摘　　要：利用光纤传输信号抗干扰、高速率、低损耗、远距离传输的优点,通过频率调制技术,采用高集成度和耐高温、高压的集成电路以及光探测和发光器件,开发出了小型化、高集成度和高质量的视频光纤传输系统。该视频光端机可明显改善利用同轴电缆和双绞线传输视频图像达到的效果,信噪比高,失真小,且能够适时、准确地观测到石油开采过程中的井下状况,尤其是液体的浑浊程度,以便确定油层的分布状况。体积小,可灵活在深井里作业。A new minitype, high-integration and high-quality video transmission system via optical fiber is developed by the frequency modulation technique making use of the good qualities of optical transmission such as anti-jamming, high rate, low loss and long distance transmission. This sort of video optical terminal can improve the effect of video transmission via coaxial-cable and twisted-pair, high Signal-to-Noise, low distortion, and can monitor the situation of down-hole in the oil exploitation timely and truly, especially the turbidity degree of the liquid so as to confirm the distributing status of oil layers. The bulk of video optical terminal is so small as to work neatly in the down-hole.
