Fiber Domes, Boxes and Enclosures

Wall Mount Fiber Patch Panels

Wall Mount Fiber Patch Panels are essential when the concern is safety, security, and accessibility. Fiber connections remain orderly within the secure, centralized structure; network components are protected, inherently amplifying productivity. Moreover, Wall Mount Patch Panels are a means of simplifying maintenance in the future, furthering the overall efficiency of your fiber optic network.

Outdoor Fiber Boxes

With the changing seasons presenting new challenges for your fiber optic network to overcome, Primus Cable offers Outdoor Fiber Distribution Boxes that are designed and manufactured to endure harsh environmental conditions. Our Fiber Distribution Boxes are specially built to accommodate various amounts of simplex or duplex adapters needed for your fiber-to-the-home (FTTH), fiber-to-the-building (FTTB), or fiber-to-the-curb (FTTC) project.

Fiber Dome Enclosures

The Primus Cable Fiber Dome Closure is manufactured and specialized in its encompassing design to suffice both above and below grade applications, supporting up to 6 or more cable entries. The Fiber Dome Closure has an identifiable and distinctive gasketed split end plate system, which permits mid-accessing cable up to 1.125” in diameter. In addition, lateral or branch cables can be added to any one of four compression seal entry ports. Multiple cables (up to 6) could also be installed, utilizing multi-port grommets that are available for the Fiber Dome Closure. The Outdoor Fiber Dome Closure requires no special tools, adhesives, or mastics for installation. An integrated slack storage space and hinged trays enhance cable management. And as a final note, each Fiber Dome Enclosure includes one fiber splice tray to accelerate your fiber optic application.

Aerial Fiber Boxes

The Primus Cable Fiber Inline Closure is an enclosure manufactured to facilitate the major splice points of a network at a high capacity. This product is specifically designed to support both Inline and Butt configurations; through the use of an expansion kit, the Fiber Inline Closure is equipped with an expandable feature, conforming to application specifications. In addition, this particular item utilizes gasketed sealings along with a patented cable seal, allowing for mid-span access to the larger of cables. Our outdoor Fiber Inline Closure has the potential of being implemented within both above and below-grade applications. Lastly, each enclosure includes one fiber splice tray to initiate your fiber optic networking project.

Enhance and maintain your fiber optic enclosure through the use of our Accessories specifically engineered for Fiber Enclosures. Among our wide selection of Accessories, available are a variation of bulkhead brackets as well as grommets, adapters, and a number of specialized kits all provided to further support your fiber optic network.
