An OTDR (Optical Time Domain Reflectometer) is a measuring instrument intended to measure the transmission loss and distance of optical fibers, locate cable cuts, and evaluate the connection loss and reflectance (return loss) of fusion splices, mechanical splices, connector connections, etc. Also. The Anritsu embedded OTDR series is designed to integrate industry leading OTDR technology into any standard PCI connector. Our high resolution, high dynamic range test systems are ideally suited for both short and long haul testing or monitoring applications. They are available in several. This paper describes fundamental knowledge about an optical time domain reflectometer (OTDR), such as operation mechanism, various technical specifications, how to use an OTDR, and notices in an OTDR use case.

Several wavelength and dynamic range combinations are available as well as VFL, powe meter, light source and PON power meter functions. The MT9090A is a modular platform that can be configured as an optical fault locator, general purpose OTDR. This manual helps you understand how an OTDR characterizes optical fibers, finds defects and faults, and determines signal loss.
