Network Acoustics ENO filter


Good morning everyone
I would like to buy a "Network Acoustics ENO1" network filter that I found used for about 350 euros.
However, I read that this filter works up to 100 Mbps by cleaning only four of the eight conductors of an Ethernet cable, unlike the subsequent ENO2 model that works up to 1Gbps and cleans all eight conductors of the Ethernet cable.
At home I use fiber optics that normally travels in download at about 600/800 mbps and in upload at about 500 mbps.
In my case would the old ENO1 version still be useful or do I have to buy the new ENO2 to get decent filtering given the speed of the network?
Another question, could the Jcat XE net card network card present in my PC (music server) or the Cisco Business 110 switch that is placed between the Jcat and the router conflict with the Network Acoustics network filters or cancel out their advantages?
Thank you
Alessandro

I have had the “ENO1 system” (filter and ethernet cable) for a few years between my audio room’s switch and a Wolf Audio Alpha3SX server on a managed network.  It is limited to 100 Mbps according to the network management software interface but this has been a fully adequate transmission speed. I have had no issues with music streamed from the internet or from my NAS. 

I don't understand the duplication of filters when you already have the JCAT net card. I also use the XE card in my custom build server, absolutely no need for further net filtering. You can improve the XE further with external power via LPS and nice DC cable, I use Uptone JS2 and custom build DC cable. Quality AC cable to LPS also helps. Spend your funds elsewhere.
