Data transmission between electronic equipment which are physically separated by a distance of typically up to 30,000 feet can be achieved by using Avago Technologies 20mA current loop transmitter and receiver optocouplers. By using these optocouplers, direct control of 20mA current loop and high noise immunity can be achieved.
