Selecting fiber-optic cables
Introduction
You need to consider the following constraints and factors when selecting fiber-optic cables:
●
What length of cable do I need?
●
Is the fiber-optic cable to be laid indoors or outdoors?
●
Is special protection from mechanical stress required?
●
Is special protection from rodents required?
●
Does the outside cable need to be direct-buried?
●
Does the fiber-optic cable need to be watertight?
●
To what temperatures will the fiber-optic cable be exposed once laid?
Rules
Observe the following rules:
●
If you use fiber-optic cables, ensure sufficient strain relief at the synchronization modules.
●
Adhere to the specified ambient conditions for the fiber-optic cables used (bend radii,
pressure and temperature).
●
Comply with the technical specifications for the fiber-optic cables used (attenuation,
bandwidth).
Cables up to 10 m
6ES7960–1CB00–0AA5 synchronization modules are operated in pairs with fiber-optic
cables of up to 10 m.
Select the following specifications with cable lengths of up to 10 m:
●
50/125 µ or 62.5/125 µ multimode fiber
●
Patch cable for indoor use
●
2 x duplex cables per S7-1500H, crossover
●
LC-LC connector type
