HIGH-RESOLUTION OPTICAL REFLECTOMETRY

Abstract

Reflectometers - these are instruments used to measure parameters of various types of optical systems, such as: return loss, insertion loss, location of reflective events in the fiber path. While standard optical reflectometers, time domain (English. Optical Time Domain Reflectometer – OTDR), are widely used in the characterization of medium and long-haul fiber networks, OBR backscatter OTDR, offers a unique combination of high spatial resolution and sensitivity. This makes OBR a very important tool for analyzing the parameters of shorter local, FOCL, components and modern photonic integrated circuits Whether analyzing the performance of a miniature PIC or determining the best troubleshooting method for a long haul fiber optic cable, understanding and quantifying loss along the optical path is a key step
