Luna Technologies, a division of Luna Innovations Inc., has launched the Optical Backscatter Reflectometer 4200, a portable ultrahigh-resolution device offering advanced inspection and diagnostic capabilities to manufacturers and installers of fiber optic assemblies and short networks. The company says it produces 1000 times higher resolution than an optical time-domain reflectometer and is highly sensitive. The device achieves 0.1-dB insertion loss resolution and can identify nonreflective failures. It operates at 1540 nm with single- and multimode capability, and it includes a customizable software interface. Applications include total fiber system quality control to ensure component performance and network uptime; insertion and return loss verification for fiber cables, connections, components and splices; and high-resolution fault location and failure analysis to determine bend, break, bad splice and bad connector points.

An instrument for measuring reflectance.
1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
A permanent joint whose purpose is to couple optical power among two or more ports. Also, a device whose purpose is to couple optical power between a waveguide and a source or detector.
