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 […]

This year, our colleagues at SCTE•ISBE are taking full advantage of the power of connectivity to make one of the biggest industry events completely virtual—and FREE—to all attendees. The first-ever SCTE•ISBE Cable-Tec Expo® Virtual Experience (sponsored by Charter Communications, Comcast and Cox Communications) is scheduled for October 12–15, 2020, and we’re very excited to be […]

Today, we’re very excited to announce another successful milestone on the road to 10G. We’ve partnered with Mediacom Communications—one of the first cable operators to roll out gigabit service to all of its customers—and the NCTA-The Internet & Television Association to bring you a real-life demonstration of how 10G will power the smart home of […]
