Fibre optic active components and devices. Performance standards - Seeded reflective semiconductor optical amplifier devicesWhat is BS EN 62149 8 Fibre optic active components and devices about? BS EN 62149 is a series on fibre optic active components and devices. Fibre optic active components and devices are electronic components made up of semiconductor materials that actively manipulate electrons to perform the intended function. BS EN 62149 8 covers the performance specification for seeded reflective semiconductor optical amplifier (RSOA) devices used for fibre optic
