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.

Hi, I have purchased a OSW12-780-SM with the optical switch kits. Is it possible to drive the OSW12 directly using my own TTL signal and bypass the switch kit all together? Thanks, Alex Shek Trex Enterprises 10455 Pacific Center Ct San Diego, CA 92121 Tel (858)646-5300 x 5485 Fax (858)646-5301 Email: ashek@trexenterprises.com

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. If you are using the Fiber Optic Switch Kit OSW12-780E than it is possible to remove the OSW12-780-SM from the circuit board and use your own TTL signal. You can unsolder the OSW by yourself or we can perform the modification for you. I will contact you directly to discuss the details.

Hi, I have a MEMS Switch but I'm not sure which wavelength model it is. The label on the switch says: Thorlabs SN1x2-5N MEMS Switch 2007-28-4967. The Manual is for the models: OSW12-xxx-SM (-E) Thanks!
