Where to Buy Fiber-optic Attenuators
Fiber-optic attenuators are used to reduce the optical power propagating in a fiber. Available with various fiber connectors, they can be used to prevent excessive signal power from reaching photodetectors and other sensitive components, thus protecting them and ensuring accurate signal processing.

 Optics, Photonics and Metrology Kieler Str. 212 22525 Hamburg Germany |  The laser attenuator 48AT-0 is used for reproducible and precise reduction of the power output by the laser. The collimated laser beam is constricted by a precision ball transported by a scaled micrometer screw. The subsequent single-mode fiber coupling is used as a mode filter. |
 DK Photonics Technology Co., Ltd. 4F, Building 18, Qinghu Industrial Park Dahe Road, Longhua District Shenzhen, Guangdong 518109 China ISO 9001:2015, ISO 14001:2015 |  Our polarization-maintaining mechanical variable optical attenuator is a useful tool for tests of optical components and systems. All input and output fibers are polarization maintaining, and devices for a wide range of wavelengths are available. The devices feature a low minimum insertion loss, high extinction ratio, high return loss and high adjustment precision. |
