English term or phrase: OSNR
However, optical transmission systems with coherent detection and optical amplification on the link or in front of the receiver are no longer shot-noise limited, but limited by the amplifier noise. Then, the dominant noise component usually is the LO-ASE noise, as discussed in Sect. 3.3.2 and shown in [3]. In the case of amplifier noise limited detection, the noise performance of coherent receivers can be characterized by the OSNR requirements in the same way as for direct detection receivers.

Optical Signal-to-Noise Ratio
Explanation:
"OSNR monitoring in optical fiber communication systems
Abstract :
Optical signal to noise ratio (OSNR) is a critical parameter that determines the performance of optical transmission system. For future smart optical networks, real-time monitoring for OSNR becomes more necessary for the system management. In this paper, we review our OSNR monitoring techniques based on RF power measurement, which is simple and cost-effective. After the optical signal and noise is detected by the square law detection, the relationship between optical signal and noise is transformed into the relationship between electrical signal and noise."
