By Steve Condra – DOCSIS 4.0 technology, when implemented over soon-to-be-upgraded HFC networks, will cater to the demands of upcoming bandwidth-intensive applications. Yet, certain nuances continue to perplex the cable industry as it plans these upgrades.

By Ron Hranac – One of the most widely used metrics for characterizing the health of digital signals carried in cable networks is modulation error ratio (MER), or more specifically, receive modulation error ratio (RxMER).
Read MoreBy Keith Perry – One of the caveats of rolling out new technology in a service provider environment is that you must accommodate older technology, until such point where it’s no longer needed. Unfortunately, you may have no control over the time frame required to reach the expiration point

By Brady Volpe – DOCSIS 3.1 modems have ushered in a new era of high-speed connectivity. However, ensuring their consistent performance brings new challenges
Read MoreBy Steven Harris – With the increasing global deployment of the industry’s optical networks, it becomes imperative to uphold optimal levels for optical attenuation. This phenomenon refers to the diminishing intensity of an optical signal, commonly known as light

By The PHANTOM – Last quarter we talked about the bigger shoehorn of coherent fiber optics as one way to get more out of fiber we already have. You’ll recall (or maybe won’t recall) the simple definition my small brain uses, that we are treating fiber optics more like the way we treat RF-based signals. Rather than simple off-on modulation of the light (akin to the century old RF technique of code transmission), we can change the light carrier in ways that let us get more information through.

By Toby Peck, Greg Laughlin – As utility uncertainty continues to impact network resiliency, cable operators are looking for new solutions in energy storage to extend their network availability. Lithium-ion has the attention of the cable broadband industry for its advantages in high energy density and service life. To determine what is best for your network, there are several factors to consider.

By Nick Segura – As cable operators upgrade their HFC networks on the path to 10G, implementing a high-split 204 MHz architecture is a viable solution. This prevalent approach can deliver solid results with proper planning and foresight, particularly around modem transmit levels.

By Jeff Finkelstein – I have been writing articles, papers, and lectures for many years and one of the key things I have learned is one can never tell how many people read what you write.
