Abstract
We present experiments of line and parallel configurations of hybrid erbium-doped fiber amplifiers/fiber Raman amplifiers (EDFAs/FRAs). For the line structure, a gain flatness of ±1.15 dB over a range of 47 nm (1483 to 1530 nm) is obtained. In the parallel configuration, the gain flatness is below ±2 dB for 1487 to 1507 nm and 1520 to 1550 nm. Using a high-birefringence fiber loop mirror as a signal reflector, a noise figure is less than 6 dB in the gain bandwidth. Then performances of different hybrid configurations are compared.
