How fiber optics are used in instrumentation?

Answer 1

Data communications typically use electrical pulses that are of specific characteristics to send ASCII or other data protocols.

An electrical signal requires two wires, is susceptible to static interference and in some cases can be compromised by running a wire nearby.

Some applications use fiber optics to send light pulses that are of specific characteristics to send ASCII or other data protocols.

Using fiber optics, light pulses are sent through a thin, glass fiber conduit. Lightening and other electrical sources do not produce static and the signal cannot be compromised by running a wire nearby.
