Selecting fiber-optic cables

Introduction
You need to consider the following constraints and factors when selecting fiber-optic cables:
● What length of cable do I need?
● Is the fiber-optic cable to be laid indoors or outdoors?
● Is special protection from mechanical stress required?
● Is special protection from rodents required?
● Does the outside cable need to be direct-buried?
● Does the fiber-optic cable need to be watertight?
● To what temperatures will the fiber-optic cable be exposed once laid?
Rules
Observe the following rules:
● If you use fiber-optic cables, ensure sufficient strain relief at the synchronization modules.
● Adhere to the specified ambient conditions for the fiber-optic cables used (bend radii,
pressure and temperature).
● Comply with the technical specifications for the fiber-optic cables used (attenuation,
bandwidth).
Cables up to 10 m
6ES7960–1CB00–0AA5 synchronization modules are operated in pairs with fiber-optic
cables of 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
● Patch cable for indoor use
● 2 x duplex cables per S7-1500H, crossover
● LC-LC connector type
The following cables are available as accessories for S7-1500H:
