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.

Using fixed wireless, a merged Sprint/T-Mobile could reach about 85% of those the FCC defines as unserved and underserved rural customers, Sprint Chief Technology Officer John Saw told attendees at the Wells Fargo 5G Forum in New York on Thursday.
ADTRAN is now an Open Networking Foundation supply chain partner and strategic advisory board member, placing the vendor at the forefront of ONF's development of a new reference design process for future networks.
MobiTV will launch MobiTV Connect in July, a multi-tenant managed streaming service that already boasts delivery rights from more than 210 major networks and 35 service provider customers, says MobiTV CEO Charlie Nooney.
Australian wholesaler nbn eliminates costly and disruptive trenching of homeowners' driveways by using copper to deliver last-mile connectivity from sidewalk-based Distribution Point Units (DPUs) to subscribers.
We will explore several fiber network environments, common vulnerabilities, and the business impact of failures. Fiber networks are typically a combination of owned and leased fiber. Learn how to reduce MTTR by up to 60% when an event occurs and how to detect degradation before it generates a service impact. Fiber monitoring of leased fiber helps ensure that the responsible party is dispatched for repair and SLAs can be managed. We will discuss both in service and out of service monitoring. Learn about the opportunities to improve business results in the following environments:
Hyperscale datacenters- the business need for near 100% uptime
5G small cell combined with leased fiber - ensuring the SLA for leased fiber
Long haul and Metro dark and lit fiber monitoring - reducing MTTR and preventing damage
FTTX construction and service activation in the access or MSO network - accelerating time to revenue
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.
