Thick/Fat Cylinders on HDMI cables ? What is it ? What does it do ?
 

Hello,

The "high speed hdmi with ethernet cable" I bought looks something like this:

What I want to know is what are these very thick sections on this cable ?

Looks like some kind of adapter/device is on this cable ?

What is it ? What is it named ? What does it do ?

(They look like two big fat round cylinders ?!?)

Bye,
Skybuck.

They're ferrites.

The material has to be selected for the frequency range
of interest.

These likely remove common-mode interference.
