Further, a plurality of optical fiber cable includes optical fiber cable core and the Loose tube being arranged on outside optical fiber cable core.

Further, it is cross-linking radiation polyolefine material that thickness is 0.8 ~ 1.6mm that the material of the inner insulating layer, which is, Or cross-linking radiation EP rubbers material.

Further, the flame retardant coating includes the copper mesh, expanded granular layer, the mica layer that set gradually from inside to outside, institute Mica layer thickness is stated as 0.25-0.63mm, the filament diameter of the copper mesh is 0.26-0.96mm.

Further, shielded layer A includes the copper foil layer that thickness is 1.1um, and it is 10um ~ 15um's that thickness is coated on copper foil layer Aluminium foil layer.

Further, shielded layer A is the spiral wound shielded layer that material is tinned copper wire.

Further, the strengthening core of copper-coated aluminium composite material by being made.

The beneficial effects of the utility model are as follows：

1st, the utility model is simple in structure, and shield effectiveness is good, and damp-proof and fireproof performance is good, and overall structure is uncomplicated, quality The advantages of lighter, is conducive to use suitable for aviation.

2nd, shielded layer A includes the copper foil layer that thickness is 1.1um, and the aluminium foil layer that thickness is 10um ~ 15um is coated on copper foil layer, This structure of shielded layer can ensure shielded layer under identical thickness, and layers of copper structure is used than traditional list using this structure Copper material is more saved, has saved cost, on the other hand, aluminium foil quality is lighter, and so as to also reduce the weight of shielded layer, which keeps away The problem of having exempted to occur exoperidium bulge when working out cable shield using tinsel or pierce through core.
