Demarcation FAQs

What are different types of Demarc devices?

Network Interface Device (NID)

The NID is the most basic demarc. The fiber technicians install the NIDs outdoors, giving technicians 24/7 access. A standard, residential NID is small and weatherproof, and it includes fiber termination, a test jack, and circuit protection.

Optical Network Terminal (ONT)

An ONT is a demarc that directly communicates with an internet service provider with fiber optic cabling. Our installation technicians connect cabling from the NID on the outside of your home to the inside where they will connect the ONT. The ONT is the device that handles the Wi-Fi and hardline connections that connect you to the internet.

The ONT transmits on a 100% fiber optic network at the speed of light. The ONT converts these signals into electrical signals that your devices can understand. Additionally, any signals that you send out (such as uploading a video, sending an email, or making a phone call) are sent the same exact way. Thus, providing fast and synchronous upload and download speeds.

Where can I find my Demarc?

The demarc is typically located in a place that is accessible for technicians. While the exact location can vary, here are some common locations for a demarc:

  • On the outside of the building near an electrical meter
  • On the inside near an electrical panel
  • On the inside on a wall that is adjacent to where the fiber line enters the house
What is a Demarc?

Demarc is the abbreviation of “demarcation point”. Another name for a demarc is an MPOE (minimum/main point-of-entry). This is the physical location where the customer’s equipment connects to the service provider’s equipment.

The demarc determines who is responsible for installation, maintenance, and repairs. For any equipment located before the demarc, it is the service provider's responsibility. For any equipment located after the demarc, it is the customer’s responsibility.
