ITU sets international standard for sealed fiber optic closures used outdoors

ITU sets international standard for sealed fiber optic closures used outdoors

"The user has the flexibility to select the applicable installation environment, the desired level of optical stability and a level of circuit separation. It is also possible to modify the basic environmental test settings according to specific local needs by specifying additional requirements."

Closures are a mundane and frequently overlooked portion of fiber optic networks. They're used to seal up splices and, increasingly in FTTH (fiber to the home) and cable TV systems, optical splitters.

The better closures are usually worth paying extra for because they allow field installers to assemble a fiber node faster resulting in lower labor costs. They also protect the fiber from the elements and allow for future safe access to unused fibers for reconfiguration without damaging other fibers carrying live traffic.
