Raman amplification is a way of increasing the signal strength in an optical fiber. For submarine applications, Raman amplification minimizes the number of underwater repeaters, enhancing reliability and cost-efficiency, while in terrestrial setups, it facilitates ultra-long-haul links over thousands of kms with reduced infrastructure needs.
