我们研制了一种中央处理机(CPU)和外设备之间的光纤传输小型计算机接口。数据字长20bit,传输速率10Mbit/s。光缆由20根突变光纤组成,可长达120米。把光电转换器件(即LED和单片集成光电二极管接收器)装配在配线的有源连接器里并牢固地固定好相应的光纤端子。连接器的插针导通TTL信号。这种光接口比通常的电接口体积小得多。在该计算机系统中,接口和设备之间用多芯导线连接,它们包括多脚连接器,驱动器、接收器集成片以及印刷电路板(PC)。通常五个IC中有一个是接口电路。这些连
We developed a small computer interface for optical fiber transmission between a central processing unit (CPU) and an external device. Data word length 20bit, transfer rate 10Mbit / s. The cable consists of 20 abrupt fibers, which can be as long as 120 meters. The photoelectric conversion devices (ie, LEDs and monolithically integrated photodiode receiver) are mounted in a wired active connector and the optical fiber terminals are securely fastened. The pins of the connector turn on the TTL signal. This optical interface is much smaller than the usual electrical interface. In this computer system, interfaces and devices are connected by multi-conductor cables, including multi-pin connectors, drivers, receiver chips, and printed circuit boards (PCs). Usually one of the five ICs is an interface circuit. These companies
