80um 1550nm Polarization Maintaining Isolator
The 80um 1550nm Polarization Maintaining Isolator is a two port micro-optic device built with PM panda fiber. It is made of 80um core RC fiber. The PM isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction. The device can be built with bare fiber, or 900um jacket cable. The PM Panda Fiber Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.
If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.DK Photonics can respond to custom requirements with short lead times.
