  • Infinera and Seaborn Set Subsea Industry Benchmark for Capacity-Reach with XTS-3300 on Seabras-1

    Infinera and Seaborn Networks (Seaborn) announced the successful completion of a subsea field trial demonstrating the industry’s highest spectral efficiency on an ultra-long-haul subsea cable. The 8QAM trial demonstrated 4.5 bits per second per hertz on the Seabras-1 cable, owned and operated by Seaborn, with a distance of more than 10,500 kilometers (km), enabling up to 50 percent more capacity than systems without advanced coherent technologies such as Nyquist sub-carriers and SD-FEC gainsharing. This trial raises the bar for optical performance by delivering the industry’s highest spectral efficiency in a commercially shipping product.
