Fibre optic cable

On the worldwide market there is a great variety of FO cables for different applications and purposes.

Here are some of the most important criteria to choose a suitable FO cable:

Generally FOC’s are categorized according to DIN VDE 0888

Fiberoptic Loose tube cable

Bündeladerkabel
There are significantly many different types of this cable available. Here are the main properties of a bundle conductor cable:
  • Internal cable (e.g. I-V (ZN) BH 1x12 G50/125):
    Interior cables mostly comprise flame-retardant, self extinguishing and smoke reducing sheath (FRNC or LSOH). These sheath materials are limitedly weather-proof and UV resistant, and therefore they are suitable for an interior application only.
  • External cables (e.g. A-DQ (ZN) 2Y 1x12 G50/125):
    Default comprise at least one PE-sheath, are weather-proof and UV stabilised. Therefore they are applicable for a direct burial or likewise being installed within empty tubes (Leerrohren) and exposed positions.
  • Central bundle conductor ( e.g. A-DQ(ZN)2Y 1x12 G50/125 ):
    Cables with a central bundle conductor are inexpensive cables and can be produced with up to 24 fibres. However, these cables allow for a reduced bending radius when they are laid. As they possess a smaller tensile load, they are not suitable for a subsequent air-injection of empty tubes.
  • Stranded loose tube cable (e.g. A-DF (ZN) 2Y 3x4 E9/125):
    Cables with stranded bundle conductors consist of fibre filled bundle conductors, that are individually layer – stranded around a central strength member. A cable of such configuration provides a higher mechanic capacitance, and is therefore perfectly suitable for being air injected tubes.
  • Gnawers protection (e.g. A-DQ (ZN) B2Y 6x4 E9/125):
    The protection against gnawers for FOC cables can be processed non-metallic, with glass roving respectively aramid yarns or an additional polyamide sheath. A metallic possibility to provide protection is to fit a corrugated steel tape sheath or another metallic sheathing.
    The choice of the appropriate protection against gnawers may vary according to its field of application.
  • Without gnawer protection (e.g. A-DF (ZN) 2Y 8x12 E9/125):
    Cables without protection against gnawers are suitable for interior laying respectively for the laying in self-contained piping’s

Fiberoptic Breakoutcable

LWL-Breakoutkabel
Breakout cables (I-V (ZN) HH) do not comprise fibre filled bundle conductors, but single elements (0.9mm or 2-3mm), which can be assembled directly to FOC connectors.

This kind of fibre optic cables is especially applicable for cabin- respectively in-house connectors that require more than two fibres, but should not be spliced.

Standard breakout cables are offered with up to 24 single elements of all kinds of fibre, and are also available with a larger number of fibres according to clients needs.

Fiberoptic Sensor cable

Sensorkabel
[In collaboration with a partner company we plan, develop and install FOC sensor cables and provide whole systems, which are internationally known as DTS ("Distributed Temperature Sensing"). This technology uses the temperature dependency of certain optical properties of fibre optics in order to measure the temperature along the FO cables.
  • Early fire detection
    An increase of temperature affects the fibre attenuation in such way that in-time fire detection within a radius of a meter can be ensured
  • Environmental protection
    FOC-sensor cables can depict the condition of dam walls as an early warning system, and prevent catastrophes in a case of emergency.
  • Geothermic
    These cables measure the temperature profile in geothermic depth drilling and therefore facilitate finding new sources of energy.
