Premium 30dB Extinction, Low Drift 1x1, 1x2, 2x2 Fiber Optical Switch – NanoSpeed™

SKU: NPS3

The NS Premium Series fiber optic switch uniquely features low optical loss, fast response, high on-off extinction of 30dB, little drift, and high optical power handling. This is achieved using our patented electro-optical configuration for a clean, fast response without ripples and temperature compensation, combined with our compensating electro-optical control technology that significantly reduces drift to achieve a high on/off ratio at high speed. The switch is intrinsically bidirectional and selectable for polarization-independent or polarization-maintain by the fiber type. The NSP fiber optic switch is designed to meet the most demanding switching requirements of continuous operations over 25 years. Our non-mechanical design provides ultra-high reliability and vibration insensitivity. The NSP Series switch is mounted on a specially designed PCB driver with 0-5V TTL trigger signals. The rise/fall time is intrinsically related to the crystal properties, and the repetition rate is associated with the driver. There are poor frequency response sections in the operation bandwidth due to device resonances. No optical signal loss occurs during the switching in which optical power is transferred continuously from one port to another (see graph at the end).
Our NS series switches respond to a control signal with any arbitrary timing with frequency from DC up to MHz. The switch is usually mounted on a tuned driver before shipping. The electrical power consumption is related to the repetition rate at which the switch is operated.
The device may have some drift over time when operated at a zero switching rate.
Our dual-stage configuration increases the extinction ratio or cross-talk value.
