1×2 High Speed Multi-Mode Fiber Optical Switch – NanoSpeed™
100ns rise/fall, low loss, bidirectional, polarization insensitive, all wavelengthsThe NanoSpeedTM series multi-mode 1×2 solid-state fiber (MMF) optic switch connects optical channels by redirecting an incoming optical signal into a selected output optical fiber. This is achieved using patent non-mechanical configurations with solid-state all-crystal designs, which eliminates the need for mechanical movement and organic materials. The NS fiber optic switch is designed to meet the most demanding switching requirements of ultra-high reliability, fast response time, and continuous switching operation. This series of switches are bidirectional intrinsically.
The NS Series switch is controlled by 5V TTL signals with a specially designed electronic driver having performance optimized for various repetition rate.

[1] Operation bandwidth is +/- 25nm approximately at 1550nm.
[2] Measured without connector under source with CPR =13dB
[3] Cross talk is measured at 5kHz under source with CPR =13dB, which may be degraded at the high repeat rate.
[4] Defined at wavelength >1300nm. For the shorter wavelength, the handling power may be reduced, please contact us for more information.
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.
