Professional Accessories for Fibre Optic Microducting
Accessories for fibre optic microducting are essential components for the construction, connection, and maintenance of fibre optic routes. They include splice protectors, optical end caps, connectors for microtubes, and sealing elements - each responsible for a specific stage of installation and impacting the reliability of the entire system.
If you are looking for certified products for professional fibre optic infrastructure deployments, the guide below will help you choose the right solutions. You will learn about the types of accessories for fibre optic microducting available, what parameters to pay attention to, and why choosing dedicated equipment translates into the durability of the installation and lower operating costs.
Accessories for fibre optic microducting are all elements that support the installation, connection, protection, and servicing of microtubes and fibre optics in a microducting system. The microducting system enables the construction of FTTx networks, where microfibre cables are installed by blowing compressed air or nitrogen into thin tubes called microtubes. An important technical parameter is the diameter of the thin-walled tubes, which typically ranges from 7/3.5 to 14/10 mm in practice. Thin-walled tubes create smooth pathways for microcables, facilitating their installation. Microducting allows for the installation of microtubes in existing telecommunication ducts, as well as for laying them without excavation, significantly reducing investment costs for earthworks.
Using dedicated accessories instead of traditional methods and universal solutions allows for higher tightness (IP68), better resistance to UV radiation and variable temperatures, and full dimensional compatibility with individual microtubes and bundles of microtubes from various manufacturers.
Types of Accessories for Microducting
Each stage of fibre optic installation - from constructing the route underground to completing the connection in the switchboard - requires appropriately selected accessories, and such systems also use blown cables for microtubes, which can be based on a central tube or a multi-tube arrangement. Below we present the most important product categories available in the Senetic offer.
Fibre Optic Splice Protectors
Splice protectors protect the spliced connection of fibre optics from mechanical damage, moisture, and contaminants. The market standard is heat-shrinkable splice protectors equipped with a stainless steel reinforcing rod, which provides rigidity and protection against bending at the splice point.
The manufacturer Extralink, available in the Senetic offer, provides splice protectors in sizes 40-45-60 mm with a reinforcing rod in both individual and bulk packaging. The steel reinforcement of the rod ensures flexibility while maintaining mechanical resistance - this is crucial when installing in the limited space of splice trays.
Optical End Caps for Switchboards
End caps are used to close unused optical connector ports in switchboard panels.
These products protect adapters from dust, dirt, and mechanical damage to contact surfaces. End caps should be made from antistatic materials, resistant to UV radiation and stable over a wide temperature range.
Connectors and Connection Elements
Connectors for microtubes ensure the continuity of the route during cable blowing. Leaky connectors prevent the cable from being blown - maintaining air pressure is essential for the proper execution of this process. Two-part connectors are used to repair damaged sections of microtubes, allowing for quick replacement without the need to replace the entire route.

Frequently Asked Questions
What are accessories for fibre optic microducting?
Accessories for fibre optic microducting are elements that support the installation and protection of microtubes and fibre optics, such as splice protectors, end caps, and connectors. They ensure the tightness and durability of the system at every stage of installation.
What is the difference between internal and external microducting?
Internal microducting requires low-flammability materials, while external must be weather-resistant and meet IP68 tightness standards.
What are connectors for microtubes used for?
Connectors join sections of microtubes, ensuring tightness and continuity of the route during cable blowing.
What pressure should a connector for microtubes of different diameters withstand?
Connectors should withstand a minimum of 12 bar, and higher-class models even 16–20 bar, to ensure safety during blowing.
How are sections of microtubes connected?
Sections are connected using connectors with seals, which are mechanically locked to ensure tightness and durability of the connection.
What are the best splice protectors?
The best are heat-shrinkable splice protectors with a metal reinforcing rod, which mechanically protect the splices and ensure tightness.
What should an end cap be made of?
End caps should be made from antistatic materials resistant to UV and temperature-stable, to protect optical ports from dust and moisture.
