Zusammenfassung:	A high-linearity cable TV transmission technique using optical fibre features that after inverted, multi-channel TV signals become normal and inverted TV signals respectively used to modulate laser device; after transmission over optical fibre, modulated TV signals are demodulated by photoelectric diode and amplified by push-pull amplifier. Its advantages include high linearity and power, low cost and reliable performance.
