Leakage Uses Changing The first half of 2020 has certainly seen significant changes in the world around us, including how customers receive and use the services carried over our networks. Bandwidth consumption (especially the upstream) have skyrocketed with the pivots to eLearning and working from home, as has the criticality of the services that we […]
Fiber is being pushed deeper and deeper into access networks worldwide as service providers continue to address subscriber demands for higher capacity services. Going “fiber deep” could be part of G.fast deployments for telco operators or Distributed Access Architecture (DAA) upgrades for cable companies, but the next step (or end step) is full fiber-to-the-premise (FTTP) […]
There are any number of things you can point to that demonstrate what is driving growth in fiber deployment, regional FTTH/PON initiatives, national high-speed broadband growth, core network 100/400G upgrades, or preparation for new services such as 5G. One thing that is critical for these new or upgraded services to function to their peak and […]
Make The Connection – How Your HFC Tools Can Work Harder For You The people who monitor and maintain HFC networks have an impressive if not overwhelming number of tools available to them today. Some of these tools like upstream spectrum analyzers and plant leakage systems have been around since the early days of […]
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 […]
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 […]
