Remark:
* Above specifications are for devices without the connectors.
* For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
* The PM fiber and the connector key are aligned to the slow axis. fast axis is blocked.


Features: Wide passband and 20nm channel spacing
Features: Excellent polarization extinction ratio (ER) and single-axis alignment mechanism
Features: Cascaded Optimized Low Insertion Loss Architecture
Features: Excellent isolation and high optical power handling capability
3.Applications
  • Multi-point Fiber Sensing: Combines FBG or BOTDA technology to separate polarization probe light of different wavelengths.
  • Cost-Effective Coherent Telecom: Polarization multiplexing expansion based on CWDM architecture in edge networks.
  • Biomedical and OCT Imaging: Parallel processing of multi-band interferometric signals under broadband light sources.
  • Fiber Amplifier Testing and Measurement: Provides multi-wavelength combining sources for polarization-maintaining erbium-doped/Raman amplifiers in laboratory environments.
