The OBR 4400 takes the industry's first ultra-high resolution OTDR with backscatter-level sensitivity designed for component- and module-level reflectometry to the next level. With a small, easily transportable platform, the capability to "see" reflections out to 2 kilometers with no dead zone, and integrated temperature and strain sensing, the OBR 4400 gives you the ultimate in fiber diagnostics. The OBR 4400 uses swept-wavelength coherent interferometry to measure minute reflections (< 0.0003 parts per billion) in an optical system as a function of length with spatial resolution less than 50 microns. This provides the user with precision reflectometry and unprecedented optical-module inspection and diagnostic capabilities by providing the ability to locate and troubleshoot splices, connectors suppliers, fiber bends and breaks, insertion loss points, track polarization, verify PM components and more.
