difference between source data rate and transmission data rate?

Transmisson rates depends on the speed of the interface , size of the queue buffers I suppose. let me get back to you with proper information.

Its difficult for me also to define it but i know that transmission of high-data-rate optical signals through a micrometer-scale silicon ring resonator.Hope this definition help you.

Can anybody tell me in simple the difference between source data rate and transmission data rate?

Hello,

Source Data Rate refers to the rate at which the source is producing the data i.e. It reflects the capability of the source that how many bits/bytes it can pump in one second.

Transmission Data Rate refers to the capability of the transmission medium to carry the produced data through it. For a better understanding you can view the transmission medium analogous to a pipe carrying water where water is analogous to the data stream. The THICKER the pipe, the higher is the transmission bandwidth. Mediums with good transmission bandwidth are: Optical Fibers.
They use optical light waves to transmit the data using reflection and Total INTERNAL REFLECTION.
Thus Transmission Rate is limited by the medium u are using to propagate the data produced by the source.

Hope this analogy is helpful to you.
