通過比較各種隔離數(shù)字通信的特點(diǎn)和應(yīng)用范圍，指出塑料光纖在隔離數(shù)字通信中的優(yōu)勢。使用已經(jīng)標(biāo)準(zhǔn)化的TOSLINK接口，有利于節(jié)省硬件開發(fā)成本和簡化設(shè)計(jì)難度。給出了塑料光纖的硬件驅(qū)動(dòng)電路，說明設(shè)計(jì)過程中的注意事項(xiàng)，對(duì)光收發(fā)模塊的電壓特性和頻率特性進(jìn)行全面試驗(yàn)，并給出SPI口使用塑料光纖隔離通信的典型應(yīng)用電路圖。試驗(yàn)結(jié)果表明，該設(shè)計(jì)可為電力現(xiàn)場、電力電子及儀器儀表的設(shè)計(jì)提供參考。 Abstract: y comparing characteristics and applications area of various isolated digital communications， this article indicates advantages of plastic optical fiber in isolated digital communications. Using the standardized TOSLINK interface， it helps to control costs and difficulty in hardware development and design. Then it gives the hardware driver circuit of plastic optical fiber module， explains the noticed details in design process， gives results on the basis of the optical transceiver module voltage characteristics and frequency characteristics tests. Finally，it gives typical application circuit of the SPI communication port by using plastic optical fiber isolation .The results show that this design can be referenced for the power field， power electronics and instrumentation design.
