BOSTON Technology has introduced the Model 272A, RS422 to fibre optic line driver, featuring a data rate of up to 2.5Mbps, full duplex TD and RD and industry standard ST connectors.
The Model 272A provides the capability of performing an interface conversion between full duplex, RS422 signals and their equivalent for fibre optic transmission.
For applications where the transmission medium must be protected from electrical interference, lightning, atmospheric conditions or chemical corrosion fibre optics is the solution.
The Model 272A, RS422 to fibre optic converter handles full duplex data rates to 2.5Mbps. The electrical interface to the RS422 port is fully differential for transmit and receive data and is implemented in an industry standard DB25 connector.
The fibre optic ports are implemented using the industry standard ST connectors. The design has been optimised for 62.5/125 micron fibre cable, however other sizes may be used.
The optical signal wavelength is approximately 830Nm.The optical power budget for the Model 272A is 12dB. In normal applications the distance between a pair of Model 272A's will be at least 2km (6,600 ft).
Power to operate the Model 272A is supplied by a small, wall mounted, 9V ac transformer and line cord. Boston Technology 02 9955 4765.
