Overview

Interface Converters, Glass Fiber to Copper Interface
Model 4165 High Speed Ruggedized ST Fiber-to-USB Interface Converter, Desktop enclosure

  • Popular Application: Isolated PC USB Communications to Fiber Serial Interface Network.

Model 4165 High Speed Ruggedized ST Fiber to USB Interface Converter

 Model 4165, (Desktop enclosure) ST Fiber-to-USB Interface Converter with integrated rate buffering convert USB 2.0 compliant data rate from a standard PC to a serial asynchronous data interface over fiber with a user-selectable baud rate of up to 3 Mbps. This converter is ideal for high speed, secure communications, and optical isolation. 

Typical applications:

  1. Constructing an optically isolated point-to-point communications link between the USB ports of two PC's.
  2. Constructing an optically isolated high-speed communication link between a PC and a serial data network that is subject to high EMI environment that might corrupt communications over copper interface.

The Model 4165 Unit features ESD protection circuitry on the USB I/O connector. The power input is protected from transients and features 3kVDC isolation to prevent system ground loops. The Model 4165 converter can be powered from a wide input range of 10VDC-36VDC. Models are available for other voltage ranges such as 4.5VDC-9VDC and 19VDC-72VDC.

Three configurations are:

  • Model 4165 Desktop Unit, for applications requiring an enclosure. 
  • Model 4165-DIN, for application requiring mounting on a DIN rail.
  • Model 4166 (board only) for embedded applications. The board has front mounting threaded brackets that facilitate rack mounting.
    • Only the Model 4166 board unit has dual DB9 power connectors for convenience is in bused power applications. 
  • Models 4165/4165-DIN/4166 units are factory configurable for USB port powered operation. Other features include user-selectable fiber, polarity, user-selectable asynchronous data format, and Tx, Rx, and Power LED's.
  • Ruggedized for military applications.
