Infinera XTS-3300 Meshponder Delivers Industry-leading 19 Terabits of Capacity on Trans-Atlantic Route
Infinera, a provider of Intelligent Transport Networks, announced the successful completion of a subsea field trial with a major subsea network provider on a modern trans-Atlantic route.
The field trial was conducted with the Infinera XTS-3300 meshponder and demonstrated the potential of 19 terabits per second (19T) per fiber pair, delivering the highest spectral efficiency on a major trans-Atlantic route to operate with stable, commercial-ready performance margin.
Subsea optical networks are a critical piece of the global communications infrastructure, enabling cloud-based services to reach users around the world. Given the high complexity and cost of deploying submarine optical systems, subsea operators prefer high-performance, easy-to-use, high-capacity transmission equipment that maximizes their return on investment.
The XTS-3300 is powered by the new Infinera Infinite Capacity Engine 4 (ICE4) and is part of the Infinera Intelligent Transport Network portfolio optimized for long-haul subsea applications. It delivers the groundbreaking performance of Infinera’s ICE4 technology, including enhanced pre- and post-dispersion compensation, digitally synthesized Nyquist subcarriers and soft-decision forward error correction gain sharing.
The trial validates ICE4’s transmission of 8QAM (quadrature amplitude modulation) 600 gigabits per second (600G) super-channel in 140 gigahertz of spectrum, delivering the highest spectral efficiency of 4.3 bits per second per hertz with commercial-ready performance margin.
“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.”
