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 dispersion (PMD). This products excellent characteristics make it highly suitable for laboratory and field applications. |
