What’s in a Name? The Value of CableLabs Certification/Qualification for Cable Operators

May 31, 2018

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 […]

What is Full Duplex Coherent Optics?

May 24, 2018

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 […]

Doubling up on Fiber Capacity: A Winning Strategy for Full Duplex Coherent Optics

March 8, 2018

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 […]

Pinpointing Signal Leakage and Noise Ingress Demo

February 15, 2018

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 […]
