Dicon PM-1X12-13-15-9-FC

The Dicon PM-1X12-13-15-9-FC is a polarization-maintaining 1×12 MEMS optical switch that routes light from a single input fiber to any of twelve output fibers using an electrostatically driven mirror. The device operates bi-directionally, functioning as either a 1×12 switch or 12×1 selector. Non-latching architecture enables precise optical path control across dual-band wavelength ranges with minimal insertion loss and excellent crosstalk suppression.
