Ethernet ranges from the old style 10 Megabit connections to 1-gigabit connections. Most home PCs today, used as an end point termination, don't even come close to that much communication across it, due to the lack of processing power and need. Business servers are developed to handle more traffic and normally require more data information through-put.
We can, like most bell companies or ISPs, bring fiber to the home or to the X (X=where you need it). With fiber to the X communication, it breaks up your services (internet, TV, and phone) so it can be terminated to your household wiring. Ethernet, either Cat 5, Cat 5e, or Cat 6, is used today for majority of internal wiring, as it continues to show its strengths for shorter distance runs.
Before installing, be sure to plan and before planning, let us assist you in your designs. We can assist your company or technical department to design out the right realistic but futuristic voice and data network, thus allowing more expansion capabilities.
