Abstract
The technologies described herein are generally directed to using a loopback component to test a single fiber optic strand. For example, a method described herein can include generating a first optical beam of a first wavelength. The method can further include transmitting the first optical beam via a fiber optic fiber. Further, the method can include receiving via the fiber optic fiber, a second optical beam of a second wavelength, with the second optical beam having a characteristic of the first optical beam, and with the second optical beam being generated by a non-electrical conversion of the first light of the first wavelength to the second light of the second wavelength
Claims20
A method, comprising:
- generating, by network equipment comprising a processor, a first optical beam, wherein the first optical beam comprises first light of a first wavelength;
- transmitting, by the network equipment, the first optical beam via a fiber optic fiber;
- and
- receiving, by the network equipment, via the fiber optic fiber, a second optical beam comprising second light of a second wavelength comprising a characteristic of the first optical beam, wherein the second optical beam was generated by combining the first light of the first wavelength with a third light of the second wavelength and filtering the first light from the third light, resulting in the second light of the second wavelength comprising the characteristic of the first optical beam.
An optical loopback system, comprising:
- a signal receiver that facilitates reception, via a fiber optic medium, of a first light signal corresponding to a first wavelength;
- a light signal combiner that combines the first light signal with a second light signal to generate a combined light signal, wherein the second light signal corresponds to a second wavelength different from the first wavelength, and wherein the combining modifies a characteristic of the second light signal based on the first light signal, resulting in a modified characteristic of the second light signal;
- and
- a filter that eliminates the first light signal from the combined light signal to generate a third light signal, wherein the modified characteristic of the second light signal is able to be tested to assess a performance of the fiber optic medium.
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving, via a fiber optic cable, a first fiber optic signal comprising a first wavelength;
- combining the first fiber optic signal with a second fiber optic signal to generate a combined fiber optic signal, wherein the second fiber optic signal comprises a second wavelength different from the first wavelength, and wherein the combining modifies a characteristic of the second fiber optic signal based on the first fiber optic signal, resulting in a modified characteristic of the second fiber optic signal;
- and
- filtering to remove the first fiber optic signal from the combined fiber optic signal to generate a third fiber optic signal, wherein a result of assessing the modified characteristic of the second fiber optic signal is usable to assess a performance of the fiber optic cable.
