Title: doubts ethernet NIC
Post by: luispolanco on November 25, 2021, 03:32:43 PM
I have a question, it may be stupid

but I have that doubt

I have an ethernet card for fiber optics, if my ethernet card is 1 gb / s I think that is the bandwidth of the interface

and my fiber optic is 10 gb / s that is, my cable

How would the traffic be for the 10gbps or only 1 gb of bandwidth of the interface passes ???

Hi,
The cable is just a cable. The 10gb comes from the transceiver. Having both sides running 10gb transceivers will achieve a 10gb link.

Does that explain well?

... adding to it, if only one side runs slower, then the speed drops to that of the slower endpoint in the link.
