日本三菱Rayon公司己把耐热塑料光纤投入美国市场。这种于1985年11月开始生产的新光纤,虽然常规等级只推荐用于85℃,但在干燥环境下耐热能达115℃和125℃。应用场合包括汽车发动机罩下面部位以及运输业中曾因温度关系己限制使用塑料光纤的另一些部位。三菱公司希望这种光纤将来能在为工厂自动化的计算机数据网络累统和传感系统中得到应用。目前销售的耐热光纤有二种类型。DH光缆的耐热达115℃,在650nm(准直光)时,衰减<350dB/km;
Japan’s Mitsubishi Rayon has put heat-resistant plastic optical fiber into the United States market. The new optical fiber, which began production in November 1985, has a heat resistance of 115 ° C and 125 ° C in a dry environment, although the conventional grade is only recommended for use at 85 ° C. Applications include other areas under the bonnet of the car and restrictions on the use of plastic optical fiber in the transport industry as a function of temperature. Mitsubishi hopes that such optical fibers will find application in the future for automated, computer-based data acquisition and sensing systems in the factory. There are currently two types of heat-resistant optical fibers for sale. DH cable heat up to 115 ℃, at 650nm (collimated light), the attenuation <350dB / km;
