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. |
