Single
Polarization Fiber Isolator - Single Stage (SPFI-SS)
|
Description: The
polarization maintaining (single polarization) fiber isolator (SPFI)
eliminates back reflection
and back scattering of optical signals in the transmitted
polarization and maintains the polarization of the input light at
high extinction ratio. This single stage (SS) isolator features high
isolation, very low insertion loss, high extinction ratio, high return
loss, and very high thermal stability in a compact design. |

Polarization
Maintaining (Two
Polarizations)
Fiber Isolator (PMFI)
|
Description: The
polarization maintaining (PM) fiber isolator (PMFI) is a true PM
isolator. It simultaneously transmits two orthogonal polarizations and eliminates
the back reflection and back scattering in the two orthogonal
polarizations simultaneously (i.e. it is a true PM isolator as
compared to single polarization isolators). It maintains the
polarization of the input light with high extinction ratio in both polarizations. It features
low insertion loss, high isolation, high extinction ratio, high
return loss, and high stability in a compact design. |
