Coherent Optics 101: Coming at You at 0.69c
November 23, 2020
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 […]
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 […]
Inform[ED] Video: Full Duplex Coherent Optics over Fiber Networks
March 15, 2018
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 […]
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 […]
