Maximum cable lengths
When using copper cables, the maximum size of a PROFIBUS segment depends on the
transmission rate.
If these lengths are not sufficient for your application, you can expand the network by using
repeaters. You can achieve a maximum size by cascading up to nine repeaters.

PROFIBUS FastConnect system
PROFIBUS FastConnect (FC)
PROFIBUS FastConnect is a system for fast and easy fabrication of PROFIBUS copper
cables.
The system consists of three components:
●
FastConnect bus cables for quick mounting
●
FastConnect stripping tool
●
FastConnect bus connector for PROFIBUS with insulation displacement method
FastConnect bus cables and stripping tool
The special design of the FastConnect bus cables allows for the use of the FastConnect
stripping tool to accurately strip away the protective jacket and the braided shield in one
step. The connection of the prepared cables takes place in the FastConnect bus connectors
using the insulation displacement method.
All PROFIBUS FastConnect bus cables can also be connected to the conventional bus
connectors with screw-type terminals.
