概述随着光纤通信的迅速发展,对光纤的传输性能与耦合性能要求越来越高,而目前国内光纤拉丝过程中影响上述性能的光纤外径变化在±10μM以上,与实际使用要求相差甚大。为此,我们研制了GY-A型光纤外径测量控制仪。该仪器已达到的技术指标为:/测量范围:50μM～250μM;。2测量精度:误差±0.5％以内;3.控制精度:误差±1％以内;(?)分辨力:0.1μM。
Overview With the rapid development of optical fiber communications, optical fiber transmission performance and coupling performance requirements are getting higher and higher, but the current domestic optical fiber drawing process changes in the above properties of the optical fiber outside diameter ± 10μM above, with the actual use of a very different. To this end, we have developed a GY-A fiber diameter measurement controller. The instrument has reached the technical indicators: / Measuring range: 50μM ~ 250μM ;. 2 measurement accuracy: error within ± 0.5%; 3. Control accuracy: within ± 1% error; (?) Resolution: 0.1μM.
