In 1995, I attended a seminar in which the presenter told us that copper was dead, that we were approaching the limits of copper and that the future was fiber. However, fiber is not the answer to everything. The semiconductors that provide the processing power for the modern world are still electrical, not optical. Semiconductors create the data that must then be transmitted at rocket-ship speeds, and so the need exists for a copper connector that will allow extremely high-speed data to be taken from silicon to silicon, or silicon to fiber.
