6.5 Connecting optical cables
Optical link module

4. Close unused BFOC sockets with the supplied protective caps.
– An unused optical channel should be set to the “bus without fiber-optic link monitoring“
mode so that it does not cause a broken fiber-optic cable signal.
– Incident light from the surroundings can cause disturbances on the network
particularly, if the surroundings are very bright.
– Dust entering the optical components can make them unusable.
5. Keep to the maximum length of the fiber-optic cables and the possible fiber types, See
"Properties and functions (Page 11)" and "Technical data (Page 73)".
6. Test the quality of the link using the measurement socket after installing the optical
network. The measured values must be in the permitted range as can be found in section
"Optical channels (Page 48)".
-optic cable may be connected to an OLM that uses glass fiber-optic cable
-optic cables requires special measures.
Avoid mechanical stress such as traction, p
ressure or kinking.
urers specify minimum bending radii for fiber-optic cables both during
installation and operation. The bending radii and the requirements when laying cables
depend largely on the cable type used and must therefore be c
hecked in the instructions in
vant data sheets. Ignoring these requirements may lead to higher attenuation values
and, in the worst case (extreme bending etc.), to destruction of the fiber
-optic cable.
