Very bad idea

Sorry, bad math

Why run a 40,000km cable when you could just run a 3 foot cable
the opposite direction?
If you'll use 3 feet cable you'll be 20'000km from destination. You get
40'000km when two points are antipodes: it does not matter which way you'll
go it's 20'000km one way and then 20'000km another way - direction is
irrelevant. The only way to reduce distance is to burrow a hole and the
depeest hole known to a man (less then 15km) does not shrink the distance all

The device capable of burrowing straigh through Earth? I know few
guys who'll pay BIG BUCKS for such thing - where are selleing it?
And if you are not selling then the only way to go to the antipode is
along the Earth surface - so yes, 40'000km (give or take) is shortest path

The distance between antipodes is half that - 20000km ALONG THE EARTH SURFACE. It would be ~12000km thru the center of the Earth.
