As system and cable installers try to optimize their links, the preferred method has become high-speed DWDM. This demand for bandwidth has led to the development of new test and measurement instruments. Outside plant (OSP) customers and even component and fiber manufacturers are now looking for instruments that deliver laboratory-quality results and are still portable and rugged enough. The wide-scale deployment of DWDM systems with high fiber counts and closely spaced channels has sped the development of a new generation of more powerful optical spectrum analyzers (OSAs). OSAs ensure...Read full article
