The Dome Closure protects fiber optic splices in outdoor and underground environments. Its dome-shaped structure houses and safeguards spliced fibers while maintaining reliable performance in demanding conditions. The closure features a patented segmented end plate allowing independent access to each cable port without disrupting adjacent cables, and a hinged collar system enables quick reentry without special tools. An integrated air valve facilitates flash testing of the closure seal.
The flexible grommet sealing system accommodates a wide range of flat or round cable profiles, supporting high-density splice configurations. Constructed from flame-retardant and UV-stabilized materials, the closure is independently tested according to Telcordia GR-771-CORE standards, with some models achieving Internet Protocol (IP) 68 ratings for environmental sealing. The closure operates effectively across temperature ranges from -40°F to +149°F.
Typical models measure 16 inches in length by 10 inches in width by 5.7 inches in height, with splice capacities supporting up to 120 single fusion or 288 mass fusion splices using butt/expressed splice configuration. Cable diameter compatibility ranges from approximately 8 mm to 32 mm depending on the model.
The closure supports Fiber To The Home (FTTH) deployment and back-haul networks through direct buried, manhole, aerial, or pole/wall mount installations. Mounting options include aerial, pole, wall, or below-grade configurations using optional mounting kits. Standard kits include multi-port grommets for cable entry and splice trays for organizing and protecting splices.
