Electro Standards Laboratories High Speed Rugged ST Fiber-to-USB Interface Converter Model 4166

The Model 4166 is a high speed ruggedized Fiber to USB interface converter board from Electro Standards Laboratories. With its integrated rate buffering, the Model 4166 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 4166 Fiber to USB converter board 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 family of media converters. 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. It is also factory configurable for USB port powered operation. 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. For applications that require an enclosure, it is also available in a desk top package, Model 4165, Catalog No. 304165 or with DIN rail mounting hardware, Model 4165-DIN, Catalog No. 304165-DIN. These Fiber Converters are ruggedized for commercial and military applications.
