Unstable microduct connectors for cable jetting solution


Unstable connections cause microduct to disconnect or shift during installation. This problem results from poor sealing and a loose fit. Technicians report inconsistent cable blowing lengths and frequent interruptions. The following table shows common technical problems with low-quality connectors:

Problem Type

Description

Connection Stability and Reliability

Increased risk of disconnection and inconsistent cable blowing length due to poor sealing and fit of connectors.

Mechanical and Environmental Issues

Mechanical stress leading to damage and environmental susceptibility causing degradation over time.

Installation and Maintenance

Difficult installation processes and challenges in maintenance due to confined spaces and the need for frequent repairs.

Unstable Microduct coupler can lead to the failure of pipeline laying, causing significant losses to the engineering team.

Static Electricity and Contamination


Static electricity and contamination can damage microtube optical cables. Dust, oil and salt on the fingerprint ,it will form a micro-lens on the end face of the optical fiber, which lead to scatter light. A contaminated connector may cause a loss of 0.5 to 1.5 dB, it is even greater than the loss of the entire optical cable operation.


Unclean connectors can weaken signal quality and shorten the lifespan of optical cables. Construction workers must clean the connectors, preventing static electricity accumulation and protecting the system.

Significant Losses from Poor Connectors

Reduced Blowing Efficiency


Poor-quality microconduit connectors can reduce the installation speed of optical cables. The workers noticed that the originally measured length of the optical cable was shorter. This was because the pressure in the pipeline was not enough, preventing the optical cable from reaching its destination. The team must re-plan this process or use additional force to pull out the optical cable, but this may damage the optical cable. The reduction in air-blowing efficiency leads to significant losses of time and resources. The project will take longer to complete, and workers spend more time on each installation.

Tip: Always check connector seals before starting air-blowing. A tight seal helps maintain pressure and improves cable movement.

Installation Failures and Downtime


Poor-quality joints always lead to the failure of micro-pipe laying in pipelines. Workers are also always troubled by Poor-quality joints, which lead to delays and extra work. The following table shows the common causes of installation failure and downtime:

Cause

Description

Difficult Installation

Poorly designed connectors can be hard to install, requiring excessive force and complicating assembly.

Maintenance Challenges

Damaged connectors are hard to access for repairs, increasing downtime and costs due to frequent replacements.

Teams often stop work to fix or replace faulty connectors. Downtime increases project costs and frustrates workers. Significant losses occur when crews must wait for new parts or spend time troubleshooting.

Increased Maintenance Costs


Low-quality connectors are more prone to breakage. The team must regularly inspect and replace these joints. Each inspection and replacement will result in unnecessary cost increases. Frequent malfunctions mean more spare parts and additional labor. Over time, these costs may even lead to negative profits for the project. Reliable connectors reduce maintenance requirements and help prevent significant losses. Companies that use better connectors will significantly reduce their construction costs and also greatly lower the difficulty of construction.

· Regular inspections catch problems early.

· Using durable connectors reduces the need for replacements.

· Well-maintained systems save money and time.

Long-term reliability depends on the connector's ability to handle pressure and harsh environments. For this reason, FCST has been constantly optimizing the production process of micro-tube joints. In the production process, it adopts a full-process control of automated injection molding, fine processing, three-in-one integrated assembly and multi-link inspection, and has achieved high-quality production of joints. The 15J microtube connector developed by FCST is an important representative among them. The reliable performance of the 15J connector has been verified by the following tests.

  •  Impact test: A 15-joule impact test is conducted in accordance with the IEC60794-1-2-11 standard to verify the resistance to external forces.

  •  Acid and alkali chemical resistance test: simulation environment (such as oil, soap, water infiltration) material stability, soak a specific reagent on testing in 5-7 days.

  •  Resistance to stress cracking test: assessment materials without external force will happen crack under the action of natural environment, to ensure long-term reliability.


FCST mainly follow EN 50411-2-8 (2009 edition) standard, and carries on the related test from the following aspects of joint

  •  sealing test: inflatable to 40 kpa, immersion 15 minutes, observe whether the leak or bubbling.

  •  Pressure drop test: pressure maintaining record pressure value after 30 minutes, 60 minutes and then reading, differential pressure shall not exceed 1.5 bar.

  •  Retention test: 40 kpa pressure and 125 n (about 12.5 kg) weight, 60 minutes, less than 2 kpa pressure drop.

  •  Extrusion test: 450 n pressure under 40 kpa pressure for 10 minutes, check whether the deformation or leak.
