Precautions：
1, the input optical power range -7dBm ~ + optical AGC range is 2 dBm optical receiver optical input power can cause different C / N of the change. If the optical power is too high, it will damage the light-receiving PIN diode or cause greater distortion. If the optical input power is too small, it will make the C / N was significantly deteriorated. -1dBm Optical power input, CN≥51dB; -5dBm optical power input, CN≥48dB; -7dBm optical power input, CN≥46dB.
2, recommended that the input optical power of not less than -5dBm!
