12.3 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:

Cable length up to 10 km
The synchronization module 6ES7 960-1AB06-0XA0 can be operated in pairs with fiber-optic
cables up to a length of 10 km.
The following rules apply:
● Make sure of adequate strain relief on the modules if you use fiber-optic cables longer
than 10 m.
● Keep to the specified environmental conditions of the fiber-optic cables used (bending
radii, pressure, temperature...)
● Observe the technical specifications of the fiber-optic cable (attenuation, bandwidth...)
