## Abstract A new double‐pass long‐wavelength‐band erbium‐doped fiber amplifier with enhanced noise figure characteristics is demonstrated by adding a short length of forward pumped erbium‐doped fiber (EDF) in front of the double‐pass amplifier. By adding 7 m of EDF, the amplifier achieves a flat‐g
