Mechanical Sealed Vertical Dome Enclosure
A fiber optic dome closure provides a secure, environmentally sealed housing for outdoor cable splices in aerial, duct, and direct-buried outside plant deployments. Designed to manage up to 144 fiber cores, this enclosure incorporates a fully mechanical sealing structure to protect optical connections against moisture and dust in harsh outdoor environments.
The fiber optic dome closure protects high-capacity fiber splices across outside plant infrastructure. Constructed from polypropylene with glass fiber (PP+GF), the enclosure withstands outdoor exposure while maintaining structural integrity. It accommodates a maximum capacity of 144 fibers utilizing up to 6 splice trays, with each tray supporting up to 24 single fusion splices.
