Trial conditions

Special note: The technical parameters of the equipment provided in this manual refer to GY/T 184-2002 Analog Fiber Optic Amplification for Cable TV Systems

The testing method specified in the "Technical Requirements and Measurement Methods for Instruments" shall be carried out under the following testing conditions.

Test conditions: A test link is formed with a standard optical transmitter, a standard optical receiver, and a 10km standard optical fiber. 59 PAL-D analog TV channel signals are configured in the frequency range of 550MHz, and digital modulation signals are transmitted in the frequency range of 550-750/862 MHz. The level of the digital modulation signal (within the bandwidth of 8 MHz) is 10dB lower than the carrier level of the analog signal. When the input optical power of the optical receiver is 0dBm, the carrier combination third-order beat ratio (C/CTB) is measured Carrier combination second-order beat ratio (C/CSO) and carrier to noise ratio (C/N).
