BMW 7 Series: Notes On Handling Optical Fibres
IMPORTANT: To avoid damage when handling optical fibres, comply with the
following
points:
- The minimum permitted bending radius is 25 mm
- Do not subject optical fibres to compressive and tensile load
- Protect optical fibres against the effects of heat > or =85 ºC (e.g.
during
welding work, drying work with infrared heater or hot air blower)
- Fibre-optic cables are permitted to show only one junction point
(bridge),
replace fibre-optic cables if necessary
NOTE: The optical fibres are colored differently as follows:
- Green = MOST (M edia O riented S ystems T ransport) optical fibre
- Y ellow = ISIS (I ntelligent S afety and I ntegration S ystem)
fiber-optic
cable
- Orange=repair fibre-optic cables
Follow instructions for processing cables and optical fibres.
NOTES ON HANDLING WIRING HARNESSES AND CABLES
The following applies in general
To avoid damage, observe the following instructions:
- Avoid compressive and tensile loads
- To ensure professional repairs, perform repair work only with
BMW-approved or recommended special
tools and spare parts
- Make sure cables are laid without kinks or abrasions
- Ensure non-contacting routing at sharp-edged body parts; use edge
protection if necessary
- Secure additionally laid cables/leads with cable ties
The following additionally applies
Shielded lines (coaxial lines):
IMPORTANT: Shielded lines may not be repaired!
- This may lead to indifferences in noise radiation and interference
immunity at contact points in the shield
- To satisfy the requirements of the type approval, it is essential to
replace
shielded cables completely
Fibre-optic cable:
NOTE: Fibre-optic cables are colored differently as follows:
- Green = MOST (M edia O riented S ystems T ransport) optical fibre
- Yellow = ISIS (I ntelligent S afety I ntegration S ystem) optical fibre
- Orange=repair fibre-optic cables
IMPORTANT:
- Optical fibres may only reveal one separation point (bridge); renew
optical fibre if necessary
- Smallest permissible bending radius is 25 mm
- Avoid effects of heat > or = 85 º
Treating cables and fibre-optic cables: see TREATING CABLES AND FIBRE-OPTIC
CABLES.
FlexRay:
It is possible to repair the FlexRay. In the event of damage, the cables can
be joined with conventional BUTT
CONNECTORS AND HEAT-SHRINK HOSES.
NOTE:
- FlexRay lines may only reveal one separation point (bride); renew
complete line if necessary
- The cable is a twisted cable. If possible, maintain twisted cable
after repair

NOTES ON HANDLING WIRING HARNESSES AND CABLES
The following applies in general
To avoid damage, observe the following instructions:
- Avoid compressive and tensile loads
- Make sure cables are laid without kinks or abrasions
- Ensure non-contacting routing at sharp-edged body components; use edge
protection if necessary
- Secure additionally laid cables/lines with cable straps
The following additionally applies
Shielded lines
Contact points in the shield can cause problems with regard to noise
radiation and interference immunity.
Consequently, distinctions have to be drawn between the following types:
Coaxial line
- Shielded RTK031 coaxial lines may only be repaired with special crimping
tool for repairing the coaxial
line RTK031.
CVBS lines
- CVBS lines may not be repaired.
- CVBS lines must be replaced in their entirety.
HSD lines
- HSD lines may not be repaired.
- HSD lines must be replaced in their entirety.
Optical fibre cable:
NOTE: Optical fibre cables are colored differently as follows:
- Green = MOST (M edia O riented S ystems T ransport) optical fibre
- Yellow = ISIS (I ntelligent S afety I ntegration S ystem) optical fibre
- Orange = repair optical fibre cables
IMPORTANT:
- Optical fibre cables are permitted to show only one separation point
(bridge), replace optical fibre cables if necessary
- Smallest permissible bending radius is 25 mm
- Avoid influence of heat > or = 85 º
