It removes electrical noise from the network and lowers the noise floor and interference.
Use with your router, switch or directly in the wall socket for Ethernet.
How much benefit it provides is certainly dependent on how "dirty" your own Ethernet signal is to begin with. Likewise, it can vary from system to system i.e. how sensitive it is.
Ideal for products that connect to the USB port such as computer servers, hard drives, mixing desks, etc.
1. reduces RFI/EMI noise by up to 40 times.
2. reduces jitter + information errors
3. rebalances the USB signal
4. USB3.0 (backward compatible)
