<p>A system and method for modular multiplexing (Fig. 2) and amplification of optical signals in subwindows within an operating window of a fiber optic communication network. An operating window is divided into subwindows. Optical signals in each subwindow are optically amplified separately and in parallel by a plurality of optical line amplifiers (210, 220, 230, 240). According to one embodiment, the operating window is divided into four (red, blue, green, yellow) subwindows within an erbium wavelength band. Each subwindow corresponds to a different group of channels having optical signals of a different wavelength. Modular wavelength division multiplexing (WDM) units (202, 262) multiplex/demultiplex optical signals in the set of multiple channels.</p> |
