OISA155000D3111 Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – Mini Single Stage Dual Optical Isolator (C or L Band)

Mini Single Stage Dual Optical
Isolator (C or L Band)
Mini OISA Series
Product Description
Oplink’s Mini Dual Isolator minimizes back reflection and back scattering in the
reverse direction for any state of polarization. The Mini Dual Isolator works as
two individual fiber isolators with excellent performance including low insertion
loss, high isolation, high return loss, high Crosstalk between different channels,
low polarization dependent loss (PDL) and low polarization mode dispersion
(PMD) with extremely compact size. Reduced cladding fiber pigtail package op-
tion is available.
