## Abstract L‐band gain improvement through amplified spontaneous emission (ASE) pumping was conducted. For an L‐band amplifier system employing ASE to improve gain, pumping the system counterdirectionally with ASE and codirectionally with 980 nm would yield the best overall performance in terms of

## Abstract In this article, the authors investigate and compare the gain and noise figure of various 1480‐nm pumping erbium‐doped fiber amplifier configurations to amplify 32 digital wavelength division multiplexing channel signals operated in the long‐wavelength band of 1570–1610 nm. It was found
