FoxyRick said:Hi,
Yes, white light can travel through fibres, at least the ones I use (digital audio).
As to why, it's more like "why not?". White light is just a mixture of wavelengths that the eye (or rather the brain) understands as "white". Each of thses wavelengths can travel through a fibre together, just like they do through a sheet of glass.
Cheers,
FoxyRick.

arunmit168 said:almost, in all applications an electrical signal is at first converted to optical and then allowed to pass thro the fibre... correct me if i am wrong so inorder to produce an optical white light... it means that an electrical signal with "all frequencies" must bethe source which is being converted to optical? am i interpreting right? is there such a relation existing between the two? or is this a crap? pls explain... if not.. then is this theoretically possible? hope not!

I ask this because I found out when I am insides elevator (lift), my cellular phone receives no signal.
djalli said:No it is not off-topic.
What happens in International Space Station? Why Russian and American Astronauts are never affected by cosmic radiation?
It does more involve a lot of effort to build a box (elevator?) to withstand cosmic radiation.
But explanation of receiving no cellular signal, which are weak compared to cosmic radiations (FCC is more powerful!), stands of location of elevator in reference to satellite but also consider the Famous Gauss Derivation "inside an empty metal shell EM forces are zero."
