Polarization-Maintaining Patchcord
Products Position: Home > Products > Polarization-Maintaining Patchcord   

As a special optical fiber, polarization-maintaining fiber patchcord transmit polarized light signals, which can ensure that the direction of linear polarization is unchanged, improve the coherent signal-to-noise ratio, and achieve high-precision measurement.


Raysung Photonics Inc. adopts PANDA-type polarization-maintaining fiber and provides different fiber types and selects imported, high-precision optional connectors and ceramic ferrules. Each polarization-maintaining fiber patchcord is carefully manufactured using the most stringent process to ensure high return loss and high polarization extinction ratio, meets the industry's highest quality standards. Also, we provide customized services to customize patchcord products that meet various application needs from customers.





  • Low insertion loss and high return loss
  • High polarization extinction ratio
