Abstract

A device for processing data being optically transmitted via a LRM connection includes an optical splitter for splitting an input signal into a first output signal and a second output signal, the optical splitter having an operating wavelength with a value that is between 1260 nm and 1355 nm, wherein the optical splitter has an input end for receiving the input signal, a first output end for outputting the first output signal, and a second output end for outputting the second output signal.

Claims (37)

1. A device for processing data being optically transmitted via a LRM connection, comprising:

an optical splitter for splitting an input signal into a first output signal and a second output signal, the optical splitter having an operating wavelength with a value that is between 1260 nm and 1355 nm, wherein the optical splitter has an input end for receiving the input signal, a first output end for outputting the first output signal, and a second output end for outputting the second output signal, and wherein the optical splitter is configured to be relatively more sensitive to a light signal at the operating wavelength with the value that is between 1260 nm and 1355 nm than a light signal at another wavelength;

a first output port;

a second output port; and

an additional optical splitter;

wherein the first output end of the optical splitter is coupled to the first output port for transmitting the first output signal out of the device; and

wherein the additional optical splitter is configured to receive an additional input signal, and split the additional input signal into a third output signal and a fourth output signal, the additional optical splitter being coupled to the second output port for transmitting the third signal out of the device.

2. The device of claim 1 , wherein the LRM connection comprises a 10GBASE-LRM connection.

3. The device of claim 1 , further comprising an optical receiver optically coupled to the second output end of the optical splitter.

4. The device of claim 3 , wherein the optical receiver has an operating wavelength with a value that is between 1260 nm and 1355 nm.

5. The device of claim 3 , wherein the optical receiver and the optical splitter are mounted to a board.

6. The device of claim 3 , wherein the second output end of the optical splitter is coupled to an optical port at a side of a housing, and the optical receiver is optically coupled to the second output end via the optical port.

7. The device of claim 3 , further comprising a processor coupled to the optical receiver.

8. The device of claim 7 , wherein the processor is configured to perform a process selected from the group consisting of data duplication, intrusion detection, network analysis, and network monitoring.

9. The device of claim 7 , wherein the processor and the optical splitter are mounted to a board.

10. The device of claim 7 , wherein the optical receiver is coupled to a port at a side of a housing, and the processor is coupled to the optical receiver via the port.

11. The device of claim 1 , wherein the optical splitter is configured to provide a predetermined split ratio.

12. The device of claim 11 , wherein the predetermined split ratio is 10/90, 20/80, 30/70, 40/60, or 50/50.

13. The device of claim 1 , further comprising:

a housing for accommodating the optical splitter; and

an input port coupled to the input end of the optical splitter.

14. The device of claim 7 , wherein the processor is configured to perform data duplication, intrusion detection, sessions capturing across parallel links and switches, data filtering, data flow configuration, or load division across multiple tools.

15. A method for processing data being optically transmitted, comprising:

optically receiving an input signal that is being transmitted via a LRM connection;

splitting the input signal into a first output signal and a second output signal using an optical splitter, the optical splitter having an operating wavelength with a value that is between 1260 nm and 1355 nm, wherein the optical splitter is configured to be relatively more sensitive to a light signal at the operating wavelength with the value that is between 1260 nm and 1355 nm than a light signal at another wavelength;

outputting the first output signal, wherein the first output signal is output to a first output port of a device;

outputting the second output signal;

optically receiving an additional input signal;

splitting the additional input signal into a third output signal and a fourth output signal using an additional optical splitter; and

outputting the third output signal from the additional optical splitter to a second output port of the device.

16. The method of claim 15 , wherein the LRM connection comprises a 10GBASE-LRM connection.

17. The method of claim 15 , wherein the first output signal is output so that it is passed downstream towards an intended recipient.

18. The method of claim 15 , further comprising processing the second output signal.

19. The method of claim 18 , wherein the second output signal is processed to perform a function selected from the group consisting of data duplication, intrusion detection, network analysis, and network monitoring.

20. The method of claim 15 , wherein the input signal is split based on a predetermined split ratio.

21. The method of claim 20 , wherein the predetermined split ratio is 10/90, 20/80, 30/70, 40/60, or 50/50.

22. The method of claim 15 , wherein the second output signal is processed to perform data duplication, intrusion detection, sessions capturing across parallel links and switches, data filtering, data flow configuration, or load division across multiple tools.
