What is the effect of ASE Noise Power?

ASE tends to limit the gain achievable in a single stage of a fiber amplifier to the order of 40–50 dB. Even if ASE in an amplifier is not strong enough to extract significant power, it can contribute significantly to the noise of the amplified signal. ASE noise may limit the effective amplification due to saturation effect and affects the receiver’s bit error ratio (BER).
