1064nm Polarization Maintaining FBT Coupler
OPTICO's PM1064 FBT Coupler is a high-quality polarization-maintaining fiber coupler designed specifically for applications operating at the 1064nm wavelength. Engineered with advanced fused biconical taper (FBT) technology, this coupler ensures precise signal splitting while maintaining the polarization state, delivering superior performance and reliability in demanding optical systems.
The PM1064 FBT Coupler is ideal for laser systems, optical sensing, and high-precision communication networks. Its low insertion loss, high extinction ratio, and customizable features make it the perfect choice for applications requiring stable and reliable polarization-maintaining performance.
Key advantages
- 1064nm Wavelength Optimization: Specially designed for applications requiring exceptional performance at the 1064nm wavelength.
- Polarization Maintenance: Maintains the polarization state throughout signal splitting, essential for high-precision optical systems.
- Low Insertion Loss: Typical insertion loss ≤ 0.2dB, minimizing signal power loss and enhancing system efficiency.
- High Extinction Ratio: With extinction ratios ≥ 23dB, the coupler suppresses undesired polarization modes, ensuring clean signal transmission.
- Customizable Coupling Ratios: Offers standard options like 50:50, 90:10, and 10:90, with tailored configurations available upon request.
- Robust Packaging: Available in compact and durable packaging options, including bare fiber, stainless steel tube, and ABS box, for various integration needs.
- Thermal and Environmental Stability: Operates reliably across a wide temperature range (-40°C to +85°C), suitable for diverse and challenging environments.
