Scalable and exchangeable erbium doped fiber amplifier for DWDM
Erbium doped fiber amplifiers for dense wavelength division multiplexed (DWDM) metro area optical networks may be configured as either high gain amplifiers or power amplifiers. The erbium doped fiber type, length, and pump power level are selected so that the shape of the gain spectra is approximately the same for single channel or multi-channel operation. In one embodiment, the same erbium doped fiber type and length is used for both power amplifiers and high gain amplifiers, reducing manufacturing costs.
