MEMS Fiber-Optic Switches

OVERVIEW

Features

488, 633, 780, 830, 980, and 1310 nm
High Reliability MEMS Technology
Easy Mounting on Printed Circuit Boards
Low Insertion Loss: Typ 0.7 dB (except OSW12-488-SM: < 2 dB at 488 nm)

These MEMS single mode switches are designed to be easily integrated into optical systems. The highly reliable MEMS technology is characterized by a long lifetime, high reliability, and high durability (max 3 x 10⁹ cycles), making these suitable for use as OEM components. The switch is packaged to allow easy mounting onto PCB boards.

Our MEMS switches are available at 6 wavelength ranges from 488 to 1625 nm and feature low insertion losses of <0.7 dB (except OSW12-488-SM: < 2 dB at 488 nm) . The switches are non-latching and are offered as either components or as integrated systems on an evaluation board. The switches include a drive circuit requiring 5 V DC, which could be provided by the Thorlabs power supply LDS5. The OSW12 Optical Switch Kits are shipped with a power supply.
