Upon completion of the fiber optic installation, the selected vendor must test all single mode fiber at 1310nm and 1550nm wavelengths with an Anristu CMA-4500 Optical Time-Domain Reflectometer
The AQ7280 portable optical time-domain reflectometer
(OTDR) delivers the combination of measurement automation, user-friendly operation, and reliable performance that enables fast, precise optical-fiber characterization in the field.
has launched software upgrades for their CT100 Series Time-Domain Reflectometer
(TDR) cable testers and bundled CT Viewer(TM) TDR analysis software that add real-time Internet streaming and remote control for leverage of remote engineering expertise.
The TDR 100 is a time-domain reflectometer
for measuring volumetric water content and bulk electrical conductivity in soil and other porous media.

This (Army Engineer Waterways Experiment Station) report concerns the development, construction, and testing of a rugged self-calibrating time-domain reflectometer
(TDR) instrument for monitoring groundwater elevations.
If your cable is installed in a ceiling or floor that is hard to get at, using a time-domain reflectometer
can speed the process of locating faults.
It also includes new diagnostic and fault-location equipment, as well as information on digital multimeters, time-domain reflectometers
, meggers and procedures for using the Eclypse ESP+ and 3M 900AST fault-location meters.
