Thorlabs OSW12-1310-SM-E Optical MEMS Switch

Description:

The Thorlabs OSW12-1310-SM-E Optical MEMS Switch is used in fiber optic communication and photonics systems to route optical signals between two single-mode fiber paths using MEMS switching technology with low insertion loss and high reliability. Commonly installed in optical communication networks, fiber optic test systems, telecommunications laboratories, photonics research facilities, and OEM optical instrumentation operating in the 1280–1625 nm wavelength range. Optical engineers, laboratory technicians, and system integrators use this MEMS switch for optical signal routing, network redundancy, automated testing, and replacement of fiber switching modules.

Applications:

The Thorlabs OSW12-1310-SM-E provides fast, bidirectional switching of single-mode optical signals using a non-latching MEMS mechanism. It is designed for automated optical path selection, fiber network protection, optical measurement systems, telecommunications equipment, wavelength routing, and laboratory automation where low optical loss, high repeatability, and long operational life are required.
