Optical Time Domain Reflectometry

    0.01 sec.
Optical Time Domain Reflectometry - Measurement of the elapsed time and intensity of light reflected on optical fibre using an optical time domain reflectometer. The reflectometer can compute the distance to problems on the fibre such as attenuation and breaks, making it a useful tool in optical network trouble-shooting.

The sensors operate on the optical time domain reflectometry (OTDR) principle, invented by Barnowski and Jensen in 1976, which was the first method for distributed fibre measurements using backward Rayleigh scattering to determine the optical loss along fibres [19].
The business provides flexible and easy to use tools for loss, dispersion, PMD, polarization, high-resolution Optical Time Domain Reflectometry, and distributed temperature and strain analysis for optical fiber components, modules and networks.
