The F-CPL Series Variable Ratio Couplers are an all fiber, polished directional coupler with variable coupling ratio. These devices can be used to divide or combine 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. Polarization maintaining (PM) and non-PM fiber versions are available. Available wavelengths include 630 nm, 830 nm, 980 nm, 1060 nm, 1300 nm, and 1550 nm.
