POF repeater Industry

  • FO repeater, Industry

Connections over long POF distances

The FO Repeater receives light signals, prepares them and sends them back out amplified on the output. By dividing the fiber optic line into several segments POF can also be used to bridge a distance of over 100 meters.



  • 2 x FO interface
    • Direct connection of the fiber optic cable without a connector
    • Alternate names: POF (polymer optical fiber, plastic optical fiber)

Management and connectivity:

  • The interface is very easy to install:
    • Cut the fiber-optic cable with a sharp knife at right angles.
    • Insert into patented adapter of the W&T interface.
    • Plug the adapter into the PC.
    • That’s it!
  • No re-configuration of transmission parameters required
  • 100% protection against interfering radiation
  • Electrical isolation
  • Lightning protection

Voltage supply:

  • External
    • 12V-24V AC/DC via plug-in screw terminal

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

Worth knowing

The main advantages of plastic optical fiber cables over conventional glass fiber lines are the lower costs for material and the simple installation. Unfortunately, the attenuation of plastic optical fiber cables is considerably higher than that of glass fibers, so that the max. possible transfer distance is only approx. 100 m for physical reasons.

Problems in connection with higher attenuation can be avoided by dividing a long fiber-optic line into short segments with a maximum length of 100 m and by installing one or more repeaters. The repeater regenerates and amplifies the received signals and feeds the data at original intensity level through the fiber.
