System and method for per-band optical amplification

摘要

A method and apparatus for amplifying an optical signal is provided. In accordance with one example embodiment of the invention, the optical amplification system includes an optical signal traveling through the system. At least one module of the optical amplification system is suitable for one of selectively separating and combining one or more individual sub-bands of the optical signal. At least one amplifier is disposed to separately amplify each of the one or more individual sub-bands.
