The structure can meet the requirements of stable optical cable structure, small gaps in each element and about 0.5%, wherein the electric units generally adopt single-core double pairs, and for small core numbers, the insufficient number of sleeve elements can be supplemented by filling ropes, so that the cost is increased, and the photoelectric hybrid cable structure with small core numbers needs to be sought. Auxiliary reinforcing pieces or filling ropes are added in gaps at two sides of the optical cable structure adopting the equal-core structure, the filling ropes generally adopt internal PE+external PBT, and the external PBT can stabilize the tensile strength of the filling ropes.
