Teleste announced that it took part in a live 1.8 GHz end-to-end network test, successfully completed at the '10G Showcase' demonstration organized by U.S. cable operator Charter Communications during this week's SCTE Cable-Tec Expo 2022 (Sept. 19-22) in Philadelphia.
In the demonstration, an end-to-end 1.8 GHz system was created with equipment from Teleste and other cable equipment vendors to showcase the performance of DOCSIS 4.0 technology. Following the DOCSIS 4.0 Extended Spectrum DOCSIS (ESD) amplifier cascade demonstration carried out with CableLabs earlier this year, the new demonstration further validates the cable industry's capabilities to achieve its symmetrical multi-gigabit services to the home. As noted by a Teleste statement, a path is now set out for operators looking to continuously increase data transmission speed and capacity in their hydrid fiber-coax (HFC) networks.
Charter's Cable-Tec Expo demo setup included five cascaded amplifiers and a booster from Teleste's 1.8 GHz ICON family. The implemented network test simulated the amplifier cascades becoming more typical with distributed access networks, confirming that the Teleste 1.8 GHz technology enables drop-in upgrades to existing amplifier locations.
A specialist in HFC technologies, Teleste leverages its RF engineering expertise to bring automation to intelligent amplifiers. The first 1.8 GHz amplifiers in the company's Intelligent Networks portfolio were introduced in 2021, including the intelligent ICON4300 amplifier, which was awarded by Broadband Technology Report in its 2022 Diamond Technology Reviews.

"An important promise for the cable MSO community is that the 1.8 GHz technology allows them to keep the existing amplifier locations without relocating them to shorten the coax sections in-between. We are pleased to have been able to demonstrate that, as a potential building block of the future 10G upgrades, this promise can be fulfilled. In addition to enabling multi-gigabit broadband speeds, the native intelligence of our 1.8 GHz amplifiers will potentially be a true game changer for operators, as their maintenance and management no longer requires highly-trained technicians, and their ability to self-balance will reduce periods of poor network performance and service issues when external environment impacts plant conditions." -- Hanno Narjus, head of Teleste's Networks business
