Standard Size Bend-Insensitive Polarization-Maintaining Fiber
This bend-insensitive PM fiber retains the reliable Panda symmetric stress structure of standard PM fiber, with optimized internal design to suppress bending loss and polarization crosstalk under small-radius winding conditions.
Description
Product Overview
This bend-insensitive PM fiber retains the reliable Panda symmetric stress structure of standard PM fiber, with optimized internal design to suppress bending loss and polarization crosstalk under small-radius winding conditions.
With standard 125μm cladding and 245μm coating, it supports R7.5 and R5 ultra-small bending radii, solving signal degradation issues caused by tight wiring inside miniaturized optical modules.
All products pass strict geometric dimension inspection, comply with RoHS & REACH, and are ideal for compact fiber optic gyroscopes, bend-sensitive sensors and high-density laser pigtail assemblies.
Key Features
- Professional anti-bending design, stable performance under R5 & R7.5 small bending radius
- Controlled macrobending loss and bending crosstalk after multi-turn winding
- Excellent polarization maintaining performance, beat length ≤3.0mm
- Fine grindability and consistent dimensional uniformity
- Dual-layer UV acrylate coating, strong tensile resistance with ≥100 kpsi proof tension
- Wide temperature adaptability from -55℃ to +85℃, full environmental certification
