Product Overview
Winner PMW-1310 is a panda-type polarization-maintaining fiber featuring two symmetric boron-doped stress-applying parts (SAPs) that induce high linear birefringence along the slow axis. This structure effectively suppresses polarization mode coupling, delivering ultra-low polarization crosstalk (≤ -35 dB over 2 meters) and high extinction ratio in practical device assemblies.
With attenuation ≤0.8 dB/km at 1310 nm, precise mode field diameter (6.0 ±0.5 μm), and stringent geometric control, the fiber ensures low-loss splicing to standard SMF-28 or other PM components using rotational alignment fusion splicers. Its robust dual acrylate coating and ≥100 kpsi proof tension screening guarantee mechanical reliability during winding, packaging, and long-term operation in industrial environments.

Handling Notes
For optimal performance, align the slow axis (marked by stress rod orientation) during splicing and connectorization. Avoid excessive bending radii (<15 mm) to prevent induced birefringence distortion. Store and handle in clean, dry conditions to preserve coating integrity and polarization stability.
