Fiber cable blowing technology is a popular optical cable laying technology. The high-pressure and high-speed airflow generated by the air compressor and the microduct conduit or air blowing fiber are sent into the pre-layed silicone tube through cable jetting machine.

Fiber cable blowing is a safe and effective optical cable laying method. During the cable laying process of the cable blowing machine, the traction force of the dragger, the blowing force of the compressed air and the thrust of the conveyor belt act on the optical cable at the same time.

The biggest difficulty in traditional ODN network construction is that the connection between each ODN node equipment and optical cable requires complex optical cable stripping, fixing and splicing operations, which is time-consuming and labor-intensive.

AIR BLOW FIBER (ABF) SYSTEMAir Blow Fiber Systems refers to laying special blown fiber microducts and related accessories in advance before comprehensively laying optical cables. When the optical fiber needs to be installed, the optical fiber is blown into the microduct by the fiber blowing machine.

Tube Distribution Closure (TDC) is a device used in telecommunications and networking applications to manage and distribute fiber optic cables. It is designed to house and organize multiple fiber optic cables and provide a secure and reliable connection between them. Y-Type Tube Distribution Closure are widely used in microduct systems, this article is about how to install the indoor Y-Type micro duct branch closure.

1.Outer protection tube blockeda. Clean the outer protective tube: blow sponge balls into the HDPE duct to remove accumulated water and dust that block along the air blown fiber duct; survey the location of obstacles in the outer protective tube and remove them. 2.HDPE fiber optic conduit can't blow.

As we all know, the selection of raw materials has a great impact on the characteristics, load-bearing level and service life of the telecom fiber vaults. So what are the common raw materials for draw pit chamber? Generally speaking, there are three materials: PE, BMC, and SMC material.

China Unicom cable installation team got a little problem when install fiber cable inside telecom pipe, here is the situation as below:Situation 1: There is a silicon core tube 40/33mm underground.Situation 2: There is a GYTA-48cores fiber cable already in the silicon pipe.

1.PREPARE THE DUCT SYSTEM ACCORDINGLY2.SELECT THE SUITABLE CABLE DIAMETER FOR THE EXISTING DUCT SYSTEMThe ratio of the outer diameter of the cableto the inner diameter of the duct should be close to 60%. With this value, the greatest blowing distance is achieved. 3.CHOOSE THE RIGHT COMPRESSOR.
