Precision Optical Low-Coherence Reflectometry for Fiber Testing
Optical Low-Coherence Reflectometry (OLCR) is an advanced testing technique that uses low-coherence interferometry to measure optical path differences and locate faults or structural variations within fiber optic components. Unlike traditional reflectometry, OLCR delivers exceptional spatial resolution and is ideal for characterizing short optical devices or layered structures. At Fiber Optical Test, we provide industry-grade OLCR systems that meet the most demanding inspection requirements. Headquartered in Grand Chute, WI, we’ve earned recognition across North America for delivering highly reliable, forward-thinking fiber testing technologies. Through rigorous R&D, quality assurance, and customer-first service, we empower B2B clients to achieve high-performance diagnostics, increased operational efficiency, and long-term system reliability.
