We demonstrate an opto-optical gain-clamped L-band erbium-doped fiber amplifier by manipulating the C-band lasing wavelength as the control signal. The L-band gain-clamped value is achieved by tuning the control laser in the C-band wavelength range that propagates in the opposite direction to the L-band signal. Within the wavelength range of $1538\mathrm{nm}$ and $1560\mathrm{nm}$ , the L-band gain decreases linearly with the increment of the C-band lasing wavelength. The L-band gain dynamic range decreases with the increment of the cavity loss. By combining two different levels of cavity loss, the gain dynamic range of $10\mathrm{dB}$ from $11\mathrm{dB}$ to $21\mathrm{dB}$ is achieved with an average noise figure of less than $5.9\mathrm{dB}$ . The whole gain spectrum of the L-band can be used for multiple-channel amplification because the laser is created outside its signal band.
