Funziona una bomba

l'ho installata su pfsense per collegarlo ad uno switch mikrotik in 10G. Il sistema l'ha visto senza nessun problema e le performance sono ottime. La consiglio per la sua facilità d'uso e per il prezzo.

Affordable next-generation networking

Arrived within estimate and product as described. For those interested, these seem to ship with SFP vendor locking disabled, so non-Intel SFP should work.
