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.
