在当今竞争日益激烈的市场上，全球各地的电信和网络运营商正努力提供住宅、移动和企业服务所需的带宽，并将网络升级至40G/100G。了解我们的40G/100G产品系列，获得加快上市周期、节约成本并提供高速服务所需的工具。

本文介绍了为何40 Gbit/s技术会需要更严格的测试，并将重点放在熔接连接而不是连接器上，以防止不必要的功率损耗，并将MPI的影响降至最低水平。

This webinar discusses the testing and validation processes necessary to overcome new challenges presented by high-speed 40 Gbit/s networks.

This webinar explores the essential role of chromatic dispersion (CD) and polarization mode dispersion (PMD) in characterizing next-generation 40 Gbit/s transmission links.

In this webinar, we discuss the importance of OSNR, the impacts of poor OSNR on a network, and we introduce EXFO’s approach to accurately measure OSNR in 40G and ROADM networks.

This webinar reviews possible methods and tools to achieve fast and accurate testing of 100G transmitters during manufacturing. More specifically, it presents a novel approach allowing the use of masks to avoid the need to interpret the test results. As this webinar is hosted by a third party, you will be redirected to their website to listen to the recording.

本文将说明相移法，这是一种更常用及标准的色度色散测量技术，对光进行正弦强度调制。

本文将介绍第二种配置，解释如何及为什么进行这种测试。

本文将描述EXFO如何使用安装在欧洲的PMD和CD分析仪，以及位于加拿大的光源（FLS-5803），测试跨大西洋网络的PMD和CD。

本文简述了差分相移法和相移法之间的区别。

本文解释了精确的带内OSNR测量为何需要基于偏振解析光谱OSNR（PROS OSNR）技术的下一代OSA的原因。

本文将探讨一种OSNR测量方法，该方法不仅依靠承载数据的信号和噪声之间的偏振相对偏差特性，还利用它们各自的光谱特性。

本文概述了100G网络带来的各种测试挑战，以及EXFO应对这些挑战的解决方案。

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

This application note presents the FTB-5500B PMD Analyzer, based on the generalized interferometric method, allowing you to test whole links in one test sequence.

This application note explains how selecting the proper tool basically comes down to knowing your current and future needs as well respecting your budget.

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 pattern.

This article explains how service providers can make certain that all new 40G/100G circuits in service are proven capable of handling any of the demanding services thanks to EXFO’s FTB-85100G Ethernet-over-OTN testing capability.

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 reference poster provides an overview of advanced modulation schemes, plus it highlights the benefits of the PSO-200 Optical Modulation Analyzer. 

This reference poster provides an overview of section, line, high-order and low-order path overhead, as well as OTU, OPU and ODU. 

Technical essentials for deploying Ethernet networks and ensuring they are really ready for efficient data transmission.
