Note 1: The light receiving power -1dBm, configuration 59 PAL-D analog TV channel signal within the frequency range of 550MHz, transmit digital modulated signal within 550MHz-862MHz frequency range, the level of the digital modulation signal (within 8MHz bandwidth) than the analog signal the carrier level low 10dB, the output level is 106dB, 6dB tilt.

Ordering Guide：

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!
