FOR IMMEDIATE RELEASE
SUNCALL Licenses SENKO’s SN® Connector Technology to Expand VSFF Connectivity Supply
[Hudson MA, USA– February 10, 2026] – SENKO Advanced Components, the pioneer of Very Small Form Factor (VSFF) connectivity, today announced that SUNCALL has entered into a licensing agreement to manufacture and supply products based on SENKO’s SN® connector technology. The agreement expands the availability of qualified SN® connectivity solutions for high-density optical networks.
This agreement expands the availability of SN® connectivity across the industry and reinforces SN’s position as a standardized VSFF interface for high-density optical networks. By enabling additional experienced manufacturers to supply SN® products, SENKO continues to support interoperability, resilience, and long-term scalability for data center and enterprise infrastructures.
Under the terms of the licensing agreement, SUNCALL is authorized to produce a broad portfolio of SN® products, including standard SN® connector and adapter solutions, as well as specialty products such as SN® Uniboot connectors and SN® shuttered adapters.
“As demand for VSFF connectivity continues to accelerate, it is paramount for the industry to have multiple sourcing options for critical connector technologies such as SN®,” said Phil Ward, Director of Strategic Marketing at SENKO Advanced Components. “By making SN® technology available to other established connector manufacturers, SENKO is strengthening the ecosystem, securing supply continuity, and providing customers with greater confidence as network density and performance requirements continue to grow.”
“This licensing agreement reflects a shared commitment to quality and long-term supply reliability,” said Kazu Toyama, COO of Suncall America Inc. “With decades of experience in precision optical connectivity, Suncall is well positioned to support SN® deployments through engineering expertise, consistent quality, and reliable supply.”
The SN® connector was designed to deliver up to three times the port density compared to traditional LC connectivity within the same panel footprint, making it a key enabler for space-constrained, high-fiber-count network environments.
This licensing agreement represents a positive signal for the optical connectivity market, demonstrating broad industry alignment around SN® as a scalable, open VSFF platform and ensuring robust supply as adoption continues to increase.
