One of the questions that typically echoes around tradeshows and conferences is how a Nanalysis instrument compares to high-field data. There are considerable intrinsic differences between low-field ...

The primary limiting factor in transmitting very high data rates on fiber-optic cable is signal dispersion. Dispersion is the lengthening of a pulse over distance due to the variation of the speed of ...

Bringing new efficiencies to high-speed-optical-communications applications continues to challenge scientists and engineers alike. Whenever they overcome the current set of challenges, the demand for ...

Long ago, verifying the performance of a digital communications system was straightforward. The entire network was installed and owned by a single company, and if the system worked, extensive testing ...
