Abstract
An optical signal amplifier includes a Raman fiber amplifier and a semiconductor optical amplifier. The Raman fiber amplifier utilizes pump radiation to amplify the optical signal resulting in an amplified optical signal. The semiconductor optical amplifier receives the amplified signal amplifying the amplified signal resulting in a twice amplified signal.
