Effect of magnetic & electric fields on fiber cable data transmissions
In the last few days of getting the BSNL folks to setup the FTTH connections, I've been messing around with the fiber cables and have been amazed by the technology. The most obvious question is whether the magnetic and electric fields affect the fiber cables and have any adverse effect on their data carrying capacity?
I checked online and found a research paper on the topic : #-Link-Snipped-#.
The paper finds out that it's the orientation of the electro-magnetic fields that may have effect which is quite noticeable in case of the electric fields and not very significant in case of the magnetic fields.
It would be great if someone can post an insight on the topic.

Abhishek RawalFOCs are immune to any adverse effect of magnetic field & electric field 'cuz the transmission is in form of light(photons) & not current. -
Kaustubh KatdareRight, that's what I initially read until I stumbled upon the paper that studies this effect. I couldn't make out much from the paper (didn't spend lot of time reading it) but it seems that the magnetic and electric fields do tend to affect. But it could be the larger magnitude of electromagnetic fields that affect these.

Jeffrey ArulrajHow come yet to go through the paper but in the fibers don't data transmitted are in the form of optical signals which have least proximity to magnetic and electric fields
-
Jeffrey Arulrajthere is interference probability in very high levels of electric field having frequency in the order of light or an equivalent magnetic field can disrupt to an extent I guess

aruncharyif magnetic field effects the optical fiber means it is fault of construction of CLAD which is highly insulted so no chance of field effects on fiber and one more thing fiber carries the optical signal so light as no effect in magnetic filed and also in an electric field.
before fiber came for real world working all of fiber vendors (manufacture) went for many tests like electrical, mechanical pressure,magnetic field ,etc,then only they out the fiber to market, if any thing happens means it is because of poor cladding construction and faulty fiber. -
Jeffrey ArulrajWell do you mean Em waves cannot be created by oscillations of Electric and magnetic fields then pal #-Link-Snipped-#
-
aruncharyi couldn't understand your point my pal...
-
Jeffrey ArulrajElectromagnetic oscillations can be produced using Electric and magnetic fields perpendicular to each other
-
aruncharyyes then.ok i got u r point, it wont much effect on fiber,...
-
Jeffrey ArulrajYup I clarified with it pal the effect is similar to super positioning of AC and DC signal the effect can be easily reversed to get back the original light signal

aruncharyyes jeffrey............
