FAST FIBRE OPTIC NETWORK CONSTRUCTION

High-speed fibre optic networks - Laying fibre optic cables and fibre optic connections without trenches

A high-performance fibre optic network is the backbone of digitalisation. However, broadband expansion is not progressing as quickly as necessary in many places. This is due to the high costs for installing thefibre optic cables, but also time-consuming civil engineering procedures. Cost and time can be reduced if the trenchless technology method is used.
 
Using our innovative NODIG systems for the underground installation of protection pipes and cable routing, you can quickly and cost-efficiently expand your fibre optic network directly to the premises (FTTX)  or into the cellar without any follow-up costs.

Trenchless fibre optic cabling: FTTX without surface damages

No deep slits in the asphalt for cable routing, low restoration costs and no impairment of the affected traffic areas - these are the advantages of the NODIG technology. Using trenchless construction methods, fibre optic cable laying is safe, cost-efficient and fast, be it under or along roads (FTTC) directly into the house (FFTH) or into the cellar (FFTB). Adequate installation depths for fibre optic connections guarantee security of supply. 
 
With NODIG technology fibre optic networks are quickly built and easily expanded at every stage: from the main distribution board via the sub-distribution board and the house transfer point to the actual network connection (NT).

The advantages of fibre optic cabling with NODIG technology AT A GLANCE

  • Fast underground installation of protection pipes and fibre optic wires along roads (FTTC) and under traffic routes with short or long pipes made of all standard materials.
  • Installation of fibre optic cables through existing sewers is also possible.
  • Trenchless technologies are suitable in rural areas and urban areas.
  • Construction of single or serial fibre optic house connections from the distributor to the building (FTTH) and directly to the basement (FTTB) or vice versa.
  • Proven techniques and tailor-made accessories guarantee maximum speed and profitability.
  • Fast and without surface damage: Minimally invasive underground laying of protection pipes and fibre optic wires along roads (FTTC) and under traffic routes with short or long pipes made of all common materials.
  • Laying the fibre optic cables through existing sewers is also possible, thus minimising interference with residents and traffic.
  • Use in rural areas and in urban space: from fibre optic network expansion in the countryside to distribution and house connections in the city centre.
  • All fibre optic connection variants are possible (FTTX): Establishment of individual or serial fibre optic house connections from the distributor to the building (FTTH) and directly into the cellar (FTTB) or in each case in the opposite direction.
  • Reliable technology guarantees the cost efficiency of your fibre optic network project: Tried and tested procedures and perfectly matched accessories guarantee maximum speed and cost-effectiveness.

Brief fibre optic cabling glossary 

  • FTTX ("Fibre to the X")
    A generic term for broadband network architecture and fibre access technologies (FTTH, FTTB and FTTC). 
  • FFTH ("Fibre to the Home")
    The fibre optic cables are laid directly into the user's house/flat.
  • FFTB ("Fibre to the Building")
    The connection of the fibre optic extension reaches right into the cellar of the user.
  • FFTC ("Fibre the the Curb")
    Better known as VDSL. The fibre optic cables run to the distributor at the curb. From there, the signal is transferred via the copper lines of the telephone network.
  • FTTG ("Fibre to the Ground")
    Transfer of the fibre optic cable by means of a special 'G-Box' as a fixed transfer point between the property and the pavement.
  • OPGW (“Optical ground wire”)
    Dual functioning cable combining the functions of grounding and communications.
  • VDSL ("Very High Speed Digital Subscriber Line")
    Improved DSL network with higher transmission rates, identical to 'Fibre to the Curb'.
