Model 4165 High Speed Ruggedized
Fiber-to-USB Interface Converter, Desktop Configuration.

The Model 4165 is a high speed ruggedized Fiber-to-USB interface converter from Electro Standards Laboratories. With its integrated rate buffering, the Model 4165 converts USB 2.0 compliant data from a standard PC to a serial asynchronous data interface over fiber with a user selectable baud rate of up to 3 Mbps.

The Model 4165 is ideal for applications involving PC communications that require high speed, secure communications, and optical isolation. Typical applications include constructing an optically isolated point-to-point communications link between the USB ports of two PC's, or an optically isolated high speed communications link between a PC and a serial data network subjected to a high EMI environment that might corrupt communications over a copper interface.

Designed to operate from -40°C to +85°C, it is a member of Electro Standards Laboratories' rugged community media converter family. The unit features ESD protection circuitry on the USB I/O connector. The unit's power input is protected from transients and features 3kVDC isolation to prevent system ground loops. It can be powered from a wide input range of 10VDC-36VDC, with models also available for other voltage ranges such as 4.5VDC-9VDC and 19VDC-72VDC.

Other features include user selectable fiber polarity, user selectable asynchronous data format, dual DB9 power connectors (board only) for convenience in bused power applications, Tx, Rx, and Power indicator LEDs. The converter is available as a board only with front mounting threaded brackets for rack mounting in embedded applications. It is also available in a desk top package with DIN rail mounting hardware for applications that require an enclosure.
