246 System Manual, 05/2017, A5E31622160-AC
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:

2 m 6ES7960–1AA04–5BA0
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...)
Fiber-optic cables with lengths above 10 m usually have to be custom-made. First, select the
following specification:
● Single-mode fiber (mono-mode fiber) 9/125 µ
In exceptional situations, you may also use the lengths up to 10 m available as
accessories for short distances when testing and commissioning. However, only the use
of specified cables with single-mode fibers is allowed for continuous operation.
Note
Cable up to 10 m length on the synchronization module 6ES7 960-1AB06-0XA0
Cables up to a length of 10 m are available
on order as accessories. If you use one of
these cables on the synchronization module 6ES7 960
-1AB06-0XA0 , you may see the
error message "Optical performance too high" at the call of OB 82.
