How To Solve Microduct Blockage In ABF System?

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. Silicone tube protection can greatly reduce the friction coefficient between optical cables and conduits, greatly increase the length of a single laying. However, encountering blockages during this process is a common challenge that needs to be handled promptly and efficiently. The following will introduce how to deal with blockage when laying optical cables in cable jetting solution.

The first step when encountering air blown fiber cable blockage is to immediately stop the ongoing air blowing operation. Continuing this process may exacerbate the problem and may cause damage to the fiber optic cable or related equipment. Next, it is crucial to locate exactly where the cable blockage is.

A.Check air pressure and air flow

Ensure that the air pressure and air flow meet sufficient requirements to ensure sufficient pushing force to push the fiber optic cable through the conduit. Use a barometer and air flow meter to ensure the stability and proper air pressure and air flow.

B.Check bundled microduct status

Check the inside of the duct for any bends, pinches, or other irregularities that could cause a blockage. Use a camera or other pipe inspection tool to inspect the inside of your pipes to determine if there are any obstructions or damage.

C. Check the status of the optical cable

Check whether there are any abnormalities in the air blown fiber cable during the laying process, such as breaks, knots, twists, etc. Check the connection points and fixing points of the fiber optic cable to make sure there are no loose or detached parts.

D.Use probing tools

If the above steps cannot determine the location of the blockage, you can use professional detection tools to help locate the blockage point. Infrared detectors can be used to detect hot spots within pipes, which may indicate obstructions or damaged areas. Sound detectors can be used to listen for changes in sound within the pipe, which may indicate the location of a blockage or point of damage.

Once the location of the blockage is determined, appropriate measures can be taken to resolve the problem. To clear obstructions in the pipeline, you can use fiber blower machine or other tools to remove foreign matter in the blown fiber duct. Repairing optical cable faults can repair optical cable breaks or other damage to ensure the integrity and normal function of the optical cable. In severe cases of blockage, it may be necessary to partially disassemble the cable for thorough cleaning. When performing removal operations, be sure to pay attention to safety to avoid secondary damage to pipes and optical cables. After the blockage is removed, the integrity and performance of the fiber optic cable must be evaluated. Check whether the optical cable is loose.

Preventing clogging is the key to smooth air-blowing fiber optic cable laying. Fiber optic cables should be cleaned and maintained regularly to prevent dust and debris from accumulating and causing blockages. Use appropriate fiber blowing equipment and follow correct operating procedures during the blowing process.
