Telecom, fibre optic and PTT manhole products are factory-produced precast concrete and reinforced concrete structures used to provide access to the cable systems in urban communications infrastructure. Depending on the size of the product, these manhole structures provide either maintenance access from above or a working space suitable for personnel entry, so that maintenance, repair, jointing and new line work on communications networks can be carried out safely and in a controlled manner.
In these products, manufactured by the precast production method, control of the moulds, concrete, curing process and dimensions is ensured under factory conditions. The product group consists of manhole types that suit different communications systems, in line with the project and the specifications of the relevant authority.
Unlike inspection manholes, property connection chambers and storm water chambers, telecom, fibre optic and PTT manholes are used not to carry fluids but to access and organise communications cables.
Typical Areas of Use
- Access and jointing points of telecom and data lines
- Communications backbone and distribution lines
- PTT and similar communications cable routes
- Communications infrastructure access points on urban avenues, streets and boulevards
Key Advantages
- Controlled production: Body dimensions, cable entry openings and frame seating surface details are produced in a standard and repeatable manner in the factory environment.
- Maintenance access: Depending on the product type, offers space suitable for work from above or for personnel entry; working conditions are assessed within the scope of the application.
- Fast installation: Delivered to site in finished form, without requiring in-situ formwork or concrete casting; shortens installation time.
- System compatibility: Offers solutions that meet the requirements of different communications infrastructures, such as telecom operator applications, fibre optic lines and PTT routes.
Subcategories
Telecom Products
These are manhole types selected taking into account the relevant communications operator's specification applicable to the project. Dimensions, internal volume and connection details are checked against the product documentation.
Fibre Optic Manhole Products
These are manhole types used at the jointing, distribution and routing points of cables in communications infrastructure. These manholes are produced in standard dimensions and details so as to have an internal volume and geometry suited to cable organisation. Fibre optic manhole products use a steel frame mounted on the base unit and a high-strength cover, based on reactive powder concrete (RPC) and compatible with this frame.
PTT Manhole Products
These are manhole solutions used for access along communications cable routes. Sizes and details are selected from standard size lists and applied according to the area of application and the project requirements.
