An industry colleague recently reached out to a few of us with a problem: A cable operator was having trouble with a cable modem termination system (CMTS) in his network. The manufacturer of that CMTS had claimed that it was “DOCSIS® Compliant,” and therefore this operator apparently had assumed it would just work. We checked […]

A brand new innovation, Full Duplex Coherent Optics uses the same wavelength, in two different directions, over the same fiber at the same time. As a result, Full Duplex Coherent Optics technology supports over 200 times more capacity compared to non-coherent digital transmission over a single fiber. This makes Coherent Optics technology well suited for deployment in […]

Ever-present communication is an important part of life these days. Cable technology provides connectivity for homes and businesses, providing entertainment, information and increasingly important functions for life. As we rely more on all forms of communications access, we rely on our cable modems to help keep services running their best. Cable modems have therefore become […]

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 […]

The CableLabs Proactive Network Maintenance (PNM) effort develops technologies and systems to proactively detect network problems before they impact the customer. In essence, our revolutionary technology turns every cable modem into a troubleshooting device, transferring that information to cable operators. Deploying PNM technologies results in faster and more accurate diagnoses of problems, faster repairs and […]

Last month, we announced the launch of the Remote MACPHY working group. As part of our Distributed CCAP Architecture program (DCA), the Remote MACPHY working group is comprised of operators, equipment manufacturers, and CableLabs’ engineers that help cable operators distribute their access networks. The charter is to develop one or more specifications that allow vendors’ […]

CableLabs Principal Architect Jason Rupe recently participated in Broadband Technology Report’s webinar “Proactive Network Maintenance (PNM) for DOCSIS 3.1.” Sponsored by SCTE/ ISBE, White Sands Engineering and VeEX, the webinar reviews PNM in the DOCSIS 3.1 context, the major benefits of PNM and how operators can best employ it. In particular, Jason discussed:  What is PNM? […]

The demand for data network capacity has been growing exponentially year after year with no sign of stopping. If the past is a guide to the future, the cable industry must come up with radically more efficient use of the existing cable infrastructure in order to meet demand. Today, the most constrained part of the network, and the […]

“I don’t want to have to share a pipe. The problem with ‘cable’ is shared pipes. If my neighbor is doing a bunch of stuff over the network, I get impacted too. With fiber I get speed and no shared pipes.” — Entrepreneur in a focus group The notion that subscribers connected to residential fiber […]
