Product Details
Free Space Isolator Single Stage or Dual Stage
Description
The Free Space Isolators are used in various TOSAs, which require isolation to prevent feedback into the laser. This product is available in single and double stage designs. The Free Space Isolator offers excellent performance with low insertion loss and high isolation. It guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction at any polarization sate.The unique manufacturing process and optical path epoxy-free design enhance the device's high power handling capability. The devices are characterized with high performance, high reliability and low cost. It has been widely used in EDFAs, Raman amplifiers, DWDM systems, Fiber lasers, transmitters and other fiber optic communication equipments to suppress back reflection and back scattering.
Except free space optical isolator, PM Isolator & High Power Isolator & Polarization Insensitive Isolator or other customized configuration are also available upon request.
