传输系统的研制东京芝浦电气公司研制了采用光缆方式的成套设备控制用的高速控制信号传输系统“TOSLINE-8000”。该系统把控制各种装置(作为成套设备组成部分的可编程序控制器、控制计算机、显示装置、传感器、驱动装置等)的信号转变为光信号,并对信号之间的相互传递进行控制。其信号传输速度为每秒30兆比特,作为过程控制用的光信号传输控制系统来说,可称得上是一种最高速的控制信号传输系统。另外,与原来采用金属电缆的系统相比,由于光缆的高速、宽频带特性所带来的多路化特性,使得成套设备中所用的控制电缆的总长度约减少一半,在用光缆替代的地方,电缆的
Development of Transmission System Tokyo Shibaura Electric Co., Ltd. developed “TOSLINE-8000”, a high-speed control signal transmission system for controlling complete sets of equipment using optical fiber cables. The system converts signals that control various devices (programmable logic controllers, control computers, displays, sensors, drives, etc., that are part of a complete plant) into optical signals and control the transfer of signals between them. The signal transmission speed of 30 megabits per second, as the process control with optical signal transmission control system, can be regarded as a kind of the highest speed control signal transmission system. In addition, compared with the original system using metal cables, the total length of the control cables used in the complete equipment is reduced by about half due to the multiplexing characteristics of the high-speed and broadband characteristics of the optical cables. Where optical fiber cables are used instead , Cable
