Imagine you’re a network engineer trying to manage the capacity of your DOCSIS networks — and suddenly you’re tasked with learning a whole new set of additional tools, techniques and terminologies to manage a new type of access network: a passive optical network (PON). Now apply that complexity to the entire operations, the many involved […]

The future of connectivity is being built today. As new solutions enter the market and industry leaders leverage emerging technologies and 10G breakthroughs, the cable industry is making a difference with powerful capabilities that reach into nearly every home. The best place to experience these advancements in one place is in person at SCTE® Cable-Tec […]

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 […]

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 […]

In our recent blog post, we talked about how, from a total cost of ownership (TCO) perspective, DOCSIS networks triumph as either backhaul or fronthaul over traditional fiber backhaul for the indoor use case. In this blog, we bring that TCO analysis to a more intuitive, outdoor use case: a head-to-head comparison between TCO of […]

In our recently published blog post, we demonstrated why indoor femtocells have reemerged as an attractive deployment model. In particular, indoor network densification has huge potential for converged cable/wireless operators who can leverage their existing Hybrid Fiber Coax (HFC) footprint to either backhaul from full-stack femtocells or fronthaul from virtual Radio Access Network (vRAN) remote […]

Last week, CableLabs Distinguished Technologist Steve Jia posted a blog “Doubling up on Fiber Capacity: A Winning Strategy for Full Duplex Coherent Optics.” In that blog, Steve describes how the CableLabs Full Duplex Coherent Optics innovation doubles the bi-directional capacity of each cable access network fiber, multiplies the capacity of each existing access network fiber […]

During our 2017 Winter Conference, CableLabs announced the launch of the point-to-point (P2P) Coherent Optics specification project, potentially multiplying the capacity of each existing cable access network fiber by over 100 times and possibly indefinitely deferring new fiber builds on existing routes. Now, a new CableLabs innovation, Full Duplex Coherent Optics: Doubles the bi-directional capacity […]

In a bit of alright, CableLabs recently welcomed Australia’s National Broadband Network (nbn) – as our 56th member — and our first in Australia.  CableLabs now has members across five continents — adding Australia to Asia, Europe, North America and South America. Established by the Australian government in 2009 to design, build and operate Australia’s […]

FTTH Connect was held earlier this summer in Nashville. Representing CableLabs and educating the audience about initiatives within the larger cable industry, Steve Burroughs, Curtis Knittle and I spoke at several sessions. In this short video, Steve, Curtis and I will share what we discussed and observed.     Video Transcript Curtis Knittle: I’m Curtis […]
