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 an operating wavelength of 488, 633, 780, 830, 980, or 1310 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.
