Where can I find (buy) a network hub with a bandwidth of 1 Gb / s?

Question

Computer networks

From time to time there is a need to stand in the equipment gap and take a copy of the traffic, while there is no way to do port mirroring. Well, it happens. But you can put equipment in the gap.
I know that traffic can be encrypted. In this case, it doesn't matter.
Maybe someone found in the open spaces, namely hubs =)

Answer 1

And than the smart switch does not suit.
Some sort of mikrotik.
Hubs at modern speeds are evil.
Microcontrollers are cheap.
Now - only switches.

Answer 2

A hub of this speed is not possible according to the standard (and technology). You need a bridge (router in bridge mode) or a managed switch with a port in mirror mode.
Do not forget about violations of the law.

Answer 3

Nowhere. By the time speeds had grown to gigabit, hubs had died out as a class. 100Mb can be found on ebay or alibaba...maybe...
