Rules
Observe the following rules:
• If you use fiber-optic cables, ensure sufficient strain relief at the synchronization modules.
• Comply with the technical specifications for the fiber-optic cables used (attenuation,
bandwidth).
Cables up to 10 m
Use the synchronization module 6ES7960–1CB00–0AA5 in pairs with fiber-optic cables 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
• 2 x duplex cables per S7-1500H, crossover
• LC/PC or LC/UPC connector type
The following cables are available as accessories for S7-1500H:

10 m
Cables up to 40 km
Insert the synchronization module 6ES7960-1FB00-0AA5 or 6ES7960-1FE00-0AA5 in pairs
with fiber-optic cables up to 40 km.
For cables over 10 m, you will need to have the fiber-optic cables custom-made. Select the
following specifications:
• Up to 10 km: Single-mode fiber (mono-mode fiber) 9/125 µ (fiber specification OS1 or
OS2)
• From 10 km to 40 km: Single-mode fiber (mono-mode fiber) 9/125 µ (fiber specification
OS2)
In exceptional cases, you can use the cables available as accessories in lengths of up to 10 m
for commissioning and testing purposes. For permanent use, however, you must use the
cables specified in the table below with single-mode fibers.
