SKU: NFSM
The NS Ultrafast Series fiber-optic switch delivers low insertion loss, ultrafast response, and high optical power handling. The NFSM model cascades two switching elements on an integrated driver to achieve ~28 dB on-off extinction, using a patented electro-optical architecture that provides clean, ripple-free switching and stable temperature performance. The device is intrinsically bidirectional and offered in either polarization-independent or polarization-maintaining fiber configurations. Designed for continuous 24/7 operation over 25 years, the solid-state non-mechanical design ensures exceptional reliability and immunity to vibration and shock. Each NFSW switch is supplied on a dedicated PCB driver with a single 0–5 V TTL trigger input and a DC power supply for plug-and-play integration. The optical rise/fall times are governed by the electro-optic crystal response, while the maximum switching repetition rate is determined by the driver electronics. As with all resonant electro-optic structures, narrow frequency regions of reduced modulation efficiency may appear within the usable bandwidth. Optical power is transferred continuously between output ports during switching, ensuring no interruption to the optical path. The NS Ultrafast Series accepts arbitrary control waveforms from DC to the MHz range, and power consumption scales with switching frequency.
