Hear firsthand from open-access provider F6 Networks about the impact the EXFO Fiber Guardian unit had on reducing fiber fault location from hours to minutes, in turn keeping customers informed and reducing OPEX with less truck rolls when they suffered a fiber cut in a remote location after the Maritimes were hit by tropical storm Arthur in July 2014.

When it comes to deploying high-speed 40 Gbit/s or 100 Gbit/s technologies, today’s operators must choose which type of architecture will support the new wavelengths. Will they opt for a “brownfield” deployment, which uses an existing network, or a “greenfield” deployment, which employs new or unused fibers?

With technology changing at a rapid pace, mobile operators are faced with the unique challenge of administering the appropriate level of cellular capacity and coverage to customers at the lowest possible cost, and with best-in-class services. The need to stay connected 24/7 to millions of innovative applications in any building or at any event is placing enormous pressure on carriers to adapt their access strategy in order to alleviate blind spots and congestion issues.

For almost two decades, you have been embracing the benefits of EXFO’s single-ended testing methodology for copper testing in comparison to solutions that were “dual-ended”, particularly with measurements such as attenuation (loss) and longitudinal balance. EXFO’s methodology for single-ended testing simply required an open circuit at the far end so that we could perform the necessary analysis during the measurement to provide you with the right result.

If you didn’t know already, resistive-fault-location (RFL) testing consists of a powerful measurement that is capable of locating high-resistive faults on copper pairs. Although there are other methods for determining fault location, notably time-domain reflectometry (TDR), this particular measurement typically requires an extremely low-resistance fault (e.g., <100 Ω) in order to be reliable.
