Optical Switch Kits
Thorlabs offers a line of bidirectional fiber optic switch kits that include a MEMS optical switch with an integrated control circuit that offers a USB 2.0 interface for easy integration into your optical system. Choose from 1x2 or 2x2 MEMS modules with any of the following operating wavelengths: 480 - 650 nm, 600 - 800 nm, 750 - 950 nm, 800 - 1000 nm, 970 - 1170 nm, or 1280 - 1625 nm. These bidirectional switches have low insertion loss and excellent repeatability.
The switching mechanism is based on silicon MEMS technology, which ensures high reliability, provides exceptionally low crosstalk between channels, and is inherently very fast (switching time <1ms). These switches, which are designed for the distribution and routing of signals at the indicated visible or near infrared wavelengths, are controlled via an on-board pushbutton switch, a TTL toggle input signal, or digitally via the USB 2.0 port. A seven segment LED displays the active channel.
These optical switch kits can be powered via the USB port (4.75 V - 5.25 VDC 300 mA Max) or the onboard DC power connector (6V - 15 VDC 300 mA Max). The Thorlabs PMPS9 power supply is included.
By default, all switches are shipped without fiber connectors. Termination of the fibers is available upon request; please contact your local Thorlabs office for pricing.
*Additionally, 1x4 and 1x8 MEMS switch modules are available upon request. Please contact Tech Support for details.

Software for the OSWxx Series Optical Switches
The available software is organized into the following categories:
These 1x2 bidirectional switch kits feature one input and two outputs. They are ideal for switching between two input signals or switching a signal between two destinations. MEMS technology ensures fast switching (<1 ms), high reliability, and exceptionally low crosstalk.
These 2x2 bidirectional optical switches, which have two inputs and two outputs, feature straight and cross switching modes, where each input can be routed to one of two outputs. (1→3 and 2→4, or 1→4 and 2→3). MEMS technology ensures fast switching (<1 ms), high reliability, and exceptionally low crosstalk.
