Harmonic Revolutionizes MDU Broadband Connectivity with New SeaStar Node

San Jose, California – On May 28, 2025, Harmonic Inc. (NASDAQ: HLIT) announced a significant breakthrough in broadband connectivity with the launch of its new SeaStar™ Optical Node. This innovative technology is specifically designed to improve broadband service delivery in lower-density multi-dwelling units (MDUs), making it a game-changer in the industry.

Summary of the SeaStar Node

The SeaStar node addresses a critical challenge faced by broadband operators aiming to provide effective, high-speed connectivity within existing infrastructures. By converting current in-building coaxial cabling into a robust high-speed conduit, the SeaStar node allows for the efficient deployment of fiber-grade services without the need for extensive infrastructure changes. According to Nimrod Ben-Natan, Harmonic's president and CEO, “The SeaStar node tackles a longstanding broadband industry challenge — delivering multigigabit connectivity to MDUs without costly infrastructure changes, complex permits, and service delays.”

Features and Benefits

The SeaStar node not only simplifies the connection to multigigabit broadband but also significantly reduces operational costs. Here are some key features of the SeaStar node:

• - High Speed and Efficiency: Capable of delivering upstream speeds of 1.5 Gbps and downstream speeds that exceed 8 Gbps, the SeaStar node ensures that residents in MDUs have access to premium broadband services.
• - Cost-Effective Deployment: By eliminating the necessity for expensive rewiring and minimizing service disruptions during upgrades, the SeaStar node empowers operators to achieve rapid deployment and efficient service upgrades.
• - Scalable Technology: Harmonic's unique design allows the deployment of up to 16 mini nodes from a single SeaStar node, providing flexibility for operators and ensuring extensive coverage within MDUs.

Technical Innovation

One of the significant aspects of the SeaStar node is its ability to address common issues found in traditional fiber deployments. Thanks to its advanced design, the SeaStar node overcomes challenges like optical beat interference (OBI) and limited bandwidth scenarios that typically plague residential broadband settings. With its capability to service MDUs located up to 5 kilometers from the central point, the SeaStar node stands out as a scalable, future-proof solution.

Moreover, the node is built to accommodate next-generation fiber technologies, making it adaptable to changing market demands. Operators can introduce 10G PON ports easily as subscriber needs expand, ensuring that service providers can keep pace with the growing demand for bandwidth.

Streamlined Operations

Harmonic's cOS™ virtualized platform is at the core of the SeaStar node, facilitating the management of both PON and DOCSIS services through a unified interface. This integration enables operators to streamline their operations effectively, minimizing operational expenditures (OPEX) while improving workflow efficiency.

Industry Responsiveness

Netceed Poland, a prominent distributor in the broadband landscape, has expressed support for the SeaStar node, highlighting its significance in the market. Arek Zawada, managing director at Netceed Poland, stated, “Harmonic's new SeaStar node is exactly the kind of solution the broadband industry has been asking for — flexible, cost-effective and purposely designed to address the critical need for fiber-grade connectivity in MDU deployments.”

Future Demonstrations

Harmonic is set to exhibit the SeaStar node at two major upcoming events: Fiber Connect 2025 in Nashville (June 1-4) and ANGA COM in Cologne, Germany (June 3-5). Visitors can expect to see firsthand how the SeaStar node redefines expectations for broadband connectivity in multi-dwelling units.

For those looking for a cutting-edge solution in broadband connectivity, the SeaStar node promises to be a transformative option for operators seeking to enhance service offerings while minimizing costs and maximizing efficiency.
