APPLICATION

Our multi-channel high-precision FAU adopts a hybrid packaging solution combining polarization-maintaining fiber (PMF)

and standard single-mode fiber (SMF). It satisfies the comprehensive requirements of CPO systems for high density,

multi-channel transmission and polarization-stable coupling.

FEATURES

• High polarization extinction ratio

• Low insertion loss

• Low angular deviation (≤3°)

• Excellent compatibility with standard connectors

• Customizable length

• Customizable axial angles including fast axis, slow axis and other orientations as required

• Optional polarization-maintaining fibers for 850nm, 980nm, 1310nm, 1550nm and other wavelengths

• RoHS compliant
