particulary the possible reference clock source wasn't even mentioned.
The unclear point is, what
create new clock to sample the data means. If it's from the same clock oscillator as transmitter with unknown phase, you only need phase align, but if has also a frequency offset, permanent resynchronization is needed.

The two parts of my design are separate. The data is transmitted to the receiver via fiber and the receiver pack the received-data at higher speed then broadcast. Please see the picture attached.
The reference clock source is provided by the receiver, all the clocks transmitter need are coming from the fre-divider which the input clock is picked-up from the down bit-stream.
The receiver wants to sample the 2-16Mbit data correctly, so i said
create new clock to sample the data,because the speed of the data changes. Maybe the first method Rysc mentioned is much better.
I wonder whether these methods work properly.
