Oplink’s OISS is a single stage optical isolator that minimizes back reflection

and back scattering in the reverse direction for any state of polarization.

The OISS is a low cost model with excellent performance including low

insertion loss, high isolation, high return loss, low polarization

dependent loss (PDL) and low polarization mode disper-

sion (PMD). This products excellent characteristics

make it highly suitable for laboratory and

field applications.
