Polarization Insensitive Fiber Isolator Array (Single Stage)

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 insertion 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 multistage EDFA applications.
