Polarization Insensitive Fiber Isolator Array (Single Stage)
Features
Wide Operating Wavelength
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.
