SENKO’s SN® Connector Enables High-Density 4×400G Breakout in Accelink’s 1.6T O-band Coherent Lite OSFP-XD Module at OFC 2025

[Hudson MA, April 1st, 2025] – SENKO Advanced Components, a global leader in optical interconnect solutions, is proud to announce that its cutting-edge SN® connector has been integrated into Accelink’s 1.6T O-band Coherent Lite OSFP-XD optical module. This breakthrough solution, developed by Accelink, is designed to achieve a reach of up to 20km, setting a new industry benchmark for high-speed, long-distance optical transmission.

Accelink will showcase a live demo of the 1.6T O-band Coherent Lite OSFP-XD optical module at OFC 2025, held at the Moscone Center in San Francisco from April 1-3, 2025. Attendees can visit Accelink at booth #1531 to see the module’s capabilities firsthand.

Accelink’s 1.6T O-band Coherent Lite OSFP-XD optical module

The 1.6T O-band Coherent Lite OSFP-XD optical module features a high-density architecture, delivering 4×400Gbps transmission with advanced 3D-stacked optoelectronic co-packaging. Operating at 1311nm, the module supports distances up to 20km, enhancing receiver sensitivity to -20dBm while minimizing dispersion. Additionally, its use of fixed DFB lasers as a cost-effective local oscillator eliminates the need for complex control circuits, reducing both system complexity and cost.

SENKO’s SN Connector:

The Industry’s Leading VSFF Solution The SN® connector, developed by SENKO, is a Very Small Form Factor (VSFF) interface that enables four duplex connections within the OSFP-XD footprint. This compact and efficient design enhances port density, simplifies the 4×400G breakout process, and provides a seamless, high-performance interconnect for next-generation transceiver applications.

“We are proud that our valued partner, Accelink, has chosen to integrate our SN® connector into their latest 1.6T transceivers,” said Phil Ward, Director of Strategic Marketing at SENKO Advanced Components. “The SN® connector was developed specifically for ‘direct breakout’ capability, and the ability to directly breakout 4 × 400G duplex ports from a single transceiver is truly spectacular.”

“The integration of SENKO’s SN connector into our 1.6T O-band Coherent Lite OSFP-XD optical module enhances user experience with a high-density, plug-and-play solution,” said Tiger Ninomiya, Principal Technologist at Accelink. “This advancement allows us to deliver an efficient, long-reach solution tailored for next-generation optical networks.”

Revolutionizing Long-Distance Optical Communication With its industry-leading performance and space-efficient design, the 1.6T O-band Coherent Lite OSFP-XD optical module is poised to transform high-speed optical connectivity. By incorporating SENKO’s SN® connector, Accelink is delivering a scalable, cost-effective, and deployment-ready solution for data center and telecom applications.
