Submarine Cable Layer :-
1. The first layer is composed of polyethylene of a chemical water-resistant.
2. The second layer is a plastic material accurate name Mylar.
3. The third layer is composed of steel wire monolith.
4. The fourth layer is a barrier Aluminum Waterproof.
5. Fifth layer consisting of the material Polycarbonate is a special shock-resistant chemical and degree of extreme heat.
6. Sixth layer is aluminum Hijaz extra.
7. Seventh layer is Petroleum jelly.
8. Eight layer class consisting of fiber optic.
Difference between submarine cable vs satellite :-
