Standards such as IEC 61300-3-47, Basic test and measurement procedures for end face geometry of PC/APC spherically polished ferrules using interferometry, and a series of IEC 61755 standards covering angle polishing, ferrule geometry, materials, and other connector parts . Standards such as IEC 61300-3-47, Basic test and measurement procedures for end face geometry of PC/APC spherically polished ferrules using interferometry, and a series of IEC 61755 standards covering angle polishing, ferrule geometry, materials, and other connector parts . Fiber Chek is an integrated hardware/ software package engineered with the single purpose of critically and consistently grading fiber end-faces. Works hand in hand with the Quick Capture Analog Probe for visual inspection, taking pictures and testing fibers. The GBS1001 inspection probe features a. It's crucial to inspect, clean, and reinspect fiber end faces before mating connectors — whether on patch cords and trunks within the network or on the test reference cord you connect to your tester.
