1. A fluid cable transmission system comprising:
a first cylinder comprising:
a first cylinder housing comprising a first opening;
a first piston slidably mounted within the first cylinder housing; and
a first seal member disposed within the first cylinder housing, the first seal member and the first piston dividing the first cylinder housing into a first chamber having the first opening and a second chamber;
a second cylinder comprising:
a second cylinder housing comprising a second opening;
a second piston slidably mounted within the second cylinder housing; and
a second seal member disposed within the second cylinder housing, the second seal member and the second piston dividing the second cylinder housing into a third chamber having the second opening and a fourth chamber;
a tubing assembly connecting the first opening and the second opening thereby placing the first and third chambers in fluid communication; and
a cable connecting the first and second pistons through the tubing assembly;
wherein the first and second seal members prevent fluid in the first and third chambers from entering the second and fourth chambers respectively.
