Moving Towards 1.8 GHz Networks — What Does It Mean For Operators Today?

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.

PNM and Applications Make their way into Field Portable and Headend Test Equipment

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.

How Good Is Your Gigabit Service?

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.

DWDM is Coming to a Distributed Access Architecture Near You

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).

Addition of Complete OSP Offering Secures Amphenol Role as a Strategic Supplier

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.

Towards Greener Cable with Adaptive Powering

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.

PNM: More than Pre-Equalization Analysis

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.

PNM: More than Pre-Equalization Analysis

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.”

PNM Upstream Frequency Response? Of Course!

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.

PNM: Improving Workforce Efficiency and Subscriber QoE

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.
