Demarcation Points (Demarc)

Question: What’s demarcation points anyway?

 

 

Answer: The term “demarcation points” (also called demarc), is the point within a facility, property or campus where a circuit provided by ISP or Telecom, terminates. Past this point, the customer must provide equipment or further vertical & horizontal cabling if needed. Maintenance and  equipment past demarcation points is the customers responsibly.

Testimonials

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
