Question Sending Frames to Twisted Pair

[derek wildstar]

Hi,
I was following a thread about how exactly frames are sending to the Twisted pairs of a CATe cable via a 1000 BASE T Transmission.
Someone posted this image too:



What it is says sounds a bit incosistent to me. The last part of the text says:

"Since the information travels simultaneously across the four paths, the circuitry has to divide frames at the trasmitter and reassemble them at the receiver".
Does it mean that each frame gets cut and its bits are sending in parallel through the four "ways" available? But on the other hand, the picture seems to say otherwise, that is, each and every pair is associated with a different Frame at a time .

Could you help figure it out please?
Thanks

Where did you get that diagram that is not how the physical layer of ethernet works.

I forget the details but the data encoding is called 4d-pam5 on gigabit. In effect it all 8 bits of each byte of data in parallel. It encode 2 bits into each pair and send 4 by 2 bits

I thought that. It is the reason why I decided to ask it elsewhere

.. It encode 2 bits into each pair and send 4 by 2 bits

Ok, it was the answer I expected. Thanks
