    Planning and technical support

    Planning and technical support

    We ensure the pre-planning and design work, especially for private network customers. A part of this work is an elaboration of the optimal solution, including price quotations.

    Design work always includes Land-use permission and as built inspection.

  • Trenching and optical cables placement

    Trenching and optical cable placement

    Trenching and optical cable placement
    • During the new optical route construction we provide trenching and HDPE subduct placement for optical cables, HDPE subduct pulling into existing underground facilities as well as self supported aerial optical cables and ducts.
    • Further we provide river and creek crossings and final asphalt surface arrangement.
    • When installation is completed, we obtain the acceptance documents from all landowners.
  • HDPE duct freeway inspection and pressure testing

    HDPE ducts freeway inspection and pressure testing

    HDPE duct freeway inspection and pressure testing
    • Prior to optical cable installation itself, freeway and pressure inspection is essential.
    • Freeway inspection can be done by an electronic transmitter.
    • The electronic transmitter is blown through the HDPE using an airflow.
    • Trouble points that can occur during placement or backfilling are located and repaired as necessary.
  • Cartographic positioning of routes and make-out of as built cable book
  • Civil works and building and structural modifications
  • Optical cable splicing

    Optical cable splicing

    Optical cable splicing
    • The splice itself is protected by mechanical 40 or 60mm tube splice protectors.
    • In rural areas, underground chambers are used for the placement and protection of optical closures.
    • Fibers can be spliced mechanically or with fusion machines.
    • Fusion machines automatically align core to core in "X" and "Y" axes, makes splices and provide loss estimation.
    • These are marked with underground 3M markers for easier future localization.
    • Fibers can be terminated with pre-fabricated pigtails or directly with various optical connectors.
  • Otical cable blowing into HDPE ducts
  • Blowing of second optical cable into already occupied HDPE ducts

    Blowing of the second optical cable

    Blowing of the second optical cable
    • For the increasing demand of the number of fibers we offer an effective use of existing HDPE duct, already occupied by one optical cable. For such a network configuration, where an additional trenching and duct placement is very costly, we offer blowing of second optical cable into HDPE sub-duct already occupied by the existing one. For that process a Y shaped adapter is used. When installation is completed the subduct opening is closed by repair duct.
    • It is difficult to mathematically calculate the blowable distance of a second cable, however the field experience shows that distance is about 50% of common distance.
    • Blow a third cable is still not possible.
  • Testing and values analysis according to specification of TA 117 SPT Telecom
