What is BS EN 61290-10-5 - Optical amplifiers about?
BS EN 61290 is a series on optical amplifiers. 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 fibre through stimulated Raman scattering. The object of BS EN 61290-10-5 is to establish uniform requirements for accurate and reliable measurements, using an optical spectrum analyser (OSA), of the following DRA parameters:
