As high-bandwidth requirements continue to rise over the last few years, multiple system operators (MSOs) transform their hybrid fiber/coax (HFC) networks. Available architectures, such as DOCSIS 3.1 and Remote PHY, rely on fiber-based bandwidth deep into the cable television (CATV) network, which is why countless operators aim to create Node+0 architectures via “fiber deep” initiatives. […]
Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years. In this entry we will discuss the “more Nodes” approach – how […]
Reliance on global high-speed telecommunications is higher than ever before. From urgent financial transactions to endless video live-streaming, undersea cables support numerous aspects of our modern lifestyle that we may not be aware of, making it one of the backbones of the global economy. In fact, commercial undersea cables carry about 97% of the world’s […]
DWDM is moving into access networks at a higher rate than ever before. This includes cable service providers upgrading to the newer distributed access architecture (DAA), both cable and traditional telecom service providers to deliver business services, and wireless service providers as part of their centralized RAN (C-RAN) approach as well as a key part […]
As we know, the demand for broadband services is on the rise and demand is not restricted to towns and cities. Folks living in rural locations need good-quality, high-speed services just as much as their urban cousins. For the majority of cases, especially greenfield sites with no existing infrastructure, Passive Optical Networks (PON) and Fiber-to-the-Home […]
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 […]
The Passive Optical Network (PON) is a telecommunication technology that is used to implement a point-to-multipoint architecture. In order to enable a single optical fiber, the system uses fiber optic combiners and splitters, which is then used to serve multiple end-users without the need for individual fibers between customers and the hub. The coverage range […]
