Demarcation enclosures offer protection for important telecommunications equipment — they aren't the place to skimp on quality. At Multilink, we carry a variety of demarcation enclosures and can custom-build new ones so that you can find the ideal fit for your application. We design, manufacture and test these plastic demarcation enclosures according to standards from the ISO 9000 Series and are always working to meet your needs in innovative ways.

Let's take a closer look at demarcation cabinets and the solutions we have available.

What Is a Demarcation Cabinet?

A demarcation cabinet is the point where third-party customer-premise equipment, such as internet access equipment, links up to public networks, like the Public Switched Telephone Network (PSTN) in the United States. These cabinets, junction boxes or enclosures serve the physical purpose of protecting the connection points and cables from unauthorized access, electrical damage, water, insects and ultraviolet (UV) rays. They also have more logistical benefits, like delineating responsibility for wiring, equipment and maintenance.

These weatherproof enclosures are regulated by the Federal Communications Commission (FCC) because they need to meet stringent protection requirements for telephony demarcation. They can come in a range of styles to suit different environments and aid in security and cable management, as well as more specialized demands.

Typically, demarcation cabinets are used for organizations, campuses and multifamily dwellings. The demarcation point for residences can be as simple as the place where the coaxial cable or other wiring enters the building. 

Demarcation cabinets usually consist of a tough, impact-resistant thermoplastic alloy, with a weatherproof cover design and seals. They may also have room inside to allow for a wide bend radius and to store enclosure accessories like extra cables, filters, splice trays, splitters, amplifiers and more.

What Is a Fiber Demarcation Box?

A fiber enclosure is a type of demarcation cabinet, housing the demarcation point between the customer premises equipment — like routers, Voice over Internet Protocol (VoIP) gateways and switches — and the fiber optic cable of the local access provider. It creates a secure space for splicing, storing, splitting and otherwise handling fiber optic cable.

RNI Boxes

We offer various sizes of RNI boxes in single and double door configurations. Our engineers develop our RNI boxes with UV-stabilized materials for years of outdoor service. Multilink RNI boxes deliver features such as:

  • Multiple adapter assembly and mounting bracket options
  • Easy mounting with FlexGrid™ technology
  • Better cable management with Velcro® straps

 

Steel Multiple Dwelling Units

In applications involving multiple dwellings, a steel multiple dwelling unit (MDU) protects fiber optic and coaxial cables. Our MDU designs minimize pry points to protect their contents from theft or tampering. Multilink MDUs provide the following benefits and features:

  • Integrated electronic components and wiring in accordance with Six Sigma standards
  • Available in various materials and knockout styles
  • Mounting styles that include ground, wall, pole and unistrut

 

Multimedia Enclosures

Multimedia distribution enclosures (MDEs) provide a centralized location for distributing and installing multi-play services. They work well with wireless and wired connections for in-premise installations, allowing them to function well as OTN cabinets and in both business and residential applications. The advantages of our MDEs include:

  • Adaptable to multiple network technologies
  • Plastic construction for reduced electrical interference
  • Improved heat dissipation through built-in louvers
