271F/ST RS-232 Fiber Optic Auto Powered Line Driver - High-Speed Data Transmission for Industrial Automation & Networking Equipment

The Model 271F/ST provides feature packed performance and reliability for data transmission over glass fiber. Fiber optic transmission offers the benefits of wide bandwidth, immunity from EMI/RFI interference, operation in harsh/hostile environments and secure data transmission. The Model 271F/ST Auto Powered Fiber Optic Line Driver provides full duplex, asynchronous communications over two fibers. Fiber cable length can be up to 2 kilometers with data rates as high as 56 KBPS. The Model 271F/ST has been optimized for 62/125 fiber cables. Other sizes can also be used. The power budget for the 271F/ST with 62/125 cable is 12dB. The operating power for the Model 271F/ST is derived from the transmit data line. The Model 271F/ST is equipped with a DTE/DCE switch that reverses pins 2 and 3 of the RS-232 connector. The RS-232 port can be implemented as a male or female DB25 connector. The fiber cable port connectors are industry standard ST types.
