Pressure
Do not exert any pressure on the cable, for example, by the inappropriate use of clamps
(cable quick-mount) or cable ties. Your installation should also prevent anyone from stepping
onto the cable.
Influence of heat
Fiber-optic cables are highly sensitive to direct heat, which means the cables must not be
worked on using hot-air guns or gas burners as used in heat-shrink tubing technology.

Selecting fiber-optic cables
Check or make allowance for the following conditions and situations when selecting a
suitable fiber-optic cable:
● Required cable lengths
● Indoor or outdoor installation
● Any particular protection against mechanical stress required?
● Any particular protection against rodents required?
● Can an outside cable be routed directly underground?
● Does the fiber-optic cable need to be water-proof?
● Which temperatures influence the installed fiber-optic cable?
Cable length up to 10 m
The synchronization module 6ES7 960–1AA06–0XA0 can be operated in pairs with fiber-
optic cables up to a length of 10 m.
Select cables with the following specification for lengths up to 10 m:
● Multimode fiber 50/125 µ or 62.5/125 µ
● Patch cable for indoor applications
● 2 x duplex cables per fault-tolerant system, cross-over
● Connector type LC–LC
Such cables are available in the following length as accessories for fault-tolerant systems:
