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.

This video explores the various features and applications of the FTB-5500B PMD analyzer housed in the FTB-400 Platform

The FTB-5500B is the only PMD unit in the world to test through EDFAs, thanks to the mathematical subtraction of the autocorrelation peak in the interferogram.

This article simplifies polarization mode dispersion, using specific examples and formulas.

This application note describes how EXFO tested a transatlantic network for both PMD and CD with the PMD and CD analyzers set up in Europe, while the light source (FLS-5803) was based in Canada.

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 presents various PMD measurement approaches as well as a specific test case.

This application note explains the need for a test technology that would accurately measure CD and PMD in one instrument and from a single end, such as EXFO’s FTB-5700.

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 discussed.

This application note explains why it is important to test for chromatic dispersion and polarization mode dispersion, especially with the penetration of 40 Gbit/s, or OC-768/STM-256.

This paper demonstrates how measuring the total multiplath interference dispersion (MPID) is in many ways a significant advantage over pure PMD-measuring methods, particularly for testing components such as optical isolators.

This article provides an overview of polarization,a common factor in a number of phenomena that must be characterized if high-bandwidth systems are to attain their full potential.

This articles explains the importance of PMD in high-speed digital and analog networks; it has to be measured not only after manufacturing but also after cabling and installation.

This technical note provides an overview of EXFO's fully qualified and automated in-house power meter calibration system (EPMCS).

This article introduces the FPMD-5600, the ultimate PMD-testing instrument designed and manufactured so that its internal optical blocks could be inverted to respond to testing needs, as well as to adapt to devices with nominal PMD values.

This article explains why it is always more cautious to conduct dispersion testing for 10GigE applications—even on short-link networks.

This article demonstrates how the 40 Gbit/s technology will require more rigorous testing and emphasis on splice connections rather than connectors to prevent unnecessary power loss and to minimize the impact of MPI.

This article presents interaction mechanisms between aerial cables and wind; it gives an overview of the two embodiments of the SOP SSA method, and presents polarimetric measurement results and compares the polarization oscillation frequencies.

The exponential growth in Internet traffic and related drive for increased capacity introduce network complexities that necessitate advanced test solutions.
