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

This article explains how users can acquire information about the transmitted signal that would not have been able to obtain, such as the probability of error of each individual bits/bytes in a patter...

In this article, EXFO demonstrates its innovation in applying its CWDM OTDR technology to fiber-monitoring application.

This application note discusses two of the main aspects of fiber certification; namely, industry standards and light source launch conditions.

This application note exposes some of the limitations of copper testers when it comes to testing fiber-optic links and outlines the reasons why true fiberoptic test instruments should be preferred.

This articles discusses how to maximize network availability and efficiency, and improve customer QoS through centralized, integrated network performance and service-management processes.

This application note presents the two basic test setups that can be used for the Packet Blazer/ENIU combination: the RFC 2544 test and the frame analyzer/generator test.

With the ever-increasing bandwidth demand, operators must radically boost network capacity, while pursuing the equally vital objective of cutting back on OPEX.
