Drawings
Fig. 1 and 2 are schematic structural diagrams of the present invention.
In the figure, the device comprises a water blocking yarn 1, a water blocking yarn 2, an optical fiber 3, a bundle tube 4, a glass yarn 5, a polyethylene sheath 6, a groove frame 7 made of a non-metal reinforcing material, a polyethylene outer sheath 8 and an air-blowing preformed hole.
Detailed Description
As shown in figures 1 and 2, the channel frame type primary-secondary optical cable is characterized in that a water-blocking yarn 1 and a plurality of optical fibers 2 are paid off and extruded by an extruding machine to form a beam tube 3 optical unit, a glass yarn 4 and a polyethylene sheath 5 are sequentially coated outside to form a secondary cable, and then the plurality of secondary cables are placed in a channel frame 6 made of a non-metal reinforcing material. The slot frame 6 is shaped as a cross as shown in fig. 1 and 2, but may be shaped similarly. An air-blowing preformed hole 8 is formed in the groove frame 6, so that an optical fiber bundle or a micro cable can be air-blown as required, and a polyethylene outer sheath 7 is extruded outside. The water-blocking yarn 1 is a high-expansion water-blocking yarn with the linear density of 700D. The optical fiber 2 is a UV curing optical fiber with the thickness of 0.252mm to 0.256mm after being colored. The outer diameter of the beam tube 3 is 1.8-2.0 mm, and the material of the beam tube 3 is polybutylene terephthalate (PBT). The material of the glass yarn 4 is a water-blocking glass yarn with the linear density of 600T. The polyethylene sheath 5 is made of medium density polyethylene, and the wall thickness of the polyethylene sheath is 0.4-0.6 mm. The material of the groove frame 6 made of the nonmetal reinforcing material is a thermal curing molding material after mixing the glass fiber and the epoxy resin, and the middle part of the groove frame is provided with an air-blowing preformed hole 8 which can be used for blowing the micro optical cable or the optical fiber bundle according to the requirement. The polyethylene sheath 7 is made of high-density polyethylene.
The utility model discloses the optical cable can also add miniature optical cable or optical fiber bundle in the condition of laying well to can also carry out the separation operation, it is also very suitable to be used in optic fibre policy of registering one's residence. The optical cable has good electrical performance, excellent environmental adaptability and certain mechanical performance, adopts a full-dry type, is not filled with factice, and has good environmental protection.
