CableLabs Delivers Major Advancement in Fiber Access Network Speed

Point-to-Point Coherent Optics enable 10x increase in fiber capacity
Publish date:

LOUISVILLE, Colo.--CableLabs, the world’s leading innovation lab for the secure delivery of high speed data, video, voice and next generation services, today published its first Point-to-Point Coherent Optics specifications which dramatically increase capacity of the fiber access network by 10 times and will support 100 gigabits of data per wavelength. Coherent Optics technology uses amplitude, phase, and polarization to enable much higher fiber capacities which can improve streaming, video conferencing, file uploads and downloads and future usage needs for technologies such as virtual and augmented reality.

“CableLabs Point-to-Point Coherent Optics takes the existing fiber access network to hyper speed, boosting fiber capacity to meet the growing demand of broadband customers,” said Phil McKinney, president and chief executive officer of CableLabs. “Over half a billion people rely on CableLabs technology every day, and this breakthrough not only increases the capacity of the existing fiber system by an order of magnitude, it opens up wavelength resources to improve network quality and reliability, enabling advancements in cellular and wireless services.”

Gaining more capacity out of the existing fibers can eliminate the need to lay more fiber. The specifications allow multiple system operators to best leverage their existing fiber infrastructure to withstand the exponential growth in capacity demands and services for residential and business subscribers while enabling new services in the most cost-efficient way.

This announcement closely follows the launch of the CableLabs’ Full Duplex DOCSIS specification in 2017, reflecting the company’s ongoing commitment to the broadband consumer community, cable and fiber providers and other key industry stakeholders.

The Point to Point Coherent Optics specification effort was introduced by CableLabs last year and the completed specifications can be found on the CableLabs website.
