Curved fins are respectively provided on every side of the utility model holding part, fin one end is arranged on side, another
End is hanging, and hanging part exists for installation fibre ribbon when processing and filled layer, fin for Loose tube in the top of opening, opening
Opening is sealed when coating holding part, filled layer and fibre ribbon is avoided to enter Loose tube from opening；And fin uses arc wing
The material of piece, fin is silica gel material, and silica gel material is softer, when Loose tube coats holding part, is set on curved fins and side
The lug boss set avoids and generates offset between holding part and Loose tube, improves stability.
The utility model is respectively provided with strengthening core in holding part and insulating layer, increases intensity and the stretch-proof of entire optical fiber
Performance；There are physical isolation and protection between every fibre ribbon, avoids mutually going here and there between fibre ribbon around enhancing fiber-optic signal biography
Defeated stability.The utility model is provided with multilayer proofings structure, the enhancement layers such as Loose tube, water blocking layer, inner sheath, enhancement layer and adopts
With aramid yarn, the structural strength of entire optical fiber is further improved, water blocking layer maintains good waterproof effect, improves optical fiber
Overall performance, extend the service life of optical fiber.The utility model transmission capacity is big, loss is small, electromagnetism interference is strong, the longevity
The advantages that long is ordered, the occasion of the special optic fibres such as communication, fire-fighting, hospital, institute, enterprise is can be widely used for.
