Abstract:
The invention is a fiber optic cable calibration standard in combination with a device for calibrating distance and attenuation parameters of an optical time domain reflectometer (OTDR). The calibration standard includes a fiber optic cable spool assembly and inspection apparatus. The invention is also a calibration method. An OTDR to be calibrated against a National Institute of Standards and Technology (NIST) standard.
