15.3 Selecting fiber-optic cables

15.3 Selecting fiber-optic cables
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?
● Installation of an outdoor cable directly underground?
● Does the fiber-optic cable have to be water-proof?
● Which temperatures influence the installed fiber-optic cable?
Cable lengths up to 10 m
The synchronization module 6ES7 960–1AA04–0XA0 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 cable per fault-tolerant system, crossed
● Connector type LC–LC
The following lengths of such cables are available as accessories for fault-tolerant systems

The synchronization module 6ES7 960–1AA04–0XA0 can be operated in pairs with fiber-optic
cables up to a length of 10 km.
The following rules apply:
● Make sure there is enough strain relief on the modules if you use fiber optic cables longer
● Keep to the specified ambient operating conditions of the fiber-optic cables used (bending
● Observe the technical specifications of the fiber optic cable (attenuation, bandwidth...).
