Abstract

A method for providing tests and measurements using a transceiver is disclosed. In some examples, the method may involve using, at least one test instrument and at least one transceiver, to perform tests and measurements at a testing point in a network. The tests and measurements may include at least one of: (1) channel or wavelength and data measurements; (2) insertion loss and optical power measurements; or (3) bit error rate (BER) measurements.

First claim

The invention claimed is:

1. A method, comprising:
connecting a test instrument and at least one transceiver to an end of a fiber optic link of a network;
transmitting, by the at least one transceiver, a test signal in the fiber optic link of the network and receiving, by the test instrument and the at least one transceiver, a return of the test signal in a first channel of the fiber optic link of the network;
determining, by the test instrument, a signal power associated with the returned test signal;
identifying, by the test instrument, one or more open channels near or around the first channel that contained the returned test signal; and
displaying, on a display element of the test instrument, available wavelengths of the one or more open channels near or around the first channel and the signal power associated with the returned test signal.

2. The method of claim 1 , wherein the at least one transceiver is plugged into a port of the test instrument.

3. The method of claim 2 , wherein the at least one transceiver comprises a T2DOC™ or FlexTune™ transceiver.

4. The method of claim 1 , further comprising:
connecting another transceiver and another end of the fiber optic link of the network, wherein the another transceiver is to receive the test signal from the at least one transceiver and transmit the returned test signal to the at least one transceiver.

5. The method of claim 1 , further comprising:
measuring, by the test instrument, at least one of: insertion loss, temperature, or bit error rate (BER) based on the returned test signal.

6. The method of claim 5 , further comprising:
displaying results from the measuring of at least one of the insertion loss, the temperature, or the BER on the display element of the test instrument.

7. A non-transitory computer-readable storage medium storing instructions, which, when executed by a processor of a test instrument, cause the processor to:
connect the test instrument and at least one transceiver to an end of a fiber optic link of a network;
transmit a test signal from the at least one transceiver to the fiber optic link of the network;
receive, by the test instrument and the at least one transceiver, a return of the test signal in a first channel of the fiber optic link of the network;
determine, by the test instrument, a signal power associated with the returned test signal;
identify, by the test instrument, one or more open channels near or around the first channel that contained the returned test signal; and
display, on a display element of the test instrument, available wavelengths of the one or more open channels near or around the first channel and the signal power associated with the returned test signal.

8. A test instrument, comprising:
a processor communicatively coupled to at least one transceiver; and
a memory storing instructions, which when executed by the processor, cause the processor to:
connect the test instrument and at least one transceiver to an end of a fiber optic link of a network;
transmit a test signal from the at least one transceiver to the fiber optic link of the network;
receive, by the test instrument and the at least one transceiver, a return of the test signal in a first channel of the fiber optic link;
determine, by the test instrument, a signal power associated with the returned test signal;
identify, by the test instrument, one or more open channels near or around the first channel that contained the returned test signal; and
display, on a display element of the test instrument, available wavelengths of the one or more open channels near or around the first channel and the signal power associated with the returned test signal.

9. The test instrument of claim 8 , wherein the at least one transceiver is plugged into a port of the test instrument.

10. The test instrument of claim 8 , wherein the at least one transceiver comprises a T2DOC™ or FlexTune™ transceiver.

11. The test instrument of claim 8 , wherein the instructions further cause the processor to:
connect another transceiver and another end of the fiber optic link of the network, wherein the another transceiver is to receive the test signal from the at least one transceiver and transmit the returned test signal to the at least one transceiver.

12. The test instrument of claim 8 , wherein the instructions further cause the processor to:
measure, by the test instrument, at least one of insertion loss, temperature, or bit error rate (BER) based on the returned test signal.

13. The test instrument of claim 12 , wherein the instructions further cause the processor to:
display results of the measuring of at least one of the insertion loss, the temperature, or the BER on the display element.

14. The test instrument of claim 8 , wherein the display element comprises at least one of a liquid crystal display (LCD), a light emitting diode (LED) display, or a touchscreen display.
