Cable: Connection points

Wire /Fiber

The connection points of the category “Cable” are called wires and/or fibres depending on the technology used.

 

Coil-loading

In addition to the above characteristics, coil-loading can still be defined on the wires.

 

Extended wire characteristics

Besides the wire characteristics previously described, there are still extended characteristics that can be added by the user. These are inherited at component type level. The following extended wire characteristics can be selected:

Wire/Twin wire

Number

Additional information Copper cables

The first characteristics “Wire/Twin wire” to “Attenuation” are necessary as possible additional information for copper cables.

 

Additional information fiber Optic Cables

The next characteristics “Bundle” to “Lambda 5” are necessary as possible additional information for fibre optic cables.

 

 

For stranding type, coil-loading, bundle colour code, colour and fibre type, a large number of possible options can be self-defined by the user via the library.

 

Stranding type

The stranding type can take on e.g. the following values:

•Star quad, abbreviation: StV

•StIII phantom circuit

•Dieselhorst Martin, abbreviation: DM

•Coax, abbreviation: Kx

•Bundle stranding, abbreviation: BD

Size

Cable may contain wires of differing sizes, which then has an impact on attenuation and interconnection.

This value may also be identical for each point, yet does not need to be.

 

Coil-loading

Coil-loading has an impact on attenuation and interconnection and can only take on the following 2 values:

•Coil-loaded.

•Uncoiled.

 

Attenuation

This value is a mere planning target and should not be understood as a measurement. The specified data are only indicated for illustration purposes and dependent on the cable structure.

They are specified in dB/km.

Attenuation is then obtained using the formula attenuation [db/km]*effective cable length*helix factor.

The test frequency and attenuation [db/km] values are mere assumed values.

 

Lambdas

These values are mere planning targets and should not be understood as measurements. The specified data are only indicated for illustration purposes and dependent on the cable structure.

They are specified in dB/km.

The wave lengths of the lambdas λ1… λ5are freely configurable in the component defaults.

Attenuation is then obtained using the formula attenuation [db/km]*effective cable length*helix factor.
