Abstract
In this contribution, a two stage L-band Erbium-doped fiber amplifier in double-pass configuration is presented. This
amplifier provides gain as high as 44 dB with almost 45 nm flat bandwidth in L-band. Erbium-doped fiber of length 15 m is
used in first stage and second stage utilizes 70 m Erbium-doped fiber. Pump powers are 52 mW and 143 mW respectively.
In comparison to a single-pass amplifier, this amplifier shows a gain enhancement of about 14 dB and noise figure penalty
is about 2 dB.
Keywords
L-band, Erbium-doped fiber amplifier and double-pass configuration.
