The diameter with diameter greater than strengthening core B of core A, is arranged with oversheath outside outer layer cable core, and interior cable core layer and outer cable core layer all include many
The circumferentially uniform cable core of bar, cable core includes outside Loose tube, in Loose tube at least provided with 2 optical fiber.
Further, described optical fiber is that multimode fibre, single-mode fiber or tight tube fiber are a kind of, can be other special light
Fine.
Further, it is provided with tear rope between outer layer cable core overcoat and oversheath, therefore in construction, only need to haul tear
Rope can stripping optical cable it is not necessary to the instrument of specialty, and hand will not be hindered, therefore the utility model has that stripping is convenient, is not required to
Specialist tools, more effective to protecting human body.
Further, strengthening core A is wound with a water blocking yarn.
Further, it is also filled with fine cream in described Loose tube.
Further, described water blocking layer is the bundle yarn that blocks water being wrapped in outside interior cable core layer and strengthening core B.
Further, the material of described strengthening core A and strengthening core B is FRP material, and strengthening core A is round bar shape, strengthens
Core B is high strength glass fiber reinforced plastics bar, and strengthening core B is round bar shape or strip or triangle is shaft-like, and strengthening core B can be it
His suitable geometry.
Further, the material of described oversheath is HDPE high-density polyethylene material or high molecule plastic material.
The beneficial effects of the utility model are as follows：
1st, the utility model structure is simple, optical cable center strengthening core A diameter is reduced, optical cable drawing mechanical performance is not
Foot, is that high strength glass fiber reinforced plastics bar makes up by placing strengthening core B between interior cable core layer and outer cable core layer, full
The mechanical performance of sufficient optical cable, improves density of optic fibre simultaneously, has accomplished the optimization of optical cable, this special enhancing structure optical cable ratio
It is little that common layer-twisted type structure optical cable has an external diameter, and fine density is high, can save conduit resource, have more preferably higher protective
Can, it is suitable to obtain more application in the applied environment in optical cable field or urban pipe network.
2nd, the setting of tear rope, in construction, only need to haul tear rope can stripping optical cable it is not necessary to the work of specialty
Tool, and will not hinder hand, therefore the utility model have that stripping is convenient, be not required to specialist tools, more effective to protecting human body.
