Dense wavelength-division multiplexing (DWDM) is a widely used technology that allows to send a large number of optical signals, each having its own wavelength, onto a single optical fiber.

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.

The Internet of Things is upon us. And with it, a whole range of stacks and protocols to wirelessly drive the multitude of devices and applications. The wireless front has become a complex weave of multiple technologies.

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.

The complexity of testing processes, especially with regard to vendor-specific simulator and analyzer products, applications and automation, may mean that companies are not fully leveraging the capacity and capability of the equipment and services that they have invested in.

In the wake of continuous high-bandwidth growth that is placing increasing demands on the mobile network, many operators are modernizing their networks by making the switch from legacy copper to fiber-to-the-antenna (FTTA) infrastructures in an effort to better satisfy subscribers’ expectations.

100G is on a roll. True, it might no longer be a buzzword such as 400G, SDN, NFV, etc. But the fact remains that in 2014 we’ve seen major 100G deployments by Tier-1 operators and network equipment manufacturers alike. Significant rollouts are also expected next year, including the expansion of transatlantic networks to 100G, the upgrade of major US and European WDM backbones, as well as massive deployments in India and China. 100G is also starting to stir interest in South America and Africa, and a couple of projects are already underway.

Planning to deploy 40G/100G technologies? Well, there’s no escaping it; you have to choose between the green pill and the brown pill. In both cases, you win some and you lose some. It’s all about what you are ready to lose and what you want to gain. Choose well.

Impulse noise, which is a type of electromagnetic interference (EMI) typically emanating from power transmission, radio, TV, electronics, and cell phones, presents a host of challenges for today’s broadband service providers.

Early this November, EXFO launched, along with other Canadian telecom industry stakeholders, the Centre of Excellence in Next Generation Networks (CENGN) in Kanata, On. CENGN is a consortium of industry, academic and research leaders dedicated to accelerating the commercialization of next generation communications solutions.  CENGN will help bridge the gap between research and commercialization – a key component to building successful startup companies.
