Type: Singleeye monocular handheld fiber optic microscope, magnifier, and fiber endface detector. Magnification: Commonly 200x and 400x. Core function: Quickly detects dents and scratches on FC, SC, and ST type fiber jumpers/pigtails (male). Produces a clear fiber endface image with a wellcentered view for reliable inspection. Endface detection: Capable of inspecting PC endfaces and APC endfaces. Benefits and why you need it: Enables fast, accurate visual assessment of fiber connector end faces, helping identify defects before installation or after fieldwork. Enhances quality control in manufacturing, installation, and maintenance workflows. Portable handheld design supports onsite usage without bulky equipment. Compatibility and performance: Works with common FC/SC/ST male fiber jumpers and pigtails. Delivers clear imaging at 200x and 400x to reveal surface flaws and alignment issues. Size and materials: Compact handheld instrument designed for oneeye use; built for convenient portability and quick inspections in the field or workshop. Material details are not specified in the product description. Use scenarios and applications: 1) Onsite fiber installation and maintenance: rapidly check jumper end faces for dents, scratches, or misalignment before mating connectors. 2) Manufacturing quality control: inspect PC and APC endfaces during production to ensure connector integrity and performance. 3) Field troubleshooting in optical networks: verify endface condition to diagnose connectivity issues and reduce downtime.
