes one of laser information and optical power information;

receiving the data from the optical transceiver;

reading, with a RFID (radio frequency identification) reader embedded in the optical transceiver, data from a RFID device attached to an end of the cable; and

determining, with the data from the optical transceiver and the data from the RFID device, an operational status of the cable.

2. The method of claim 1, wherein the optical transceiver is a small form-factor pluggable and the RFID reader includes an antenna and read circuitry.

3. The method of claim 1 further comprising, monitoring the cable to receive the data from the optical transceiver while fiber optic transmissions are occurring through the cable.

4. The method of claim 1 further comprising, receiving data from a first optical transceiver and a first RFID device at one end of the cable and from a second optical transceiver and a second RFID device at a second end of the cable.

5. The method of claim 1 further comprising, periodically monitoring the cable to receive new data from the optical transceiver and the RFID device.

7. The method of claim 1 further comprising, providing the data from the optical transceiver over a standard protocol that includes one of SNMP (Simple Network Management Protocol) and SMI-S (Storage Management Initiative-Specification).

6. A method, comprising:

reading, with a RFID (radio frequency identification) reader embedded in an optical transceiver, data from a RFID device attached to an end of a fiber optic cable when the end of the fiber optic cable is plugged into the optical transceiver;

receiving data from both the optical transceiver and the RFID device; and

determining, with the data from both the optical transceiver and the RFID device, an operational status of the cable, wherein the data includes laser transmit current, laser transmit optical power, and photodiode optical energy.

8. A computer readable medium having instructions for causing a computer to execute a method, comprising:

reading, with a RFID (radio frequency identification) reader embedded in an optical transceiver, data from a RFID device attached to an end of a cable while the end of the cable is plugged into the optical transceiver;

monitoring the cable to receive data from the optical transceiver coupled to the cable and the RFID device coupled to the cable, the data from the optical transceiver including one of laser information and optical power information; and

diagnosing the data from both the optical transceiver and the RFID device to determine if the cable is properly functioning.

9. The computer readable medium of claim 8, wherein the data from the optical transceiver includes optical transmit power, optical receive power, laser current, and laser type.

10. The computer readable medium of claim 8 further comprising, obtaining the data from a first optical transceiver located at one end of the cable and a second optical transceiver located at another end of the cable.

11. The computer readable medium of claim 8 further comprising, obtaining the data from a first RFID device embedded at one end of the cable and a second RFID device embedded at another end of the cable.

12. The computer readable medium of claim 8 further comprising, collecting a first portion of the data from a first end of the cable and a second portion of the data from a second end of the cable.

13. The computer readable medium of claim 8, wherein the optical transceiver is a small form-factor pluggable.

14. The computer readable medium of claim 8 further comprising, transferring the data from the optical transceiver and the RFID device through a switch to a central management location.

15. The computer readable medium of claim 8 further comprising, using the data to determine if the cable is operating in a degraded condition.

16. A computer system, comprising:

a memory storing instructions; and

a processor executing the instructions to;

receive data from a first small form-factor pluqgable (SFP) coupled to a cable, the data including at least one of laser information and optical power information;

receive data from a first RFID (radio frequency identification) reader located in the first SFP, the first RFID reader reading a RFID device located at the end of the cable; and

determine, with the data from the first SFP and the RFID device, an identity of the cable and whether if the cable is properly operating.

17. The computer system of claim 16, wherein the at least one of laser information and optical power information includes photodiode receiver optical energy and laser wavelength.

18. The computer system of claim 16, wherein the laser information includes laser current and laser type, and the optical power information includes optical transmit power and optical receive power.

19. The computer system of claim 16, wherein the processor further executes the instructions to receive data from a second SFP coupled to the cable and a second RFID reader coupled to the cable.

20. The computer system of claim 16, wherein the processor further executes the instructions to determine when the cable is operating in a degraded condition based on laser transmit power received from the first optical transceiver.
