Model 4131 POF Plastic Optical Fiber to USB Converter
Overview
The Model 4131 Versalink POF Fiber-to-USB Converter connects Universal Serial Bus (USB) communications to Versalink Plastic Optical Fiber (POF) core cable by supporting USB full-speed data transfer (up to 12 Mbps) from a USB host/device allowing interference-free fiber optical transfer of data between the devices.
-
Ideal for when Fiber Transmission is Needed to Reduce Noise/Grounding Surges from the Network.
-
Provides Full Galvanic Isolation (No Metallic Connection) between Connected Devices.
-
Conversion to a Fiber Optic Communication Standard Allows Data Transmission that is No Longer Susceptible to Electrostatic or Electromagnetic Fields.

Model 4131 Interface Converter Application:
The Versalink (POF) Fiber-to-USB Converters are used to connect fiber optic linked terminals to a controller having a USB Host interface port. While USB is a versatile communication standard, conversion to a fiber optic communication standard also allows data transmission that is no longer susceptible to electrostatic or electromagnetic fields. Additionally, the ports of the connected terminals are protected from damage by potential differences (ground variations) that often exist between them.
VERSALINK (POF) FIBER / USB CONVERTER APPLICATION FOR CASINO NETWORKS LINKING VIDEO LOTTERY TERMINALS & VIDEO GAMING MACHINES:
The illustration shows a Controller connected to the Model 4131 USB port and Video Gaming Machines linked to the Versatile Plastic Optical Fiber (POF) Link connectors via Versatile Link Plastic optical fiber Core Cables.

Why Use the Model 4131 POF USB Converter?
- Your main controller/device may have a USB interface and you may have to run POF Fiber Optic cables to devices or machines in a noisy environment.
- Your application needs galvanic isolation or fiber cabling for noise/grounding surges (which fiber offers).
- The data rate (12 Mbps) is sufficient for your application.
- The fibre link characteristics (distance, cable type) meet your installation environment.
- Your application requires a point-to-point USB link rather than a network-of-many–nodes scenario.
