IEC 60793-1-48: 2017 Published for Optical Fibres – Polarization Mode Dispersion

Untitled-5

The International Electrotechnical Commission (IEC) has released IEC 60793-1-48: 2017. This standard pertains to optical fibres, specifically measurement methods and test procedures – Polarization mode dispersion.” This standard is now available on the IEC webstore.

Description: “IEC 60793-1-48: 2017 applies to three methods of measuring polarization mode dispersion (PMD), which are described in Clause 4. It establishes uniform requirements for measuring the PMD of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes.

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.

This third edition cancels and replaces the second edition published in 2007. It constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: removal of the SOP approach.”
