Product information "VBS-22 Evanescence-Based Variable Split Ratio Fiber Splitter/Coupler"
400-2000 nm; Splitting/Coupling Ratio 0-100%; Insertion Loss <0.1, 0.5 dB; Polarization Extinction Ratio >18, >20 dB; Fiber Type SM, PM
OZ Optics’ VBS-22 evanescence based variable split ratio fiber splitter provides splitting ratios tunable from 0% to 100% with negligible optical loss. The device consists of two side-polished fibers mated to induce evanescent field coupling. The coupling ratio is controlled by adjusting the distance between the cores of the two side-polished fibers. PM fiber models with customer specified birefringence axis alignment are available.
