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.

Display screen or portion thereof with graphical user interface

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.

Display screen or portion thereof with graphical user interface for fiber optic cable inspection

A testing device which includes a testing unit to perform test procedures on network elements of a communication network and a machine-readable code reader to read a machine-readable code associated with a network element of the communication network. The testing device further includes a computer device configured to: (i) determine a component type associated with the machine-readable code data read; (ii) select from a plurality of configuration files a configuration file based on the component type determined; and (iii) configure the test unit for a test procedure using the configuration file selected, and to perform the test procedure on the network element.

System and method for utilizing machine-readable codes for testing a communication network

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.

Display apparatus and method for optical fiber inspection

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.
