Premium 1×1, 1×2, 2×2 High Speed Fiber Optical Switch – NanoSpeed™

50ns Rise/Fall 1MHz Repetition Rate, 400nm to 2000nm, -30 to 85 Degree C

The NS Premium Series solid-state fiber optic switch connects optical channels by redirecting an incoming optical signal into a selected output optical fiber at high speed. This is achieved using a patented electro-optical configuration featuring clean fast response without ripples. The NS fiber optic switch is designed to meet the most demanding switching requirements of continuous operations over 25 years and non-mechanical ultra-high reliability.

The NP Series switch is controlled by 5V TTL signals with a specially designed electronic driver having performance optimized for various repetition rate.

Q: Does NS device drift over time and temperature?
A: NS devices are based on electro-optical crystal materials that can be influenced to a certain range by the environmental variations.  The insertion loss of the device is only affected by the thermal expansion induced miss-alignment.  For extended temperature operation, we offer special packaging to -40 -100 0C.   The extinction or cross-talk value is affected by many EO material characters, including temperature-dependent birefringence,  Vp, temperature gradient, optical power, at resonance points (electronic).  However, the devices are designed to meet the minimum extinction/cross-talk stated on the spec sheets.  It is important to avoid a temperature gradient along the device length.

Q: What is the actual applying voltage on the device?
A: 100 to 400V depending on the version.

Q: How does the device work?
A: NS devices are not based on Mach-Zander Interference, rather birefringence crystal’s nature beam displacement,  in which the crystal creates two different paths for beams with different polarization orientations.

Q: What is the limitation for faster operation?
A: NS devices have been tested to have an optical response of about 300 ps.  However, practical implementation limits the response speeds.    It is possible to achieve a much faster response when operated at partial extinction value.  We also offer resonance devices over 20MHz with low electrical power consumption.

Q: Can I remove the device and remount it differently with wires?
A: You can remove the device and remount differently
1. Please use silver or gold-coated copper wires for high-speed operation.
2. Please keep the device terminally insulated from uneven temperature source
3. Please keep the output driver chip, which gives a sharp rise and fall.  We glue the chip to a copper block and to a large heat sink with a fan if you can make thermal contact with a metal chase that will be preferred.
