4.Core structure and related machinery 

A.Fiber core (↑)

Equal to copper/aluminum conductor in normal cable , the carrier that realizes the signal transmission 

Fiber core is generated by optical fiber preforming machine and wire drawing tower, these two kinds of equipment need to be used together, and these two sets are of equipment high output, fast speed, high investment cost, technical content demand, so generally only in the mass production will be equipped. Roughly equivalent to the CCR line in the copper/aluminum cable industry . 

In actual production, sometimes it is necessary to use special optical fiber coloring machine to color colorless fiber core.

 

Indoor optical cable, simple optical fiber line, the use of fiber core generally does not need to be colored, the purpose of coloring is to distinguish each fiber in the production and use of optical fiber, but most of indoor optical fiber is adopt tight buffer structure with only one core, so in the production of these two kinds of optical fiber, even if the need to color, the maker will still a direct purchase of colored fiber core as raw material, Regucing the cost of this machine.

Related machinery 

1) Optic fiber preforming&drawing machine

2)Fiber coloring machine

B.Tight buffer (TB)

Note that tight buffer is the name of the structure , not the surface material ,

The extrusion material can be : PVC、LSZH、Hytrel、Nylon、TPU

The structre is 1 fiber core extruded and claded with 1 layer of tight buffer . Generally used in Indoor optic fiber cable  , and the color of the tight buffer is different , so the coloring machine is unnecessary .

C.Loose tube / secondary coating

Loose tube structure is widely used in outdoor optic fiber cable  .

Structure is : 1-12 fiber core/4-24 fiber ribbon + Jelly + loose tube layer

 

The extrusion layer material could be PBT ,modified PP and PE .

Note : the pay-off of this machine could be changed based on the structure : cage type motorized pay-off , with additional S/Z stranding device .

D. Jelly

Its main function is lubrication , water proof and buffer protection .

Jelly is usually non-hygroscopic. It's existing in the sheath of the cable. The type used during telecom installation. They make cables durable

and are ideal for wear resistant use.

Usually will function as a attached device in loose tube extruder , S/Z laying up strander , Outdoor optic fiber cable  cable sheath extruder ：

Relevant optic fiber cable :

 

E. Aramid

Aramid is fiber material to provide tensile strength in cable . It’s tough and Helps tie loose pipes during and after installation .

Used both in outdoor and indoor optic fiber cable  .

There are 3 methods to add the aramid fiber : lateral drag , concentric stranding , S/Z twisting fixed  

Mainly function on sheath extruder with synchronized unit , not a exclusive machine . Can comprehend as the 4 head lateral taping unit and armoring unit on the laying-up machine .

Related machine：

1.Lateral dragging 

2. Concentric stranding 

3. S/Z stranding device

Relevant optic fiber cable :

F. Steel wire , Non-metallic reinforcement member - FRP

Like ordinary cables, the purpose of steel wire is to provide structural strength.

There is 2 method to add this structure , 1 is to lateral drag into the sheath , another is to function as the core in the concentric stranding structure optic fiber cable  

Widely used in FTTH and outdoor optic fiber cable  .

Compared with the same structure reinforced structure of steel wire, it has a better high strength/weight ratio, so it is more suitable for twisting, and because of the excellent anticorrosion, so it is more suitable for frequent rain areas .

G. Steel tape armoring

Steel tape armor in optic fiber cable  generally adopts the form of laser welding after towing (longitudinal wrapping), and then corrugating .
Of course, according to the demand, can also be done in the form of non-rolling.

 

Related machinery :

This process is not normally done in a separate machine, but is integrated into the outer cable sheath extrusion line . 

Device order in the red highlighted area : (right to left) steel/Aluminum tape pay-off , tape tip welder , tape storage device , metal corrugating device , tape lateral foaming device .

Relevant optic fiber cable : 

 

H.Taping - waterproof taping / Aluminum PE

Because optical fibers transmit optical signals at work, the bands in the fiber don't need to act as a signal insulator, as traditional signal wires do.
The main function of the wrapping is to fix the stranded (S/Z stranded technology leads to the stranded body is not tight), protection and waterproof.
The way the tape is wrapped is different at different locations

I. Sheath

Personally I think the sheath line is the most complicated machine line in optic fiber cable  manufacturing Because many structures and processes of optical fiber will be added to the final sheathing extruder in the form of small structures.

To be simple , it means the structures mentioned above will be added into the sheath line before the main extruder - aramid yarn , steel wire , FRP , steel tape armoring , Jelly ,water

block taping . Also the following water trough , guide wheel , storage rack , traction wheel , take-up unit will be slightly different than normal extruder .

Material for indoor optic fiber cable  sheath ：PVC , LSZH , HDPE

Material for outdoor optic fiber cable  sheath ：HDPE , LSZH

Material for FTTH : HDPE
