The partial double-pass L-band erbium-doped fiber amplifier with enhanced gain characteristic is demonstrated using a band pass filter (BPF). The BPF is incorporated in the double-pass route to suppress the amplified spontaneous emission from the single-pass output for gain enhancing. The gain of 51

## 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

## Abstract A new gain improvement technique for L‐band EDFA is presented. It uses an unpumped EDF in a double‐pass configuration in order to effectively suppress and completely exploit the backward ASE. Compared to a conventional single‐pass amplifier, the gain coefficient can be improved from 1.5
