Polarization Insensitive Fiber

Isolator Array (Single Stage)

OISA Series

Oplink’s single-stage, multi-port isolator is an array device with the identical

package size of a single-port isolator. It offers port options of dual or triple

ports on both input and output sides. The Oplink isolator array minimizes

back reflection and back scattering in the reverse direction for any state of

polarization. It features low cost with high performance including low inser-

tion loss, low channel cross talk, high return loss, low polarization dependent

loss (PDL) and low polarization mode dispersion (PMD). Oplink’s innovative

array solution provides significant space savings in EDFA array or multi stage

EDFA applications.
