Bi-Lateral Comparison between NIS-Egypt and NMISA-South Africa for the Calibration of an Optical Time Domain Reflectometer
نویسندگان
چکیده
Calibration of Optical Time Domain Reflectometer (OTDR) has a crucial role for the accurate determination of fault locations and the accurate calculation of loss budget of long-haul optical fibre links during installation and repair. A comparison has been made between the Egyptian National Institute for Standards (NIS-Egypt) and the National Metrology institute of South Africa (NMISA-South Africa) for the calibration of an OTDR. The distance and the attenuation scales of a transfer OTDR have been calibrated by both institutes using their standards according to the standard IEC 61746-1 (2009). The results of this comparison have been compiled in this report. Keywords—OTDR calibration, recirculating loop, concatenated method, standard fibre.

Development of a Symmetric Ring Junction as Four-Port Reflectometer for Complex Reflection Coefficient Measurements
Six-port reflectometer is well-known for its ability to measure magnitude and phase-shift of microwave signal using four power detectors that perform magnitudeonly measurements. This paper presents the development of an innovative symmetric ring junction as four-port reflectometer for complex reflection coefficient measurements. It reduces the number of required detectors to two. Design optimiz...
متن کاملA new robust method for six-port reflectometer calibration
A new robust method for finding the parameters of Engen’s six-port-to-four-port reduction algorithm for sixport reflectometer calibration has been developed. Like other previously published methods, it uses a minimum of five loads with an unknown but constant absolute value of the reflection coefficient and unknown but well-distributed phases. However, the quality of the parameter estimates is ...
متن کاملIn situ measurement of soil moisture: a comparison of techniques
A number of automated techniques for point measurement of soil moisture content have been developed to an operational level over the past few decades. While each of those techniques have been individually evaluated by the thermogravimetric (oven drying and weighing) method, typically under laboratory conditions, there have been few studies which have made a direct comparison between the various...
متن کاملA new method for automatic calibration of 5-port reflectometers
The five-port reflectometer has been recently applied to demodulators and radars, offering an alternative to classic In-Phase/In-Quadrature (I/Q) discriminators. In these applications, calibration of the reflectometer is an important task. Most of the methods developed are suitable for the instrumentation and measurement field and present a high degree of complexity. We propose in this paper a ...
متن کاملCompact soft x-ray reflectometer based on a line-emitting laser-plasma source
We describe a compact soft x-ray reflectometer for in-house characterization of water-window multilayer optics. The instrument is based on a line-emitting, liquid-jet, laser-plasma source in combination with angular scanning of the studied multilayer optics. With a proper choice of target liquid and thin-film filters, one or a few lines of well-defined wavelength dominate the spectrum and multi...
