Data sheet:

Interface: Plastic-fiber optic <> RS232 with 25-pin connector

  • FOC interface 25-pin with DTE pinout

No special tool needed for POF installation

The model 81026 Interface transmits serial RS232 data via plastic duplex fibers over a distance of up to 100 meters. The converter powers itself from the serial port and so usually requires no additional power supply.

Properties

Interfaces:

  • RS232 Interface
    • 25-pin SUB-D plug
  • Fiber optics 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

Power supply:

  • No additional power source required

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee

Worth knowing

The model 81026 Interface powers itself from the signal lines of the serial interface and requires no additional external power supply when operated on standard RS232 interfaces.

If however there are supply problems due to low-power interfaces, it is always possible to externally power the interface with up to 9V using its handshake inputs, or to use fiber-optic interfaces having their own power supply (e.g. model 81201).
