Fiber Cable Blowing Machine – Everything You Must Know

Fiber Cable Blowing Machine – Everything You Must Know


Cable blowing is a commonly used technique for telecommunication network establishment. There are fiber cable blowing machines in the market that help in completing the task. What does it do? The machines help in fitting the fiber optics cable inside the subducts or micro ducts. . The fitting requires a medium to ensure zero gaps, for which you require using compressed air or water. There are different cable blowing machines available in the market based on the cable and material of the duct in use. 


About the design


A fiber cable blowing machine has more than one component. Each part of the machine is essential for the complete functioning cable blower machine. The different parts are – head, belt feeder, base plate, meter counter etc. The head of the machine is responsible for the secured fitting of the cable and duct. The cable which needs to be inserted or blown into the duct passes through the head. The belt feeder moves the cable and the base plate acts as a mounting medium for the process. 


How does it work?


If there is a gap between a cable and a subduct or micro duct, there will be problems in the whole setup. Thus, accurate setting through cable blow is crucial. The fiber cables get fitted with the help of the medium and machine in concern. The machine uses compressed air or water and shoots the optical fiber. The fiber travels through a long distance with the help of the pressure of the compressed medium. 

The essential components in a fiber cable blowing machine make it possible for the cable to fit into the subduct or micro duct precisely. Maintaining every part of the cable blower is essential for ensuring the long life of the machine and optimal functioning. System cables, inlets for connection and the monitoring unit, all have separate functioning utilities. The meter counter in the blower machine helps determine the correct velocity and practical speed of the blown cable. 


Different blowing machines


You can find multiple variants in the fiber cable blowing machines. The types depend on the size of the ducts and the medium in use. The cable blowing technique can also be divided into two types, depending on their power units. 


  • Pneumatic: These are light weighing cable blower machines. The operating modes are simple compared to the rest. The pneumatically powered engine uses compressed air for blowing the cables through a long distance. 
  • Hydraulic: In hydraulic blowing machines, there are two primary components – cable feeding point and hydraulic power-point. These are among the most-used blower machines for cable blowing in practical applications. 


Know the application


Fitting the cable into the micro duct is the primary application of the fiber blowing machines. High-quality fiber cable blowers are an asset for every technician associated with establishing a telecommunication network with long-distance cables. It reduces time and ensures precise cable blowing through the long networking lines. The blowing technique is better than pulling, for which these machines are gaining more importance in practical applications. Distant networks and telecommunication fields utilize these to reduce frictions. 


Why is it crucial for long-distance networks?


You can find the utility of these cable blowers in all telecommunication fields. But, the use of the machine is particularly essential in long-distance sites. Why? Firstly, it reduces friction efficiently. Secondly, the ability of these blowing machines to fit the cables into subducts or micro ducts through the bending and curves make them an indispensable part. It is easy to maintain the network route with the cable blowing machine and, thus, it has high utility worth in practical applications. 


  • For better protection: With the cable blowing machine, you can successfully avoid the worries of unsafe fittings of cable and ducts. The different parts of the machine do not allow the medium to enter into the fitting area. Thus, it is possible to establish a secured connection with the fiber cable blowing device. It is apt for the new-age optical fiber cables and subducts or micro ducts of varied sizes. 
  • For better performance: The blowing technique has eased the practical challenges encountered in the curvy telecommunication routes. It ensures a frictionless and accurate cable fitting. Thus, the performance of the machine gets better with reduced interruptions. The flexibility allows you to prevent signal losses in the bending areas for the perfect fitting. 


Find a reliable supplier and manufacturer.


If you need to order a fiber cable blowing machine for establishing a secured telecommunication network or for lab testing, find a reliable source to purchase. These machines, as discussed before, have different variants. Hence, each variant comes with distinct certifications and industrial standards for ensuring optimal output in practical applications.

Getting the machine from a reliable supplier help in eliminating the worries of functioning errors. Order the best cable blowing machine at a justified price and fit the requirements within the estimated budget. Evaluate the machine parts and features thoroughly and get the best outcome. 



Duct Integrity Testing :

The Duct needs to be tested before starting the fiber cable blowing process to ensure that the duct is suitable for Fiber Cable Blowing. The steps involved in the Duct Integrity testing popularly known as DIT are listed below.

1.       Continuity Test : For checking the continuity of the duct.

2.       Mandrel or Shuttle Test : For checking the blockages inside the duct.

3.       Sponge Test : This is not really a test but used for cleaning the duct from inside.

4.       Pressure Test : To check the leakage in the duct.
