Frequently Asked Questions

Question 35:  WHAT DO I NEED TO USE FIBER OPTIC SYSTEMS?

Answer:  Fiber optic systems are used for transmitting information over long distances.  For example, RS-232 has a distance limitation of 16 ft (5m).  Some projects require the RS-232 data to be sent over long distances, if it is transmitted within 4000 ft (1.2km), then you can probably use an RS-232 data repeater (such as SerialComm's REP-232-3P).  However, if the distance is over 4000 ft (1.2km), then a fiber optic system is recommended.
