All-optic networks provide network capacity within the Photonic Domain. The Photonic Domain involves the use of radiant energy with photon as its fundamental element. Likewise, as electronic applications use electrons, the Photonic uses the photon. The intelligent all-optic networks are redefining the optical industry, in fact, it is re-shaping the future. An all-optic network […]
The future of the network: 5G, Fiber Optics & Edge Computing A digital network is, in layman’s terms, a transportation system for information. Imagine the system to be a factory floor conveyor belt. In this scenario, edge computing processes are ‘stations’ placed as far out as possible on the belt to make it faster […]
Tag – You’re It! Signal Tags and Their Use in Cable Signal Leakage Detection Cable signal leakage technologies have been around for more than three decades, and while the underlying concept of detecting CATV signals leaking out of the network has not changed, the technologies to accomplish this have changed considerably. Shortly after the first […]
Change Ahead – How Network Maintenance Practices Are Evolving With The Rapidly-Changing HFC The recent pace of change in HFC networks has been dizzying compared to our previous gradual evolutionary path, but fortunately plant maintenance practices including plant leakage detection have evolved to stay ahead of the curve. The rapid expansion of FTTH offerings combined […]
Tune In – Antennas are the Eyes and Ears of Signal Leakage Systems Despite huge improvements in computing power available to design tools and simulations, RF antenna design remains at least somewhat of a black art. The best antenna designers are often brilliant Engineers, but most will admit that past experience and quite frankly luck […]
Why Signal Leakage, Why Now? Ingress has been the single largest thorn in the side of cable operators since the advent of CATV plants, only to be aggravated by the introduction of two-way services. Despite decades of innovation, the silver bullet solution to fully address this problem remains elusive. Why Ingress Is Such a Challenge: […]
The HFC Evolves Through the years, with the demand for additional speed and bandwidth cable systems have: Migrated from analog channels to 6 MHz SC QAM channels Migrated from modulation schemes from 16 QAM up to 256 QAM channels Migrated to DOCSIS 3.1 OFDM carriers consuming much larger areas of the spectrum Began migrating from […]
The Early Days of CLI Leakage The new regulations required the operator to monitor, measure with a specific technique, and log all system leakage. The operators soon realized that this was a difficult task with their current equipment, as signal level meters had insufficient sensitivity to measure 20 uV/m at even 10ft, much less be […]
Signal Leakage in Cable Networks, a Long and Winding Road Cable is a unique communications medium that has evolved from a rudimentary patchwork of transmission lines and components devised by an industrious group of technology pioneers decades ago into the leading broadband juggernaut that it is today. The remnants of this journey are still evident […]
Fiber Deployment is on the rise (no shock there). How do you transfer need-it-now, real experience to a new (and inexperienced) fiber tech? There are any number of things that you can point to to demonstrate what is driving growth in fiber deployment including regional FTTH/PON initiatives, national high-speed broadband growth, core 100/200G upgrades, or […]
