Figure 7-12 Design of the fiber-optic ground cable
Fiber-optic ground cable 6XV1 873-2G/3GT**/6GT**
The fiber-optic ground cable duplex cable contains 2 multimode graded index fibers
50/125 μm.
The round cross section of the cable makes it easier to seal cable feedthroughs.
The outer jacket is labeled "SIEMENS SIMATIC NET FO Ground Cable (PROFINET Type C)
2G50/125 6XV1 873-2G" as well as having meter markers.
Properties
The fiber-optic ground cable duplex cable has the following properties:
● Designed for 800 N permanent tensile strain
● No silicone
● Available in meter lengths for up to 2000 m
● Available preassembled with 4 BFOC or SC connectors in fixed lengths up to 300 m
● Resistant to mineral oil
● Resistant to grease
● Equally suitable for PROFIBUS and PROFINET (outer jacket green)
Use
The fiber-optic ground cable is a standard cable for laying directly in the ground, in pipes,
cable channels or on cable racks, also suitable for cable ladders.
