Pasi Järvenpää – The insatiable demand for bandwidth, the growing need for reliability, competitive dynamics, and the need to expand their footprint are driving operators to massively invest in their network infrastructures and operations.

By Juan Bravo – There’s a little irony in the fact that now it seems more than ever, cable operators are seriously seeking ways to make the most of their extensive legacy HFC infrastructure

By Jim Kane – The distribution network may be limited, however, by the capacity available in its outside plant (OSP) splice closures, particularly those that are near or have already exhausted internal space.

By Steve Condra – As the study concluded, even four amplifiers in a cascade can carry the magical 10 Gbps capacity. However, it is clear that to harvest the full potential of HFC networks, 1.8 GHz amplifiers should perform automatic adjustments. Alternatively, cable technicians should define rigorous methods to confirm that amplifier cascades are tuned to perfection even when outdoor conditions, such as temperature, change.

By Erick Davila – VeEX’s RTU-320 operates as both a TCP server and TCP client when testing against field test equipment. The RTU-320 performs bi-directional upstream and downstream tests, IPv6 V-PERF, bi-directional V-PERF that combines client-to-server and server-to-client tests into one. With up to two independent test blades, the RTU-320 enables 4x 10 Gbps test interfaces ensuring reliable and repeatable data.

By Bernie Cadieux – As DOCSIS continues to spread its wings, new applications are emerging, too. As previously mentioned in last year’s advertorial, non-intrusive measurements leveraging adaptive equalization coefficients are being introduced more and more as non-intrusive alternatives to more traditional (and sometimes intrusive) methods.

By James Medlock – It seems like every day there is another press release announcing a new or expanded DOCSIS® 3.1 based gigabit service. Many operators have reported heavy interest from their subscriber base, looking for higher speed services to support the increasing number of devices and applications that they rely on each day.

By Greg Calton – In the fast-paced environment of broadband communications, a simple approach to the creation and growth of networks is highly desirable. Strategic suppliers can help broadband service providers by bringing entire solutions to the table from a variety of technical disciplines.

By Rami Kimari – Energy consumption in broadband networks is significant and so is their environmental impact. According to some studies, the carbon footprint of the Internet already exceeds that of global air travel [1], posing a challenge to the traditionally energy-dependent cable industry.

By Mike Venter – The cable industry’s optical networks are undergoing rapid and radical changes to support new distributed access architectures (DAAs). A DAA basically involves replacing legacy analog infrastructure with new remote PHY devices (RPDs) or remote MAC/PHY devices (RMDs).

By James Medlock – When you ask cable operators who have not deployed a proactive network maintenance (PNM) solution why, the first response is usually something along the lines of, “we have too many problems to fix already, we don’t have time for any more.”

By Cyrille Morelle and Winston Chang – When it comes to modern monitoring systems, proactive network maintenance (PNM) and predictive modeling are major parts of the solution to increasing customers’ quality of service and expectations. Advanced cable modems can now provide the information needed for constant monitoring at the customer premises.

By Bernie Cadieux – With the advent of the latest DOCSIS versions, new technologies emerge and new ideas are founded on the newly available data: full band capture, pre-equalization coefficients, non intrusive measurements, and more.

By Brady S. Volpe – No longer are “Alarms” the first line of defense Proactive network maintenance (PNM) is used by the world’s largest cable operator and by operators of all sizes globally with great results. It has become the essential tool in the industry for many operators.

By Matthew Shapson – MoCA has changed the way customer premises installations are completed. Today’s technicians are dealing with an additional layer of home networking in a frequency range that is being encroached upon by the expanding cable network spectrum.

By Luc Absillis and Sudheer Dharanikota – The ever-increasing customer appetite for higher bandwidth services is magnified with impending introduction of new technologies, such as: 5G, high speed fixed wireless access, and 10 Gbps fiber to the home.

By Jonathan Haight – Over the last two years, we’ve seen a blurring of the lines between mobile network operators (MNOs) and multiple system operators (MSOs) and mobile virtual network operator (MVNO) Agreements are being executed throughout the mobile industry.

By Wolter Rebergen – Evolving Your Network – Remote PHY (R-PHY) technology enables the up- and downstream relocation of traditional headend elements, delivering 10 Gbps to a remote location.

By Cyrille Morelle and Brady Volpe – The subscriber’s increasing expectations of quality of experience (QoE) and network speed has pushed the development of more demanding protocols. The industry is now rolling out DOCSIS 3.1 OFDMA to the field and many providers are planning their transitions to the upcoming full duplex bidirectional communication (FDX) standard.
