CableLabs this week took the wraps off its next development in optical technology, building on the non-profit cable R&D organization's prior work applying coherent optics to last-mile broadband infrastructure.
In a detailed article on Light Reading, Senior Editor Mari Silbey discusses CableLabs' most recent work, which is designed to improve operators' efficiency when they deploy coherent optics in the access network. With the organization's advances, coherent optics -- which are most often found in long-haul networks -- may well make this technology viable for deployment closer to the subscriber's home, she writes.
Dubbed Full Duplex Coherent Optics, the project incorporates bidirectional traffic over one medium, optimizing network infrastructure by empowering traffic to simultaneously flow in both directions over an optical fiber link.
Today, about one-fifth of residential cable deployments use one fiber that taps multiple wavelengths for upstream and downstream traffic, according to Steve Jia, distinguished technologist for wired technologies at CableLabs. But that could grow to 60% in the near future, says Jia, as cable operators use additional fibers for offerings such as commercial services.

As MSOs add networking equipment to support the growing number of node counts, rack space and power-cooling capacities at hub sites, DAA technologies such as Remote PHY become even more attractive, writes Viavi's Jim Walsh.
During prepared comments to a conservative group in Maine, Federal Communications Commission Chairman Ajit Pai outlined his concerns with several states' independent moves to reinstate the 2015 laws governing the Internet.
Fast, reliable broadband is essential to how we live, work and play today – and the upcoming arrival of 5G will only further increase demand and reliance on fiber infrastructure. Already viewed by consumers as intolerable, delays, outages or the regular maintenance difficulties associated with operating a network will become further exacerbated when residential subscribers further rely on connected devices for day-to-day life. Just as providers deploy network automation tools to reduce operational issues, they must take similar care to manage consumer expectations when they roll out fiber or new services. This webinar features leaders who will discuss how to manage marketing and consumer expectations at every stage of the network lifecycle. Marketing professionals, c-level executives and policymakers interested in drumming up fiber envy should attend.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
