 Polarization Insensitive Fiber Isolator - Single Stage (PIFI-SS)

 

Description:

 

The polarization insensitive fiber isolator (PIFI) eliminates back reflection and back scattering of optical signals for any state of polarization. This single stage (SS) version provides high isolation, very low insertion loss, high isolation , high return loss, very low polarization dependent loss, very low polarization mode dispersion, and very high thermal stability in a compact design.  

 

 

Applications:

 

         Optical amplifiers (EDFA)

         CATV fiber optic systems

         Satellite communications

         Fiber laser

         Optical tests and instrumentation

 

 

Key Features:

 

         High isolation

         Low loss

         High thermal stability

         High return loss

         Low PDL

         Low PMD

         Stable and reliable performance

         Compact inline package, 5.5mm OD
