[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is widely used Applied in the communication industry, when constructing in office buildings, computer rooms, etc., since the existing optical cables have no connecting parts, in the vertical laying or horizontal laying construction, each floor needs to be re-wired, which is cumbersome to operate and repeat construction. Inefficient and wasteful of material and labor costs

Embodiment 1
[0021] see figure 1 , a ladder-shaped pre-terminated optical cable and a production method thereof, the optical cable is sequentially provided with a central tensile body 1, an optical fiber 2, a microtube 3, an aramid fiber 4 and a flame-retardant sheath 5 from the inside to the outside, and the optical cable is also provided with Including a connector, the connector includes a connection body 6, a connection head 7 and a connection tail 8, and the connection body 6 is arranged in the middle of the connection head 7 and the connection tail 8; the height of the optical cable laying floor is N meters, where N is greater than 2, the position of the connector is set at N meters away from the head end of the optical cable, the second sub-cable is set at 2*N, the third sub-cable is set at 3*N, and the distance between the joints of each two sub-cables is Not less than N meters, and so on. When N is 4 meters, the height of the optical cable laying floor is 4 meters, the position of...
Embodiment 2
[0024] see figure 2 , image 3 , a method for manufacturing a ladder-type branch preformed end optical cable, the method is as follows:
[0025] 1) Unwinding, making microtubes, placing optical fibers of different colors on the pay-off rack; extruding, passing through the extruder, adding a layer of sheath to the optical fiber, and the appearance is round; cooling, passing through the water tank, and removing the sheath Cooling; blowing, passing through the blower to dry the surface of the optical cable without water marks; measuring diameter; printing, and then the inkjet printer sprays codes on the microtubes, which is easy to distinguish; traction, the traction machine gives power to the entire production line, Then directly on the market;
[0026] 2) Place the produced microtubes on the pay-off rack, and install an automatic cutting device in front of each pay-off rack. The length of the micro-tubes in this stepped branch optical cable is different, depending on the cus...

Abstract
The invention relates to a step-type branched preformed end optical cable and a production method thereof. The step-type branched preformed end optical cable is characterized by sequentially comprising a center anti-tensile body, optical fibers, micro tubes, aramid fiber yarns and a flame-retardant jacket from inside to outside; the optical cable also comprises a connector; the connector comprises a connector body, a connection head part and a connection tail part; the body is arranged between the connection head part and the connection tail part; the height of a floor on which the optical cables are laid is N meters, wherein N is greater than 2; the connection head part is arranged at a position N meters to the head end of the optical cable; a second sub cable is arranged at a position 2*N meters to the head end of the optical cable; a third sub cable is arranged at a position 3*N meters to the head end of the optical cable; the interval between draw-out joints of each two sub cables is not less than N meters; the rest sub cables are arranged in the same manner. Relative to the prior art, the step-type branched preformed end optical cable and the production method thereof have the following advantages that 1, the integral structural design is ingenious and the cost is relatively low; 2, the technical scheme avoids repeated construction and materials and labor cost are reduced; 3, according to the technical scheme, the micro tubes in the optical cable have different lengths and are automatically cut by equipment and the step-type branched preformed end optical cable is very convenient.
Description
technical field [0001] The invention relates to an optical cable, in particular to a ladder type branched preformed end optical cable and a production method thereof, belonging to the technical field of communication. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is widely used Applied in the communication industry, when constructing in office buildings, computer rooms, etc., since the existing optical cables have no connecting parts, in the vertical laying or horizontal laying construction, each floor needs to be re-wired, which is cumbersome to operate and repeat construction. Inefficient, and a waste of material and labor costs. Therefore, there is an urgent need for a new technical solution to solve the above technical pr...
