Option Board F: Fibre Optic Serial Board
The fibre optic serial option board provides a serial
interface via a fibre optic cable. A fibre optic port is
treated the same way as a standard serial port except a
fibre optic cable is used for the communications
medium. A fibre optic link offers excellent electrical
isolation and a high data rate. Two fibre optic cables are
required for each fibre optic port.
