Open Architecture Submarine Cable Observatory Systems

To deliver high power and broadband communication to the ocean floor requires a number of changes to existing technology developed to bridge oceans from shore to shore. The dry-dry solution is well mastered and although it evolves over time following technological innovations, adapting it to become a dry-wet solution represents a major technical challenge. The cabled observatory system developed for the Canadian part of the North-East Pacific Time-series Undersea Networked Experiment (NEPTUNE) encompasses major breakthroughs in several areas, including optical transmission, ocean engineering and powering.
