Fiber Optic Patch Cord End Face Inspection Process
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.

A rubber ring appears on the end face of the fiber optic patch cord
Haloing is a contamination defect that appears on fiber optic end face connections. If present, using a fiberscope to inspect an end face will reveal a discolored ring usually midway between the fiber core and the leading edge of the chamfer. Knowing what each zone means and why the rules tighten as you approach the core is the difference between passing inspection and shipping a connector that will fail in. 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. Contaminated fiber end faces can cause signal loss and reflections that degrade network. To evaluate the quality of optical fiber connectors, it is necessary to measure the shape parameters of the connector pin body end face after grinding and polishing, including three important parameters: radius of curvature, vertex offset and core depression. Each zone has distinct criteria for acceptable defects, which we will discuss in detail. There is some debate about the necessity of removing the.
