Unlike any year in recent memory, 2020 has scrambled our way of life, changing how we communicate, how we work and even where we go—on a global scale. At CableLabs, meetings were rescheduled, new rules were drawn up and enacted, and events were put on hold or went virtual. And still—despite the numerous logistical, psychological […]

If 2020 has taught us anything, it’s that connectivity is essential to our wellbeing and happiness. It fosters a sense of belonging—whether it’s to our family, our school, our company or just a random group of like-minded souls. And it’s not so much about the internet or the devices we use—it’s about experiences and staying […]

Welcome back, once again, to the CableLabs 101 series! In our most recent post, we discussed the fiber portion of the hybrid fiber-coax (HFC) network, as well as the coherent optics technology that’s widely considered to be the hyper-capacity future of internet connectivity. Today, we’ll focus on a topic of growing importance for many of […]

Welcome back to the CableLabs 101 series! In our previous post, we discussed the basic components of a typical hybrid fiber-coax (HFC) cable network infrastructure and the role of DOCSIS® technology in data transmission over the coaxial portion of the network. Today, we’ll focus on the fiber portion of the HFC network, as well as […]

In 1997, CableLabs released the very first version of Data Over Cable Service Interface Specification (DOCSIS ® technology) that enabled broadband internet service over Hybrid Fiber-Coaxial (HFC) networks.  Ever since, we’ve been making improvements, greatly enhancing network speed, capacity, latency, reliability and security with every new version. Today, cable operators use DOCSIS 3.1 technologies to […]

Welcome to the first installment of our CableLabs 101 series about a suite of breakthrough technologies that are instrumental in the path toward the cable industry’s 10G vision—a new era of connectivity that will revolutionize the way we live, work, learn and play. These technologies work together to further expand the capabilities of cable’s hybrid […]

The cable industry has been around since 1948, first delivering broadcast TV channels, then cable TV channels starting in the 1970s and finally—cable broadband internet in 1996. The introduction of fast-speed, “always-on” cable internet changed everything. It accelerated innovation across multiple industries and created whole new markets. Just take a moment to think: how many […]

Cable networks are fiber-rich, and cable operators have long invested in deploying more fiber deeper into their networks. A fiber-rich environment enables greater capacity, increased speeds and more flexibility to support a range of access technologies. Although cable broadband networks are typically composed of both fiber optic and coaxial cables, most cable customers are surprised […]
