This article presents a cost-effective solution for operators who transmit over fibers exhibiting high PMD, allowing them to upgrade parts of their high-dispersion fiber links, prior to upgrading thei...

This application note explores some key elements and measurement techniques specific to PON that are used by the PPM-350 Series to obtain the most accurate results.

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

This application note provides an overview of the basic concepts of PMD and the impact that strong-mode and weakmode coupling have on PMD testing; the accuracy of test instruments will also be discuss...

This application note answers the top 10 questions one should ask before deploying SBCs.

This application note explores effective approaches for measuring noise and used by service providers who are determined to ensure quality of service (QoS) to their customers.

This application note explores technologies driving the evolution to higher-bandwidth networks: the ROADM technology and the optical transport network (OTN) standard.

This application note explores the fundamental OTDR principles that are key to understanding the specifications of this instrument.

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.
