PROFIBUS Cable Types
The recommended cable is
Belden 3079A PROFIBUS Cable
This is a shielded, 150 ohm twinaxial (single twisted pair) cable. It has 22 AWG
conductors and a mutual capacitance of 9.0 pF per foot, nominal. For complete
specifications on this cable, please contact your Belden dealer or visit their website at
www.belden.com.
Alternate cable types are:
Siemens 6XV1 830-OAH10 Two Core shielded
Siemens 6XV1 830-OBH10 w/PE Sheath
Siemens 6XV1 830-3AH10 for underground burial
Siemens 6XV1 830-3BH10 trailing cable
Bosch Comnet DP #913 548 Flexible PROFIBUS cable
Bosch Comnet DP #917 201 Trailing PROFIBUS Cable
Bosch Comnet DP #917 202 Massive PROFIBUS Cable
Note: Allen Bradley “blue hose,” which has an impedance of 78 ohms, is not
recommended for this application.
Network Termination
Termination resistors are needed, as defined in DIN 19245 Part 1 section 3.1.2.5.

Generally, termination is provided in commercially-available PROFIBUS standard network
connectors. Some connector vendors provide termination capability in the connector and
a switch on the connector to enable/disable termination. Some connector vendors provide
both terminated and unterminated connectors.
