Fiber-optic communication came about in the 1970s due to advances in both optical cable and compact lasers capable of sending light over long distances through the optical cables. What benefit does fiber-optic communication provide over metallic wires?
a. Fiber-optic cables are capable of sending information over a very long distance.b. Fiber-optic cables have very high bandwidth with no electrical crosstalk or electromagnetic interferencec. Fiber-optic cables are widely available directly to most homes and do not need to worry about “last mile” problems.d. Fiber-optic cable is very durable and easily repaired.
