I have no clue what the hell happened here, without this no sound works(music,gongs,chimes) i'm guessing its because of this. When i put the ignition on a red light on the left one comes up blinks goes out. The right one nothing, what can i do? Thanks in advance

Yes you can splice fiber optic cables to repair them but you need special splicers and special tools to ensure the light inside the fiber is aligned.

What kind of person could i go to that does that? where to i buy the fiber optic cable? thanks

[Raptor04]

Dealer can do it.

Honestly it is probably cheaper to replace the entire harness it is a part of than it is to get all the tools to splice and/or repair that...

[Yago]

How much are the tools. And I would rather replace the entire harness but having a hard time locating where they go. So far I've traces a set of wires near the driver side under the carpet. How much further do you think they go?

[ctuna]

Probably easier to buy a new cable.
Where does that end plug in.
Or if you do not have CDC there may be some extra cables
for pre wiring already in the car and not used for 09 an earlier
models.(that you can use to replace it)

How did you discover this what part of the car is it coming from
and what kind of sound system do you have.


It would be normal for light to shine on only one side as
the other side is the return loop.

A pin on the connector housing frees the two cable for removal then
only the damaged one needs replacing.

Splicing Fiber Optic is not cheap, and the tools for it are even more expensive.

I was a PM for an electrical contractor that did some fiber splicing. Our splicing machines were $10k a piece... We did industrial type splices though so not sure what smaller splicers would cost, but im guessing in the $2-3k range.

However, it isnt too bad to pay for a splice considering the cost of tools for a fiber splice. Ask the dealer and see what they charge. Or call up some fiber companies and see if they would consider helping you.

yeah, it's pretty easy, actually. we do it all the time. you just need a clean cut, some new pins, and a connector.

no issues using mechanical splices?

BMW uses mechanical splices and connections. Why would there be an issue? These are factory parts.

Hey I just started reading the PDF file. Those wires that are cut run to the amp in the trunk. I noticed about 4 green cables are damaged. I was thinking about soldering the speaker wires. But the fiber optic ones, was thinking about replacing them. There are some wires running to nothing under the trunk. Not connected to anything. I found a panel near the side or the rear seats but it seems like the fiber optic cables run towards the head unit.
I'm in Brooklyn New York.

[Yago]

Any idea on how to remove the fiber optic wires from the connector?

X5 35D how many Um Is it from the outer casing to the core of the fiber-optic green wireharness in the back driver side near the stock amp . I bought all of the recommended parts and tools you posted . What splicing tool is recommended to splice i to the correct UM measurements.

[ctuna]

Don't know why you attempt to splice those way cheaper to buy a new one.
Not cool to bring a thread back from the past from 5 years or more ago.
What is your actual problem with the car?
What year is it?

Well, i occasionally need to repair optical cables at work and they are really simple. Just a silica or plastic tube that transports light.

We even have machine to measure light attenuation (dBm) after mending them. So i've had fair bit of experimenting with them.

Anyways there are cutters like this: https://i-fiberoptics.com/tool-detai...24&cat=cutters

Essentially it is just razor sharp blade that cuts through fiber. However the small hole makes sure damage is not spread but stays in very small region (proper positioning) and while using the handheld tiny tool it makes sure you make one clean cut.

What i'd do in this situation.
Get new razor blade.
Inspect how far fiber is from connector end, document it or do an image.
Remove fiber from connector.
Use very sharp razor blade and place it on the optical cable.
Use hammer on the razor blade and don't apply much force but the goal is to make one clean cut splicing the cable.
Hit the razor with the hammer and you've successfully removed broken part of fiber.

Next get 2000 grit sandpaper, get it wet.
Do wax-on type of round movements with the recently cutted fiber end on the sandpaper.
Keep it horizontally while sanding, occasionally inspect work until fiber end is very smooth (this step depends of good of a cut was made initially).
Inspect results, if good put optical fiber back into the connector.

Total cost = 1 razor blade + sandpaper. Probably less than 3$. You can use any object as a hammer so hammer cost doesn't count.

You've saved money and environment of another plastic piece of rubbish that probably ends up in India huge wasteland.

I have a 2013 x5 35d and two of my green most bust cables where damaged in the cargo area. I’ve cut them all and have a clean slice and everything I bought all the recommended parts. But having trouble with the optical
Waveguide socket part # (61 13 6 906 554)
Going into the optical waveguide connector part number (61 136 906535). I would buy new optical waveguide cables But wouldn’t it have to be green and not orange.
