Note:

1) 59 PAL-D analog TV channel signals are arranged in the 550 MHz frequency range under the specified link loss conditions, the digital modulation signal is transmitted in the frequency range of 550 MHz to 750 (862) MHz, the level of the digital modulation signal 8MHz bandwidth) than the analog signal carrier level is 10dB lower, the optical receiver input light rate of 0dBm, the measurement carrier combination

Third-order beat ratio (C / CTB), carrier combination second-order beat ratio (C / CSO) and carrier to noise ratio (C / N).

2) fiber 50KM + EDFA.
