This paper examines why it is a sound decision to invest in a high-quality, future-proof optical spectrum analyzer and introduces key technical concepts.

As turn-up activities are often prone to errors and inconsistencies, this application note discusses some best practices for turning up WDM networks.

An introduction to one of EXFO's latest innovations to its FTB-5240S/B-P, WDM-Aware. WDM-Aware offers the i-in-band mode—intelligent setups, optimized on a per-channel basis, which delivers accurate test results all automatically, all the time. WDM-Aware removes the uncertainty about test results, removes the guesswork, automates and speeds up tests, and thereby reduces OPEX.

Learn about how modern WDM network operators are faced with new challenges when measuring system performance, namely its OSNR. Gain insight into EXFO's new techniques and patented algorithms that currently being used for OSNR testing in WDM networks.

Troubleshooting is typically initiated due to an alarm received at the network operation center. This application note provides guidelines to allow carriers to rapidly pinpoint the defective component, which is commonly a splice, a connector, an amplifier or a transmitter.

This article presents examples of complex systems and the challenges they present when measuring OSNR and introduces the WDM-aware technology that provides expert-level, automated OSNR measurements optimized on a wavelength basis.

The FTB-5240S/B-P now features WDM-Aware technology, which offers the i-in-band mode—intelligent setups, optimized on a per-channel basis, delivering accurate test results all automatically, all the time. See how you can redefine WDM testing and network optimization, and make complex network activation child's play.

As bandwidth demand continues to increase, NSPs are looking at 40G/100G networks to accommodate the ongoing traffic surge. Watch this animated diagram to see how EXFO’s 40G/100G know-how encompasses network component and fiber testing throughout all the transmission network stages to ensure seamless wireline and wireless network infrastructure upgrades.

With the growing demand for 100G services, and the greater capacity and bandwidth that they require, networks are becoming increasingly complex. This animated diagram shows you how EXFO can help you meet 100G Ethernet testing challenges, in the lab and in the field.

The FTB-5240S/BP are highly accurate OSAs for current and next-generation networks, covering your DWDM applications and all channel spacings, from 50 GHz DWDM to CWDM.

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

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 the system.

This application note presents the second configuration, explaining how and why such a test should be performed.

This application note covers the main testing issues when using reconfigurable optical add/drop multiplexers (ROADMs) to better provision DWDM services across metropolitan Ethernet networks.

This application note discusses in-band optical signal-to-noise ratio (OSNR) testing, more specifically when there are several ROADMs in a network.

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 describes the requirements and challenge that providers may face when deploying new modulation rates (40 Gbit/s and 100 Gbit/s) on existing networks.

This article provides an overview of ROADM-based networks, used to efficiently and cost-effectively transmitting various data types over a common network infrastructure.

This article explains why a next-generation OSA, based on a technique known as polarization-resolved optical spectrum OSNR (PROS OSNR), is required for accurate in-band OSNR measurements.

This paper introduces the concept of OSNR and its importance, as well as the consequences of poor OSNR on a network; it also examines the current perception of OSAs in the marketplace.

This article introduces the polarization-resolved optical spectrum OSNR measurement method, a breakthrough approach that represents a powerful tool for the measurement of in-channel OSNR.

The exponential growth in Internet traffic and related drive for increased capacity introduce network complexities that necessitate advanced test solutions. This flyer presents NSPs with a complete, integrated 40G testing solution that enables them to meet their 40G rollout challenges, both from an infrastructure and service-provisioning standpoint.
