High Speed Fiber Optical Resonant Switch: 10-100 MHz Fixed Rate

The resonance NS Series fiber optic switch/modulator is either a 2-port or a 3-port device featuring fast amplitude modulation at a fixed frequency with a selection from 10 to 90 MHz and low optical loss. This is achieved using a patented electro-optical configuration with a built-in high Q resonant circuit. Unlike other modulators, we use special electro-optical crystals of high stability that increase power handling and reduce drift/darkening. The NS fiber optic switch meets the most demanding switching requirements of continuous operations over 25 years and has non-mechanical ultra-high reliability. The switch is intrinsically bidirectional and selectable for polarization-independent or polarization-maintain by the fiber type. Our resonant EO phase modulators can be driven by a standard laboratory function generator with a Half-Wave Drive Voltage of only 15 V at 633 nm.
