The Patton Model 1110A miniature RS-232 fiber optic modem packs all the advantages of fiber into a compact self-powered package. Communicating full or half duplex over two fibers, the Model 1110A supports data rates to 19.2 Kbps and distances up to 5 miles (8 km).

  • Optical fiber carries several advantages over twisted pair copper for data communications:

  • In building-to-building applications, copper wire requires DC isolation to avoid ground looping. Fiber, on the other hand, does not have DC continuity. Fiber is therefore not subject to ground looping.

  • If a copper link passes through a field of energy created by a lightning strike, this transient energy will be conducted to the hardware at either end. But a fiber link will not pick up this harmful radiated energy-it is immune to transients.

Being a fiber optic modem, the Model 1110A has all of these advantages.

  • Asynchronous, RS-232 Operation
  • Full or Half Duplex
  • Data Rates up to 19.2 Kbps
  • Range up to 5 Miles (8km)
