OCN transforms broadband service with Harmonic

November 7, 2023

Harmonic has announced that Okinawa Cable Network (OCN) in Japan is using Harmonic’s cOS broadband platform (previously known as CableOS) to modernise its broadband network. With Harmonic, a specialist in virtualised broadband solutions, OCN now delivers reliable, high-speed internet service to its subscribers and has established a simple path to 10G fibre-to-the-home (FTTH).

“Harmonic’s cOS virtualised core software is well established with a proven track record for bringing agility to broadband operators, enabling more frequent, secure and efficient upgrades,” said Hiromitsu Awai, board director at Okinawa Cable Network. “Migrating to virtual CMTS and DAA with Remote PHY significantly reduces our operational expenses, with lower power, space and cooling costs. Harmonic’s cOS platform also empowers us to deliver faster bandwidth speeds over the DOCSIS network with high service availability, ensuring an exceptional broadband experience for our subscribers.”

OCN has deployed Harmonic’s cOS broadband platform in a distributed access architecture (DAA) with Harmonic’s Reef Remote PHY DAA shelves to address capacity issues with greater agility and cost efficiency. Harmonic’s cOS platform enables fiber and DOCSIS network convergence, simplifying future network evolution. The high-density Reef DAA shelves offer flexibility to handle bandwidth scaling at a low total cost of ownership. OCN is also using Harmonic’s cOS Central service-based cloud applications for proactive network intelligence, offering in-depth insight into system health and network performance. cOS Central integrates streaming telemetry data and AI capability to enhance broadband service quality in real time.

“OCN sought to respond to evolving connectivity requirements with strategic network transformation,” said Dan Gledhill, senior vice president, broadband business operations at Harmonic. “By replacing legacy iCCAP and network equipment with our cOS virtualized core software and network edge devices, OCN benefits from modern network capabilities, increased capacity, lower power consumption, improved network performance and are able to quickly deliver 10G fibre and DOCSIS broadband services over the same network infrastructure.”

Sumitomo Electric Industries, a Japanese-based reseller and system integrator, ensured a smooth deployment in a short period of time.

Harmonic’s cOS platform powers next-gen broadband services to more than 23 million cable modems for over 100 service providers worldwide, including leading operators in the US, Europe, Latin America and Asia.
