Ribbon Communications Revolutionizes Trans-Pacific Connectivity with Groundbreaking Optical Transmission Trial

Ribbon Communications Inc. (Nasdaq: RBBN) achieves a significant milestone in the realm of high-speed connectivity with the completion of a pioneering optical transmission field trial on the JUNO trans-Pacific submarine cable. This cable, developed by Seren Juno, is poised to become the largest trans-Pacific link between Japan and the United States, boasting an impressive total capacity of over 350Tbps across 20 fiber pairs. As global demand for swift and reliable internet access escalates, this trial establishes Ribbon's Apollo platform technology as a leading solution, capable of transmitting an astonishing 20Tbps per fiber pair over extensive distances.

The trial utilizes Ribbon's state-of-the-art Apollo 9408 transponder, which incorporates advanced 5nm 140GBaud technology. This enables flexible modulation from 400Gbps to 1.2Tbps per wavelength, optimizing performance based on varying cable conditions. Sam Bucci, Ribbon's Executive Vice President and Chief Operating Officer, underscores that the successful outcome of this field trial exemplifies the scalability and robustness of their technology. He emphasizes that the ability to achieve such high transmission rates over long distances is crucial for meeting the increasing demands of global communications infrastructure.

Yoshio Sato, CEO of Seren Juno, expresses confidence in the results of the trial, noting that they rival the performance of leading competitors in the industry. This development opens up new strategic opportunities for both companies in the evolving landscape of telecommunications. Ribbon Communications not only focuses on advancing technology but also remains committed to delivering secure cloud communications and networking solutions while prioritizing environmental, social, and governance (ESG) criteria. Their annual Sustainability Report reflects this commitment, marking Ribbon as a forward-thinking player in the optical networking sector.

In addition to this groundbreaking trial, Ribbon Communications continues to innovate in the field of real-time communications technology. Their advancements position the company as a key contributor to the future of global connectivity, reinforcing the importance of high-capacity networks in an increasingly digital world.

Ribbon's commitment to environmental sustainability and responsible governance further distinguishes the company in a competitive market, appealing to stakeholders looking for socially responsible investments in technology. As the demand for high-speed internet continues to grow, Ribbon’s achievements in optical networking could redefine the landscape of global communications infrastructure.
