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.
Fiber-Mart provides PM patch cords at six different wavelengths, including 780nm, 850nm, 980nm, 1060nm, 1310nm and 1550nm), with slow Axis or fast axis. Our PM patch cord features high extinction ratio, low insertion loss, high return loss and long term reliability.

This price on the website is for 1M length,please feel free to enquiry us for the other length standard

What is Polarization?

A 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.

The z-axis is horizontally oriented in the direction of propagation of the light. The y-axis is vertically oriented pointing up, and the x-axis is horizontally oriented to form a right-handed rectangular coordinate system. Angles are measured with reference to the x-axis, a positive angle indicating the sense of rotation from the x-axis toward the y-axis.(The left picture)

In the following illustration, unpolarized light is filtered by a polarizer to produce horizontal linear light. A quarter-wave retarder is used to resolve the horizontally polarized light into two equal-intensity components that travel at slightly different speeds.(The middle picture)

For the retarder orientation shown, light emerging from the retarder is right-hand circularly polarized, as seen in the right side illustration.(The right picture)


Picture Samples

Kind Note: This price is for the common PM patch cord ( slow axis, narrow key, panda type, and 1550nm wavelength.) with FC connector. We can also offer fast axis, wide key, bow-tie/elliptical type, and other wavelength like 780nm, 850nm, 980nm, ect, with other connectors like LC/SC/ST.
