Cable: Connection points
The connection points of the category Cable are called wires and/or fibers depending on the technology used.
In addition to the above characteristics, coil-loading can still be defined on the wires.
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:
Characteristic |
Type |
Description |
|---|---|---|
Wire/Twin wire |
Number |
Numbering method of wire/twin wire. |
Location |
Number |
Numbering method of place in which the twin wires are located. |
Phantom circuit |
Number |
Numbering method of phantom circuit for each location. |
Stranding type |

The first characteristics Wire/Twin wire right down to attenuation are necessary as possible additional information for copper cables. |
The next characteristics Bundle to Lambda 5 are necessary as possible additional information for fiber optic cables. For stranding type, coil-loading, bundle color code, color and fiber 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.
