    Abstract: An integrating sphere-equipped optical measurement device and optical connector polarity and type identification and loss measurement are provided. The optical measurement device includes at least two photodetectors that are optically responsive over different ranges of wavelengths. The optical measurement device receives one or more optical signals emanate from optical fibers of an optical fiber cable. The optical measurement device determines an optical intensity or loss of the one or more optical signals based on a measurement made by a corresponding photodetector whose responsivity range includes a wavelength of the one or more optical signals. The optical measurement device determines one or more respective positions where the one or more optical signals impinged on a sensor. The optical measurement device determines a polarity of the optical fiber cable based on both the one or more positions and one or more or transmitting positions of the one or more optical signals, respectively.

    Abstract: A self-contained calibration method for improving stability of an optical source in an optical network test instrument includes performing a temperature sweep test of the optical source. Optical output power of the optical source is periodically measured. A temperature correcting value is generated based on the measured optical output power. The optical output power of the optical source is adjusted by applying the temperature correcting value to obtain a substantially constant optical output power of the optical source.

    Abstract: A system for testing an optical fiber includes an optical source apparatus and an optical image sensor apparatus. The optical source apparatus includes a fiber optic connector that connects to a first end of the fiber, and a light emitting device which emits light into the first end of the fiber. The optical image sensor apparatus includes a fiber optic connector that connects to a second end of the fiber, an image sensor that receives light output from the second end of the fiber and generates corresponding image data, a lens array in an optical path between the fiber optic connector and the image sensor, and a processor coupled to the image sensor. The processor, in operation, determines a set of two-dimensional positions based on the image data output from the image sensor, and determines a test result based on the set of two-dimensional positions.

    Abstract: A system and method for aggregation of test result data includes a plurality of first testing devices configured to perform testing procedures to test cables of at least one communication network and to output associated first test result data. A cloud-based server device is coupled via a network to the plurality of first testing devices. The server device includes a database configured to store the first test result data and a processor. The processor is configured to determine a statistic associated with an aggregation of the first test result data output by the plurality of first testing devices. Second test result data is then received by the processor from a second testing device so as to be compared to the determined statistic and to output an indication of a result of the comparison.

    Abstract: One or more embodiments are directed to optical test instruments, such as fiber optic inspection scopes and optical power meters, for testing optical communication links, such as fiber optic connectors. The optical test instruments include a single test port that is able to operate in two modes of operation. In a first mode of operation, the optical test instrument is configured to provide an image of the endface of a fiber optic connector under test. In a second mode of operation, the optical test instrument is configured to measure power or power loss in an optical fiber under test. In that regard, the fiber optic connector only has to be coupled to a single port of an optical test instrument for a visual inspection of an endface of a fiber optic connector and a power test of the optical fiber under test.
