An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. BS EN 61290 10 5 applies to distributed Raman amplifiers (DRAs). DRAs are based on the process whereby Raman pump power is introduced into the transmission fibre, leading to signal amplification within the transmission
