POF - Polymer Optical Fiber

Polymer Optical Fiber

With polymer optical fibers (POF), both the fiber core and the cladding is manufactured from a polymer. Superior flexibility (high alternate bending loads with smaller bending radiuses), connection and transmission technology that is less expensive than silica-based systems, and simple assembly in the field are key advantages of polymer optical fibers.

  • 100% final inspection to verify optical attenuation in high-volume production
  • Economical connector systems and transmitters/receivers
  • Fast, straightforward assembly technology
  • Superior flexibility (high alternate bending loads with smaller bending radiuses)
  • Can be assembled in the field (prior experience is useful but not required)
  • We can also supply the various tools required

Further information

WEINERT Fiber Optics performs a 100% final inspection to verify optical attenuation on all POF cables in high-volume production. This enables us to guarantee first-class quality for our products. Measuring attenuation on complete cable drums (250 and 500 m) is a particular challenge, due to the high optical attenuation of the POF. WEINERT uses a measurement system specially developed for this purpose with an extremely high attenuation budget at 650 nm.

The maximum application temperature for standard POF is limited to 85 °C by the cladding material. By using a different cladding material, thermal stability can be increased to 105 °C. However, this also increases the kilometric attenuation slightly. The PMMA core material is the limiting factor for even higher temperatures.

The numerical aperture of the fibers can be changed by using other cladding materials. High-NA POFs, i.e. fibers with a higher increased numerical aperture, permit higher power coupling in the fiber. Increasing the NA results in a lower bandwidth, however.
