Leading Taiwan Broadband Operator Drives Fiber Deeper with Harmonic for Multi-Gigabit Broadband Connectivity

SAN JOSE, Calif., March 30, 2026 /PRNewswire/ -- Harmonic (NASDAQ: HLIT) today announced that KBRO, a leading multiple-system operator in Taiwan, is evolving its next-generation broadband access network with Harmonic's fiber-on-demand solution powered by the industry-leading cOS™ virtualized broadband platform. The Harmonic PON solution compliments KBRO's DOCSIS high-split network modernization strategy by enabling demand-driven fiber expansion for multi-gigabit broadband service delivery across the operator's footprint. Building on KBRO's successful implementation of Harmonic's cOS platform to converge its fiber and DOCSIS networks, this expansion supports KBRO's vision for a flexible architecture for long-term service evolution.

"We see the future of the broadband market in Taiwan to be defined by fiber-deep innovation and scalable infrastructure," said PK Lee, Vice President of Engineer at KBRO. "Our focus is on providing outstanding broadband experiences to our customers while managing our investments responsibly. Expanding our partnership with Harmonic enables us to deploy fiber where demand is strongest and efficiently deliver next-generation broadband speeds across our network."

Harmonic's fiber-on-demand solution allows KBRO to surgically and quickly activate advanced fiber services directly from existing Harmonic Oyster Remote-PHY nodes. This approach eliminates redundant infrastructure and aligns network expansion directly with revenue opportunities. This strategy also helps KBRO cost-effectively and sustainably upgrade to XGS-PON technology, enabling better-priced multi-gigabit speeds and greatly expanding the operator's network capacity.

"KBRO continues to demonstrate strong leadership in advancing broadband infrastructure in a competitive market," said Jeffrey Glahn, Senior Vice President, Global Sales at Harmonic. "At Harmonic, our goal is to provide broadband service providers with a practical path to expand fiber strategically and efficiently. KBRO implementation of Harmonic's fiber-on-demand architecture in the APAC market reinforces our expanding presence in global fiber modernization initiatives. We are proud to support KBRO's continued network evolution and long-term growth."
