勘斯塔(Canstar)已经设计并研制了各种耦合系数的三端四端甚至多端星形耦合器。而且通过熔融双圆锥精加工工艺已经达到了成本低、可靠性好的要求。勘斯塔耦合器是供突变型和渐变型折射率光纤使用而设计的,被加工成能应用于工业环境中。该器件封装在一个坚固的外壳中。并带有50厘米长的引出线,以便与纤维光学系统进行连接。 Canstar has designed and developed a variety of three-end, four-terminal or even multi-terminal star couplers with coupling coefficients. And through the melting double cone finishing process has reached a low cost, good reliability requirements. The Galta coupler is designed for use with both mutant and graded index fibers and is engineered to be used in industrial environments. The device is housed in a rugged case. With a 50 cm lead-out for connection to fiber optics.
