Harmonic has released an upgrade kit that enables Cisco GS7000 nodes to support the distributed access architecture and DOCSIS 4.0 as the widely-deployed Cisco equipment nears its end-of-life.

Meanwhile, the supplier is seeing 'high-split' trials and deployments perk up as cable operators seek ways to expand upstream capacity on DOCSIS 3.1 networks.

Fresh off a big 5G core deal with Verizon, the cable and wireless supplier is forced to suspend 2022 guidance as visibility is being obstructed by persistent component shortages and general supply chain issues.

Charter, a champion of the 'Generic Access Platform' initiative, showed off a standards-based node capable of supporting DOCSIS, PON and even wireless service modules. Deployments could get underway in 2023.

Harmonic's cable access revenues almost doubled in Q1 as CableOS deployments grew to 6.1 million, with 77 operators signed up to their virtualized access network platform.

Revenues for remote OLTs surged to $10 million in 2021, compared to just $300,000 in 2020, and are poised to more than double in 2022, according to Dell'Oro Group.

Elad Nafshi, Comcast's chief network officer, details how the operator will roll out DOCSIS 4.0 over a virtualized platform that will also support targeted deployments of FTTP.

Industry experts believe DOCSIS 3.1 can keep pace with today's fiber competition by pairing a 1.2GHz upgrade with an upstream-expanding 'high-split.' But emergence of new PON technologies could limit the role of DOCSIS 4.0.

As we have for the past two years, Light Reading will stage the Cable Next-Gen Technologies & Strategies conference as a free digital event over two half-days next Tuesday and Wednesday.

CEO Jerry Guo said supply chain issues are holding the company back. He billed 2022 as a 'transition year' as Casa focuses on cloud software and scales back lower-margin hardware products.

Cloonan, who most recently served as interim CTO at CommScope, is a cable industry engineering exec who has played a key role in the evolution of DOCSIS – from 1.0 to 4.0.

Company is also reorganizing its remaining 'core' business into four divisions, including a new Access Network Solutions unit led by cable industry vet Guy Sucharczuk.

Alaskan operator is also deploying a distributed access architecture as GCI presses ahead with a plan to bring 2-Gig speeds to 77% of the state in 2022.

Revenues related to the distributed access architecture, a prerequisite for DOCSIS 4.0, stayed solid, but growth was constricted by ongoing supply chain issues.

Proof-of-concept test with Bluepeak tapped the AWS cloud in Ohio to control a Vecima remote MACPHY node located about 1,000 miles away in South Dakota.

As we have for the past two years, Light Reading will stage the Cable Next-Gen Technologies & Strategies conference as a free digital event over two half-days in mid-March.

Supplier says deployments of its 'CableOS' virtualization platform have reached 73 service providers worldwide and now serve 4.8 million modems.

Revenues in the cable concentrator market dipped year-over-year in Q3 2021, but accelerated on a sequential basis as operators bulked up on network hardware and deployed capacity-enhancing node splits.

Canadian cable op will tap Harmonic's virtual CCAP and DAA gear as part of a plan to support multi-gigabit services, shift to an all-IP services platform, and cut a 'clear path to DOCSIS 4.0.'

DOCSIS and advanced HFC technologies will remain key areas for CommScope, but the vendor is set to launch a new XGS-PON platform in the coming months amid a broader, companywide transformation initiative.
