我院工厂和晶体生长设备研究所,从一九八一年起开始研制新一代的SJ81-4型光导纤维拉丝炉,样机于今年六月研制成功,七月在西安通过技术鉴定。光导纤维是用高纯玻璃制成的。它具有非常低衰减特性,载有信息的光束可以在光导纤维中传输很远而无需加以放大,它是今后通信传输的重要媒介。 SJ81-4型拉丝炉,采用对辊拉丝,可以拉制直径50～200微米的光导纤维;具备拉丝张力测定仪及收丝同步保持器,可对相应的控制参数进行反馈控制;配置测取光仪,可以对
Our factory and crystal growth equipment institute started to develop a new generation of SJ81-4 optical fiber drawing furnace from 1981. The prototype was successfully developed in June this year and passed the technical appraisal in Xi’an in July. Optical fibers are made of high purity glass. It has a very low attenuation characteristics of the information-carrying beam can be transmitted in the optical fiber far away without amplification, it is the future of communication and transmission of important media. SJ81-4 drawing furnace, the use of roller drawing, drawing 50 to 200 microns in diameter of optical fiber; with drawing tension tester and wire synchronization holder, the corresponding control parameters can be feedback control; configure the measured light Instrument, can be right
