In today’s increasingly competitive market, worldwide carriers and network operators are striving to deliver the bandwidth required for residential, mobile and enterprise services, and consequently upgrading to 40G/100G. Discover our 40G/100G product portfolio, and get the tools you need to accelerate time to market, save costs, and deliver high-speed services.

An examination of the value of analytics and reporting tools to provide comprehensive information across the organization, such as differentiating between services based on more than just speed or price and comparing the service quality and usage across peak days and hours.

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

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 application note explains the need for specialized dispersion tools to provide high accuracy and perform EDFA testing and distributed PMD measurements for bad section localization.

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.

This article reports and analyzes states of polarization (SOP) and polarization mode dispersion (PMD) measurements on aerial fiber under moderate to severe wind conditions.

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

The lowdown on Fibre Channel storage area networking (SAN) technology and recommended testing methods. 

An overview of four 40G market drivers, two major components in any 40G network—ROADMs and OTN—and EXFO’s solutions for 40G fiber characterization, link commissioning and upgrade as well as wavelength services turn-up.

A summary of the main challenges of 40 gigabits transmission networks, such as polarization mode dispersion, chromatic dispersion and optical signal-to-noise ratio measurements, particularly in a mesh network. Solutions to overcome those challenges are also presented.

An overview of the evolution in bandwidth and the promising 100G technologies that are leading the way, as well as an examination of the new paradigm of testing challenges created—both in the lab and the field.
