Flexible fiber-optic trailing cable

SSpecially designed for non-stationary use, for example with moving machinery

SIENOPYR duplex marine fiber-optic cable

SHybrid cable consisting of two fibers and two additional copper wires for fixed installation on ships and offshore facilities

SIMATIC NET Standard Fibers

In glass fiber-optic cables, SIMATIC NET uses a fiber with 62.5 ∝ m diameter as its standard fiber. SIMATIC NET bus components are ideally matched to these standard fibers allowing large distances to be covered while keeping the configuration rules simple.

Simple Configuration

All the descriptions and operating instructions for SIMATIC NET bus components contain information about the distances that can be covered with the standard fibers described above. You can configure your optical network without complicated calculations using simple limit values (refer to Chapter 3 “Network Configuration”.

Guidelines for Laying Cables

You will find information about laying SIMATIC NET glass fiber-optic cables in Appendix C in this manual.
