Product Overview
Built on a robust MCVD platform, this fiber incorporates boron-doped stress-applying parts (SAPs) symmetrically positioned around a germanosilicate core to generate high linear birefringence. It achieves exceptional polarization crosstalk of ≤ -35 dB over 2 meters—translating to a polarization extinction ratio (PER) >25 dB in practical device assemblies—ensuring signal fidelity in polarization-sensitive systems.
The fiber features a reinforced 165 μm dual-layer acrylate coating, providing enhanced mechanical durability during grinding, polishing, and taper-pulling processes common in pigtail and micro-optic fabrication. Despite its ruggedized design, it maintains low attenuation (≤0.8 dB/km) and excellent geometric uniformity, enabling consistent rotational splicing and high yield in automated production lines.

Applications
- Pigtailed laser diodes requiring polarized output in telecom and sensing
- Polarization-maintaining fiber couplers and splitters for interferometric systems

Processing Recommendations
For optimal PER retention, align the slow axis (marked by SAP orientation) during splicing using a rotational fusion splicer. The 165 μm thick coating provides excellent resistance to abrasion during polishing and facilitates secure epoxy bonding in metalized packages. Ideal for high-reliability industrial and defense-grade optical subassemblies where long-term polarization stability is non-negotiable.
