Harmonic Unveils SeaStar Optical Node for High-Speed Broadband

By Zacks Equity Research | May 29, 2025, 11:34 AM

Harmonic, Inc. HLIT recently announced the launch of SeaStar Optical Node, a state-of-the-art solution designed to deliver superior broadband connectivity in multi-dwelling units (MDUs). The legacy coaxial cabling systems used in many low-density MDUs lack the capability to facilitate multigigabit broadband connectivity required today. Upgrading the existing system and improving fiber connection is a costly and complex endeavor.

Harmonic’s optical node solution effectively addresses these issues. The solution converts the coax cables into high-speed broadband conduits. Leveraging the existing infrastructure, the solution facilitates an impressive speed exceeding 8 Gbps downstream and 1.5 Gbps upstream. It eliminates the need for costly rewiring and the risk of service disruption, and makes the process of network upgrades seamless for operators. 

Moreover, it allows operators to deliver high-speed broadband up to 5km away from a centralized point. To do that, it deploys several mini-nodes at the MDUs using point-to-point fiber connections. It also effectively mitigates issues occurred in RFoG (Radio Frequency over Glass) architectures, such as optical beat interference, limited bandwidth and higher latency.

The solution’s compact design and cost-effective nature make it a lucrative choice for improving connectivity infrastructure. Its high scalability and flexibility enable operators to swiftly adapt to evolving demand. One can easily expand capacity by adding a 10G PON port using Harmonic’s Fin OLT or an external OLT. The solution is powered by Harmonic's industry-leading cOS virtualized broadband platform, which provides a unified management of PON and DOCSIS services. This feature reduces capital expenditure, optimizes workflow and enhances operational efficiency.

Will This Product Launch Drive HLIT’s Share Performance?

Upgradation and deployment of high-speed broadband in low-density MDUs is a challenge due to costly infrastructure upgrades, service disruptions. Along with mitigating and addressing these issues, HLIT’s SeaStar Optical Node addresses key industry challenges in RFoG architecture. Owing to this, the solution is already gaining interest from leading communication solution providers like Netceed Poland. Its cost efficiency and high scalability are expected to drive faster market adoption and create a new revenue stream for broadband operators.

Harmonic is steadily advancing its portfolio to capitalize on the growing demand for high-speed broadband worldwide. The company is set to introduce Pearl R-OLT and Jetty-2 remote switch node modules that simplify the evolution process from GPON to XGS-PON, Combo PON, 25GS PON and beyond. Such innovative product launches augur well for long-term growth.
