Abstract: An apparatus for determining optical fiber array polarity is disclosed. The apparatus may be used to determine optical signal loss or intensity. An adapter may be used to couple the apparatus to a variety of optical fiber connectors. The apparatus includes a position sensing detector and processing circuitry. The position sensing detector includes a sensor that receives optical signals and electrodes that output respective output signals in response to receipt of an optical signal. The processing circuitry receives the output signals and identifies locations at which the optical signals were incident on the sensor. The processing circuitry also determines the receiving position in the optical array of an optical fiber and a polarity of the optical array based on the receiving position and a corresponding transmitting position. The processing circuitry may determine an intensity or loss of the optical signal based on an aggregate of the output signals.

Abstract: A system for certifying physical parameters of fiber optic cabling may include a test device coupled to an end of a fiber optic cable. The test device injects light into the fiber optic cable and conducts a certification test of physical parameters of the fiber optic cable. Based on observation of interaction of the injected light with the fiber optic cable, the test device tests one or more physical parameters of the cable and certifies whether the tested parameters satisfy corresponding parameters specified by a predetermined standard. A separate device may communicate a control signal (e.g., wirelessly) to the test device for controlling an operation of the certification test. The separate device is further operable to receive a result of the certification test from the test device. The separate device may further communicate with a remote computing device updates a database element with information regarding the certification test.

Abstract: Apparatus and methods for testing network cabling includes processing circuitry that receives an indication of a user-selected network test of a plurality of network tests. The respective network tests have respective sets of test requirements with different levels of rigor. The test circuitry conducts a wire map test to identify which network tests can be conducted. Thereafter, a common set of test results is produced based on measurement of a common set of parameters pertinent to the network tests that can be conducted. The processing circuitry evaluates the common set of test results with respect to the respective sets of test requirements to determine one or more passing network tests. A plurality of test reports corresponding to the plurality of network tests is graphically displayed along a curve having a common center, wherein each test report indicates whether the corresponding network test is a passing network test.

Abstract: A display apparatus for optical fiber inspection includes a processor programmed to receive, from a camera, a visual image of an array of endfaces of fiber optic cables being inspected, and to produce, on a display, an inspection interface that includes a first section and a second section. The first section shows a portion of the received image that includes a portion of the endfaces captured in the image. The second section shows a graphical map containing icons that depict representations of the endfaces in the array of endfaces. A selection window identifies the icons representing the endfaces that are currently shown in the first section. In response to user input, the display apparatus correspondingly modifies which endfaces are shown in the first section and modifies the position and/or size of the selection window in the second section.

Abstract: An optical testing device is provided. The testing device includes a position sensing detector (PSD) having an optical sensing area that is optically responsive to a first range of wavelengths. The PSD receives a plurality of optical signals having wavelengths within the first range and emitted through a respective plurality of optical fibers and detects a plurality of positions where the optical signals impinged on the optical sensing area for determining array polarity. The PSD receives a plurality of first optical signals having wavelengths within the first range and detects the polarity and a plurality of optical intensities of the first optical signals. The testing device includes a photodetector that is optically responsive to a second range of wavelengths different than the first range. The photodetector receives a plurality of second optical signals within the second range and detects a plurality of optical intensities of the second optical signals.

Abstract: A test instrument provides suggested next operational step function to provide a user with assistance during testing. A display is provided to show the amount of a project that has been completed, for example as a percentage completed value. Individual test results may be saved to a ‘fix later’ list, which may be later accessed to re-test items that may not have passed on initial testing.

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.
