Abstract
In some examples, automatic OTDR-based testing may include determining, based on analysis of a signal that is received from a DUT that is to be monitored, whether the DUT is optically connected. Based on a determination that the DUT is optically connected, a measurement associated with the DUT may be performed.
Claims16
An apparatus comprising:
- a device under test (DUT) connection detector, executed by at least one hardware processor, to
- receive a signal from a DUT that is to be monitored,
- analyze a signal level associated with the received signal to determine whether the signal level is greater than a reference level threshold,
- determine, based on the analysis of the signal level, whether the DUT is optically connected in accordance with a connection quality specification, and
- generate, based on a determination that the signal level is greater than the reference level threshold, an indication that the DUT is optically connected;
- and
- an optical reflectometer controller, executed by the at least one hardware processor, to
- perform, based on a determination that the DUT is optically connected, a measurement associated with the DUT.

A method comprising:
- determining, based on analysis of an emitting signal that is received from an Optical Time-Domain Reflectometer (OTDR) that is optically connected to a device under test (DUT) that is to be monitored, whether a first end of the DUT is optically connected to a connection port and a second opposite end of the DUT is optically connected to the OTDR by determining, based on analysis of a signal level associated with the emitting signal to determine whether the signal level is greater than a reference level threshold, whether the DUT is optically connected to the connection port and to the OTDR;
- generating, based on a determination that the signal level is greater than the reference level threshold, an indication that the DUT is optically connected to the connection port and to the OTDR;
- and
- performing, based on the determination that the DUT is optically connected to the connection port and to the OTDR, a measurement associated with the DUT.

A non-transitory computer readable medium having stored thereon machine readable instructions, the machine readable instructions, when executed by at least one hardware processor, cause the at least one hardware processor to:
- determine, based on analysis of a signal that is received from a DUT that is to be monitored, whether the DUT is optically connected in accordance with a connection quality specification by determining, based on analysis of a signal level associated with the signal to determine whether the signal level is greater than a reference level threshold, whether the DUT is optically connected;
- generate, based on a determination that the signal level is greater than the reference level threshold, an indication that the DUT is optically connected;
- and
- perform, based on the determination that the DUT is optically connected, a measurement associated with the DUT.
