精工仪器公司的美国光纤小组在其调制解调器系列产品中增添了一个新产品——高速调制解调器。精工公司宣称,与该公司的同类产品相比,SFC-1220型光纤调制解调器的速度要快4倍,即在符合通用接口总线标准(GP-IB)的两条总线之间以200 kb/s的速度传送数据。由于SFC-1220型光纤调制解调器用于距离为25cm～2km,必须传输大量数据的应用场所,因此它适用于工厂自动化、生产、大型计算机系统,测试仪器、长途通信系统以及局部区域网络。 SFC-1220型光纤调制解调器也适宜于高速的图像传输。据特工公司的销售工程师小松健说,
Seiko Instruments’ fiber optic team in the United States added a new product to its line of modem products - high-speed modems. Seiko Instruments claims that the SFC-1220 Fiber Modem is four times faster than comparable products of the company at 200 kb / s between two buses that comply with the General Purpose Interface Bus Standard (GP-IB) Speed transmission of data. The SFC-1220 is suitable for use in factory automation, production, mainframe computer systems, test equipment, telecommunication systems, and local area networks because it is used in applications where large amounts of data must be transmitted over a distance of 25cm to 2km. The SFC-1220 Fiber Modem is also suitable for high-speed image transmission. According to the company’s sales engineer Komatsu Kin said,
