指导性的工业图表清楚地表明,光纤传输容量如此之大,因而要求重新考虑光纤支持系统的结构。美国Shelton的ITT先进技术中心的高锟博士5月份在伦敦的英国电子周开辟了纤维光学区域。他借此机会强调指出,光纤的性能因其带宽/距离的乘积达100GHz·km而产生了这样一种论点,即终端信号处理速度“应显著提高。”高锟博士指出,因用实验证明光纤的最高传输速率不超过10Gb/s,故目前的光纤系统能以2.24Gb/s的码速工作。这就出现两个问题:未来的光电元件能否达到10~(12)的码速:尚若可以实现,又该如何设计信号处理系统以适应这种码速?光
The guiding industrial chart clearly shows that the fiber optic transmission capacity is so great that it calls for reconsideration of the structure of the fiber support system. Dr. Kao Kun, ITT Advanced Technology Center, Shelton, USA, opened the fiber optic zone at British Electronics Week in London in May. He took the opportunity to emphasize that the performance of optical fiber due to its bandwidth / distance product up to 100GHz · km produced the argument that the terminal signal processing speed “should be significantly improved.” Dr. Kao pointed out that the use of optical fiber The maximum transmission rate does not exceed 10Gb / s, so the current fiber system to 2.24Gb / s code speed work. This raises two questions: Can the future optoelectronic components reach a code speed of 10-12? If so, how can the signal processing system be designed to accommodate this code speed?
