Light from a pulsed GaAs injection laser is coupled into a glass fiber via a taper coupler. The time dependence of the light backscattered within the fiber as the pulse travels down the waveguide is recorded. From these data the total loss may be determined, as well as an estimate of the scattering and mode mixing characteristics of the fiber.
来自脉冲砷化镓注入激光器的光通过锥形耦合器耦合到玻璃纤维中。当脉冲沿着波导传播时，记录光纤内背向散射光的时间依赖性。根据这些数据，可以确定总损耗以及对光纤散射和模式混合特性的估计。
