Patent ID: 7088498

Claim:
An optical amplifier system for a Coarse Wavelength Division Multiplexing (CWDM) network, the optical amplifier system comprising: a first optical amplifier having a fluoride-based optical fiber of a first length, the first optical amplifier being configured to receive optical signals for a plurality of CWDM channels and to amplify the CWDM channels, wherein a higher gain is generated for longer wavelengths of the CWDM channels; and a second optical amplifier having a fluoride-based optical fiber of a second length, the second optical amplifier being configured to receive the optical signals and to amplify the CWDM channels, wherein a higher gain is generated for shorter wavelengths of the CWDM channels; wherein the first optical amplifier and the second optical amplifier are configures to generate a continuous gain bandwidth of at least 80 nm to amplify the CWDM channels.
