摘　　要：根据电压/频率转换和频率/电压转换的原理,采用LED—PIN光传输结构和相应的模拟集成电路,设计了一个低成本,传输精度可达0.1%的模拟信号光纤传输系统。该系统克服了实际传输模拟小信号的非线性,以及模拟信号A/D转换后采用数字光纤传输技术的成本较高等缺点,为多通道、远距离、低频模拟小信号提供了一个性能优越的传输方案。Based on the principles of voltage-frequency conversion and frequency-voltage conversion,with the use of LED--PIN optical transmission structure and corresponding integrated circuits, the development of an analog-signal optical fiber communication system with low cost, and transmission precision reached 0.1% has been successfully achieved. This system solves disadvantages such as the nonlinear distortion of weak analog-signal＇ S transmission; the greatly high cost of A/D converter digital optical fiber transmission technology and so on. It provided a predominant transmission scheme for multi-channel ,long distance and low-frequency weak analog-signal.
