INDOOR fiber-optic cable

S

Free of halogens, can be walked on, and extremely flame-retardant FO cable 
for use in buildings

Flexible fiber-optic trailing cable

S

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

SIENOPYR duplex marine fiber-optic cable

S

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

In glass fiber-optic cables, SIMATIC NET uses a fiber with 62.5 

µ

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.

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”.

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