Help my with my Graduate Project's Idea to make it real by using FPGA

thank you for posting sir

lets say i decide to make my project work with Ethernet

i have NanoStation Access point to receive the internet signal

and its contain Ethernet Port

so can i encode the signal from nanostation and then send it via optical fiber to the second station to decode it and send it to my PC's Ethernet port

this will let me send the signal over 100 m

is it possible

or the Ethernet port in FPGA board as like USB Port

it didn't have the ability to decode any type of signal from any device that have Ethernet port

thank you very much
