Infinera completed a trans-Atlantic field trial with it’s new XTS-3300, slightly edging out the performance of previous announcements by Ciena and Nokia for trans-Atlantic links.

While optical vendors have demonstrated experimental approaches to boost subsea fiber capacity, the Infinera XTS-3300 is the first commercial platform that can deliver over 19T of capacity on a trans-Atlantic route,” said Andrew Schmitt, Lead Analyst at Cignal AI. “The XTS-3300 trial used tighter channel spacing and advanced compensation techniques in the DSP, paving the way for operators to deploy highly efficient platforms that maximize subsea fiber spectrum utilization.
