Polarization Maintaining PM SMF Fiber Patch Cable 1M LC Slow Axis 1550nm online sale
PM Patch Cord
Polarization maintaining (PM) optical patch cords are widely used in polarization sensitive fiber optical systems for transmission of light that requires the PM state to be maintained. This price on the website is for 1M length,please feel free to enquiry us for the other length standard

What is PolarizationA polarized lightwave signal is represented by electric and magnetic field vectors that lie at right angles to one another in a transverse plane (a plane perpendicular to the direction of travel). Polarization is defined in terms of the pattern traced out in the transverse plane by the electric field vector as a function of time. Polarization Coordinate System
An explicit coordinate system must be specified in order to unambiguously describe a state of polarization. This is shown in the following illustration.

1.The PM fiber and the connector key are aligned to the slow axis.
2.The devices with connectors,insertion loss will be 0.3dB higher,RL will be 5dB lower,and ER will be 2dB lower.
3.The above specifications are for device without connector.
