High Power 1×3/1×4 High Speed Optical Switch – NanoSpeed™

60ns rise/fall, 500kHz, low loss, bidirectional, 850nm to 1620nm, 0 to 70 °C
Download Product Spec PDF

The NanoSpeedTM Series 1×3/1×4 solid-state fiber 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 device is intrinsic bidirectional and has variable coupler behavior in which light is transferred from one to another port without loss. 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 1×3/1×4 switch is cascade several NS 1×4.  The device is mounted on a specially designed electronic PCB and controlled by 5V TTL input signals.  A wall plug power supply in provided.   Box mounted version is an option.

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.
