This application note reviews the critical parameters (and the order in which they should be tested) and the general criteria for quality transmission.

This article demonstrates how OSNR can be derived, for each individual channel, from an optical spectrum measurement to obtain indirect information about the performance of these channels and hence of...

This application note focuses on the possible approaches to dealing with excess PMD and highlights the preferred one, from a cost-effective standpoint.

This application note explains why it is essential to analyze not only the circuit ofinterest, but the environment around the circuit when testing services.

This application note highlights the differences between the differential phase-shift method and the phase-shift method.

This application note demonstrates how linearity at the far end of an OTDR trace is very important to guarantee proper link loss, event loss and attenuation readings.

This article demonstrate how the IQS-500 Intelligent Test System can be integrated into your own test setup to meet the requirements of automation.

This application note is intended to provide guidance for proper testing methods for SONET-based networks as recommended by EXFO.

This article provides key information on portable optical spectrum analyzers (OSAs) and how they can measure the most important parameters in a DWDM system.
