- A 1530-nm band has been studied as pump wavelength for long-wavelength-band erbium-doped fiber amplifier (L-band EDFA). The pump source is built using a tunable light source and cascaded conventional-band (C-band) EDFA. The L-band EDFA uses a forward pumping scheme. Within the 1530-nm band, 1545-nm pump demonstrates 0.45-dB/mW gain coefficient, which is twice better than that of conventional 1480-nm pumped EDFA. The noise figure of 1530-nm pump is at worst 6.36 dB, which is 0.75 dB higher than that of 1480-nm pumped EDFA. Such high-gain coefficient indicates that the L-band EDFA consumes low power.
