Polarization Insensitive Fiber
Isolator Array (Single Stage)
OISA Series
Product Description
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.
