摘要：

The performance of 40 channel AM-VSB video signal transmission using a P3+-doped fluoride fibre amplifier (PDFA) was examined. The PDFA improves the loss budget by 10dB for 52dB CNR, and distortion levels almost satisfy the CATV trunk line specifications. The video quality degradation after PDFA amplification was 'imperceptible' in subjective tests.
