Optical Isolator
Features and Benefits
Wide Optical Wavelength and Temperature Range
Low Insertion Loss
High Isolation
Epoxy Free in Optical Path
Ultra Low PDL and PMD
Corning offers single-stage and dual-stage optical isolators
which minimize back reflection and back scattering in
the reverse direction at any state of polarization. The
Polarization Insensitive Isolator (PII) is a low-cost model
with excellent performance, including low insertion loss,
high isolation, high return loss, and low PDL and PMD. It is
available in both C and L band.
