Classification of uses of air-blown micro-optical cables

Presumably many people have a certain understanding of optical cables. The types and types of optical cables are closely related to their uses. So what are the uses and classifications of air-blown micro-optical cables? The application field of optical communication has been gradually expanded. Optical communication has become the most popular network communication method. Air-blown micro-optical cables will also have technologies that need to be adapted to different scenarios. The microtube unit is composed of HDPE material and silicon core layer on the inner wall. At present, the outer diameter of microtubes in the world is generally from 3mm to 16mm. The number of fiber cores that can be accommodated in a microtube ranges from 1 core to 288 cores or even higher.

Types of Microtubules

Micropipes are an important part of the air blowing system. Just like urban roads, the micropipes must be laid to the destination before the microcables are laid, and they are required to be laid in place at one time. Because the micropipes laid for the first time and the micropipes laid for the second time may be entangled, in a protective pipe (protective pipe: the protective pipe refers to the pipe that protects the micropipe bundle, and this pipe can be used for air blowing Silicon core pipes, PVC pipes for traction, sub-pipes for local telephone pipes, grid pipes and other pipes for laying optical cables) cannot be laid in batches. The following 2 kinds:

cluster tube

The cluster tube is a bit like the honeycomb tube commonly used in our local telephone pipes. It is composed of a microtube bundle and an outer sheath composed of loose microtube units. There is no adhesion between the sheaths, and there can be relative displacement. The advantage of the cluster tube is that the density of the tube is high, which can accommodate the most microtubes in the effective space. The disadvantage is that the flexibility is poor, the opening and sectioning of the pipeline is inconvenient (referring to the thick-walled outer sheath), the inner microtubule is difficult to divide, and the impact resistance is also poor, because the microtubule unit is tightly protected by the protection tube. Wrapped together, the deformation of the protective tube can directly cause the deformation of the microtubule.

Air Blown Micro Cable

At present, according to the different uses of the project, the cluster pipe is divided into direct buried type, pipeline type, bundled type, flat type, overhead type, flame retardant type, anti-termite type and armored type. Distinguished from the shape, the cluster tube has round, polygonal, square and flat type. The round bundles are mostly bundled with a thick-walled outer sheath, the polygonal bundles are generally bundled with a thin-walled outer sheath, and the square and flat bundles have thick-walled and thin-walled outer sheaths.

Directly buried cluster tube: The directly buried cluster tube is composed of a thick-walled outer sheath plus a standard wall thickness microtube unit or a thin-walled outer sheath and a thick-walled microtube unit. Due to the difficulty of cutting and improving the flexibility of the bundled tube, the bundled tube of the thick-walled outer sheath began to transform into the bundled tube of the thin-walled outer sheath. The directly buried bundled pipe can be directly purchased into the groove of the pipeline.

Pipe-type cluster pipe: The pipeline-type cluster pipe is composed of a thin-walled outer sheath and a micro-pipe unit of standard wall thickness, which is suitable for laying in buildings and air blowing or traction in pipelines with protective pipes.

Bundled microtube bundles: The bundled bundles use thinner nylon ropes to combine the microtubule units by bundling, which can be used for traction, air blowing and direct burial laying. The laying method depends on the microtubules. The wall thickness of the unit and the material of the protective tube. This shape of the cluster tube can maximize the use of the space of the protection tube and the channel, and the combination is very flexible. In a 40/33mm protective tube, 4 groups of 6 microtube units of 4/3mm can be blown in each group.

Flat cluster tube: The flat cluster tube is mostly used for standard channels excavated by machinery in urban areas. The width of this channel is very narrow, so the flat cluster tube is very suitable for this channel, and at the same time at the level of the line Turning points are no problem either. However, for a line with high and low fluctuations, it is more difficult to lay the bundled tube at the point of direction change. To solve this problem, a flat cluster tube that can be rolled into a circle has been developed.

Overhead type cluster tube: The overhead type cluster tube is a cluster tube with a figure 8 structure. The manufacturer combines the cluster tube and the reinforcement unit of the overhead support, which is suitable for access and drop-off.

Flame-retardant cluster tube: The flame-retardant cluster tube is mainly composed of low-halogen smokeless micro-pipe units and outer sheaths, and is used for direct laying in buildings.

Anti-termite cluster pipe: The outer sheath of the anti-termite cluster is made of a material that enhances the mechanical strength of the pipe and provides chemical protection to prevent termite damage.

Armored cluster tube: The armored cluster tube uses a layer of corrugated steel tape in the outer sheath to protect the microtube bundle, which can effectively prevent animals from biting.

Thick-walled outer sheath and standard-walled micro-tube unit combined direct-buried cluster tube Thin-walled outer sheath and thick-walled micro-tube unit Combination of direct-buried cluster tube with very thin outer sheath and standard wall The tube-type cluster tube composed of thick microtubule units has no outer sheath, and all standard wall thickness microtubule units are bundled with thin ropes

The above are the detailed knowledge points about the classification of the use of air-blown micro-optical cables. I hope we can increase our understanding of optical cables. ZR Cable is well received at home and abroad, with high cost performance. The equipment produced by ZR Cable optical fiber manufacturers is now not only used in communication, but also in temperature sensing test, fire warning and so on. Many mines, oil fields, high-speed railways, subways, buildings, forest fire prevention, etc. have used armored optical cables made by ZR Cable for temperature sensing test fire warning.
