(9) Coaxial/optical converter, repeater
This device converts electrical signals on a coaxial cable (10BASE5/10BASE2) into optical signals,
and from optical signals to electrical signals. A FOIRL (Fiber Optic Inter Repeater Link) is used to
connect repeaters in a 10BASE-FL network. The device is used to prevent noise and extend the
length of a cable.
