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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
