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

SKU: NFS3

The NS Ultrafast Series (NFS) 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 patented electro-optical configuration of clean fast response without ripples and temperature compensation in combination with drift-cancelation electro-optical control technology achieving 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 NFS fiber optic switch is designed to meet the most demanding switching requirements of continuous operations over 25 years. The non-mechanical design provides ultra-high reliability and vibration insensitivity. The NSU 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 the 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).
The NS series switches respond to a control signal of any arbitrary form with frequency from DC up to MHz. The switch is usually mounted on a tuned driver prior to shipping. The electrical power consumption is related to the repetition rate the switch is operated. The device is designed to operate at a repetition rate over 20Hz. When the device is at static, some level of drift occurs over time that reduces the on/off ratio.
