The field of submarine system design is always in search of new cost-effective, power-efficient, and highly reliable approaches to increasing overall cable capacity. Significant recent advances have been made in this area by the addition of transmission bands and fiber pairs per cable, and by new design paradigms for power-efficient optimization of total cable capacity.
Multi-core fiber technology could be the next likely step in undersea cable design to support the rapid increases in internet capacity, with up to 500 Tbit/s per fiber demonstrated over trans-Pacific distances in the laboratory. Multi-core fiber solutions also provide higher physical density, a key characteristic for space-limited submarine equipment. The power-efficient and cost-effective amplification approaches required for multi-core fiber transmission systems are an ongoing area of research.
The focus of this panel will be the challenges and solutions for implementing massive spatial and spectral multiplexing SDM technology within the unusual design constraints of undersea cable systems. Speakers from fiber and optical component suppliers, submarine system providers, and network owners will present their views on the evolution of high-capacity submarine transmission systems, and whether multi-core transmission technologies will play a role in that future.
