The F-CPL-630-N-FP Variable Ratio Coupler is an all fiber, polished directional coupler with variable coupling ratio. This device can be used to divide or combine 630 nm optical signals in fiber optics research. With its low loss and precision mechanism, the F-CPL series gives you smooth and easy control of coupling ratio. This non-PM fiber version has FC/PC connectorized fiber pigtails.
