Remark :  Measured by standard laser transmitter, the circuit is formed with 10km fiber and optical attenuator, optical received power is -6dBm. Frequency ranges at 550MHz, according to Chinese standard configure 59 PLA-D television channels. 33 QAM64 digital channels are arranged at 550-860MHz bandwidth, and the level is lower 6dB than analogue carrier. RF output signal slope is 9dB (860MHz), RF output signal level is 106dBuV.
