Note 1: 59 PAL-D analog television channel signals are allocated in 550 MHz and full-band digital modulation signals are transmitted in 550 MHz-862 MHz every 2 MHz under the specified link loss. The digital modulation signal level is

10 dB lower than the analog modulation signal level, and the optical receiver input optical power is -1 dBm. The test results will be different according to the different amplification modules of the optical receiver configuration.
