This is untrue, it is done to decrease magnetic field strength. Since photons are uncharged they are not affected by magnetic fields, and since photons are created by electric fields in AC current, not magnetic fields this would not decrease their formation rate either.
can BNC CCTV be wired to CAT5/6 cable? i thinking to hook up 2 BNC CCTV Camera in a CAT6 so eliminate cables, it that possible or safe? the camera has 4wire, 2 data and postivie n negative DC power.
so based on those different pitches in those twists can i say if you don't follow the A or B standards of color coding when socketing, your cables in long ranges gonna have less data transfer rate and basically you will mess with the network if you don't follow the standard.
Hossein, that’s a great observation. At lower speeds ( like 10/100 Mbps) it may not be a big effect. But at 1, 2.5, 5 and 10 Gbps it’s likely to increase error rates.
Electron movement creates a magnetic field, magnetic fields can change the direction of electron motion, and when two magnetic fields with flux lines pointing in opposite directions converge the strength of those two magnetic fields decrease. So since (as can be seen with the right-hand rule) two wires with current moving in the same direction create magnetic fields with flux lines pointing in opposite directions, these wires are wrapped around each other so the strength of the magnetic fields around those wires decreases. This decreases how much those magnetic fields interact with electron motion in other wires. That's all there is to it.
Wait, don't the two wires have current moving in different directions? Since one wire is transmitting and one is receiving? I really want to understand why crosstalk occurs, and I still don't understand it quite yet.
This is the same idea as Humbucking Guitar Pickups which have two pickup windings per string wound in opposite directions to each other. This cancels the noise.
Didn't know each cable had twists of varying lengths to mitigate the magnification of emfs. Thanks for the quick rundown :)

Appreciate the knowledge! Hopefully eventually I'll fully understand why the twist prevent crosstalk!
John. I think there’s a lot of science in there. Probably mire than I can explain
I basically knew why and now I know exactly why. Thank you !
I'm sure there is a lot more science below the surface, but I didn't want to pretend to know it. Thanks for commenting and thanks for watching! :-)
Great explanation thabk you 💯
Its also to keep the impedance the same. If theres a secouction of high impedance it can reflect data in the opposite direction down the cable.
So, in your opinion, would it be fair to say the twists are homogenizing the impedance through out the span?
Thank you ...

Yes, I believe they make a bnc-to-rj45 just for that situation.
Thank you....................
Good video, Thank you.

I thought the pairs were twisted so that any noise picked up would be equal on both wires and then cancelled out at the differential receiving amp.
Let's twist Optic Fibres!
(bad joke)
ahahaha... that would be a good one to play on a rookie. great idea! 😄
Dope

@@aunmaqsood3129 brother have you got your answer then please explain it for me. i was searching for it from an hour.
If you know anything about lorentz law, you'll already know why :)
hey, thanks for sharing that. maybe I will look into that.
Is this a law that forbids selling straight wires to support coper mines profitability? That Lorentz guy doesn’t care much about our planet.

Excellent point! 😎🎸
