What is an electrical Interface?

Hi,

We as transport engineers have this first things to deal with , optical electrical interfaces, I myself had number of doubts regarding the the actual difference between them.
After my work experience in RAN domain i tried to find the difference between them and there impact in terms of signal to noise ratio and cost requirements.

Electrical Interface- When electrical pulses are used to represent binary 1s and 0s then the interface is electrical interface. Electrical signals need medium to travel like any other pulse, but i case of electrcal from transport part we have medium generally as CAT6 , old thicknet/thinnet coax cables. These cables or mediium has high attenuation as compaired to fibre so channel capacity is gerenally less in terms of electrical signals.As ethernet isn't actually a cable as it's often referred to, it's a data link layer protocol, ethernet networks can be created over different physical mediums.
