To gain better insights into the viewpoints of our network service provider customers, VIAVI partnered with Heavy Reading on their second iteration of the Open, Automated & Programmable Transport Networks Market Leadership Survey (along with Infinera and Fujitsu). The 2023 survey attracted a range of qualified network operator or communications service provider (CSP) responses from […]

One of the challenges with bi-directional (bi-dir) OTDR testing is the logistics and the amount of affordable, available, or required test equipment. A single-unit approach is usually considered to try and save on cost—one piece of test equipment versus two and one tech versus two—but it has its drawbacks. For one, it does not verify […]
Well, let’s start with why test at all? With all the time, effort, and money (particularly the money) put into the deployment of dark fiber or construction of fiber networks, owners and investors want to make sure they are getting good quality fiber links out of these projects. Everyone knows that some form of testing […]
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 Hz” approach – or […]

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. […]

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 […]
