Product Overview
Fabricated using the Modified Chemical Vapor Deposition (MCVD) process, this standard panda-type PM fiber features a germanosilicate core surrounded by two boron-doped stress-applying parts (SAPs) that generate high linear birefringence. This structure effectively locks the polarization state of launched light, achieving polarization crosstalk of ≤ -28 dB over 1 meter at 1310 nm.
With a conventional 245 μm dual acrylate coating and precise 125 μm cladding geometry, the fiber offers excellent handling robustness, low microbending sensitivity, and compatibility with standard fusion splicers equipped with rotational alignment. Its low attenuation (≤0.8 dB/km) and tight mode field diameter control (6.0 ±0.5 μm) ensure minimal insertion loss in pigtailed devices and sensor assemblies.

Integration Guidance
For optimal polarization extinction ratio (PER), align the slow axis (indicated by SAP orientation) during splicing using a rotational fusion splicer. Maintain bend radii >15 mm to avoid induced birefringence distortion. The standard 245 μm coating ensures compatibility with commercial fiber handling tools, connectors, and protective sleeves.
