Model 4154 Fiber Optic Repeater Application:
Copper Interface to Plastic Fiber Optical (POF) to Copper Interface

The drawing illustrates the Model 4154 POF Fiber Repeater with a DB9 copper interface connector as a monitor and two Plastic Optical Fiber Versalink connectors. The DB9 is connected to a PC / Network Analyzer. The POF Versalink connectors are linked to Video Gaming Machines. Video Gaming Machines are also linked to the two POF Fiber Optic connectors of the Model 4139. The DB9 connector of the Model 4139 is connected to the controller.

Model 4154 Application

The POF Fiber Repeater with RS232 Monitor Port is used to regenerate data signals in order to extend the range between optically linked Video Lottery Terminals. It also has the capability to monitor network traffic via an RS232 Monitor Port. The fiber optic communication standard also allows data transmission that is no longer susceptible to electrostatic or electromagnetic fields.  Additionally, the RS232 monitor port is protected from damage by potential differences (ground variations) that often exist between them.

Fiber 232® MODEL 4154 FEATURES:

  • RS232 Traffic Monitor port via a DB9 connector.
  • Provides full galvanic isolation (no metallic connection)
  • between the fiber ports and the RS232 monitor port.
  • Allows the interference-free fiber optical transfer of data to be
  • regenerated and its range extended.
  • Plastic Fiber connections via two standard Versatile Link connectors.
  • Link distance: greater than 500 meters (1640 feet) with 2.00 mm
  • Hard Clad Silicon fiber cable.
  • Provided with external wall-mount power supply, UL approved.
  • RoHS 2 Compliant
