1.5.3 Supported Fiber Optic Cables - Siemens SIMATIC NET RUGGEDCOM MX5000RE Equipment Manual

Introduction
1.5.3 Supported fiber optic cables
reliable, error-free data communication, new and pre-existing communication paths
should be verified for TIA/EIA-568-A compliance.
The following table summarizes the relevant cabling standards:
Follow these recommendations for copper data cabling in high electrical noise

Data cable lengths should be as short as possible, preferably 3 m (10
ft) in length. Copper data cables should not be used for inter-building
communications.
Power and data cables should not be run in parallel for long distances, and
should be installed in separate conduits. Power and data cables should intersect
at 90° angles when necessary to reduce inductive coupling.
Shielded/screened cabling can be used when required. Care should be taken to
avoid the creation of ground loops with shielded cabling.
