A fiber optic splice closure is a protective enclosure designed to house and protect fiber optic splices and, in some cases, passive optical components. Cables must be joined due to route length limitations, branching requirements, repairs after damage, or network upgrades. Whether underground, aerial, or in manholes, splice closures are the first line of defense against environmental threats to your fiber. Whether your fiber to the home (FTTH) network design has closures in a buried or aerial environment, one thing remains the same: you need assured environmental protection and quick, incremental subscriber drops. From our experience in the field, we know that not all closures are the same.
