PROFINET Installation Guideline for Cabling and Assembly

PROFINET cable assembly work
For multimode fibers the types 50/125µm and 62,5/125 µm are
commonly used. Please observe: When connecting a transmission line
from different section, that only section of the same type are put
together. Otherwise you will experience additional connection loss at
the joints due to the different diameter of the core of the fiber.
2.2.6 Assembly and safety instructions
• The assembly of the thin glass fibers requires a high degree of precision that
can only be obtained using special tools and training.
• When glass FO cables are used only occasionally, it is normally more cost
effective to use ready-made cables. These are available from the cable
manufacturers in various lengths.
• When using glass FO cables more frequently, connector manufacturers can
often advise on tools and training for their connectors.
Do not leave the waste of glass fiber assembly scattered around.
The thin wires of the fiber optic cable may cause injuries. Dispose of
all glass fiber waste safely.
Insert the connector into the PROFINET device only after having
completed the cable assembly. An unfinished connector assembly
can damage the optical interface of any device to which it is
connected.
Before mating an optical connector examine the optical contact end
face with the appropriate tool: the surface must be clean. This
means no scratches, pits or debris. Such defects could damage the
PROFINET device interface and/or degrade the communications.
Special tools are required for the assembly of glass FO cables. These tools are
always optimized for a specific connector type and can only be used with this type.
Suitable tools, so-called “assembly packages“, are offered by the connector
manufacturers. Training is also required.
