This article discusses the need to measure PMD values to the femtosecond range and how to achieve this by performing complete analysis of polarization states.

This article discusses EXFO's implementation of the Bellcore OTDR format, which offers the advantage of being able to build a database with test results from different OTDR manufacturers.

This article explains the two main methods of measuring chromatic dispersion, the pulse-delay method and the phase-shift method.

This article provides an overview of TFF WDM technology that could be simplest means of performing wavelength division multiplexing.

This paper demonstrates how measuring the total multiplath interference dispersion (MPID) is in many ways a significant advantage over pure PMD-measuring methods, particularly for testing components s...

This technical note provides some experimental results and a few design rules to adequately address the Raman scattering problem.

This application note explores the need to evaluate or re-evaluate not only how network testing is performed, but also what is being tested to ensuring the proper timing of a SONET/SDH network.

This technical note provides an overview of Gigabit Ethernet, positioned to be a key technology in LAN, access, metro, and long-haul network deployments.

This article introduces the EXFO Radiometer, which drastically reduces the measurement inaccuracies caused by filter transmission limitations and the effects of measurement geometry found in other rad...
