Abstract
In some examples, OTDR event detection and light power level measurement-based fiber optic link certification may include performing, at one end of a device under test (DUT) of a network, a light power level measurement. An OTDR measurement may be performed at the one end of the DUT to detect at least one event associated with the DUT. Based on analysis of the light power level measurement and the OTDR measurement, an event classification may be generated to classify the at least one event associated with the DUT.
Claims16
An apparatus comprising:
- a power meter, executed by at least one hardware processor, to perform, at one end of a device under test (DUT) of a network, a light power level measurement;
- an optical time-domain reflectometer (OTDR) event detector, executed by the at least one hardware processor, to perform, at the one end of the DUT, an OTDR measurement at a relatively short pulse width and at a relatively long pulse width to detect at least one event associated with the DUT;
- and
- an event classifier, executed by the at least one hardware processor, to generate, based on analysis of the light power level measurement and the OTDR measurement at the relatively short pulse width and at the relatively long pulse width, an event classification to classify the at least one event associated with the DUT.
A method comprising:
- performing, by at least one hardware processor, at one end of a device under test (DUT) of a network, a light power level measurement;
- performing, by the at least one hardware processor, at the one end of the DUT, an optical time-domain reflectometer (OTDR) measurement at a relatively short pulse width and at a relatively long pulse width to detect at least one event associated with the DUT;
- and
- generating, by the at least one hardware processor, based on analysis of the light power level measurement and the OTDR measurement at the relatively short pulse width and at the relatively long pulse width, an event classification to classify the at least one event associated with the DUT.
A non-transitory computer readable medium having stored thereon machine readable instructions that, when executed by at least one hardware processor, cause the at least one hardware processor to:
- perform, at one end of a device under test (DUT) of a network, a light power level measurement;
- perform, at the one end of the DUT, an OTDR measurement at a relatively short pulse width and at a relatively long pulse width to detect at least one event associated with the DUT;
- and
- generate, based on analysis of the light power level measurement and the OTDR measurement at the relatively short pulse width and at the relatively long pulse width, an event classification to classify the at least one event associated with the DUT.
