This article outlines the specific end-face inspection criteria for fiber optic patch cords, focusing on the critical zones defined in the inspection process: Zone A, Zone B, and Zone C. Each zone has distinct criteria for acceptable defects, which we will discuss in detail. Which standard should you follow for endface pass or fail criteria? You should follow IEC 61300-3-35. The International Electrotechnical Commission (IEC) developed the 61300-3-35 standard to guide consistent fiber end face inspection — here we discuss the latest edition, which has some significant changes that can simplify your inspection and cleaning workflow. In fiber connectors, for example, particles or defects at the contact point can raise insertion loss, increase reflectance (reduce. 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.
