The fiber closure should reflect its copper cousin's architecture, design and simplicity, but meet the long-term needs of fiber maintenance. These features can maximize the use of the same technical staff, similar tools and inventory to meet any combination of copper and fiber optic networks. The ideal enclosure can be used to handle discrete or ribbon fiber networks, as well as loose buffers and individual pipelines, and allows easy rearrangement of the fiber without violating the fiber bending radius. If a larger closure is required and the installation is allowed without damaging the integrity of the joint or cutting the fiber, the closure will be designed to improve the existing connector.
The fiber closure must be rugged to provide maximum protection for the environment. Water, insect and polyolefin insulated conductor degradation threatens the integrity of copper and fiber connectors. Special gels, adhesives, gaskets, stretching and retraction tubes, and heat-shrink tubes placed at the bottom of the exposed units of the cable are good methods of forming a hermetic seal to ensure maximum protection even in severe cases.
Any part of the closed application cost is the time and manpower to install and re-enter the device. With the increase in the number of fiber, which may be significant savings. In general, the fewer components are installed and re-entered. A housing with a mechanically fixed, rather than heat-sealed, removable housing eliminates the need for expensive and bulky power supplies. In addition, you need to shut down to minimize multiple re-entry kits and specialized tools.
With the development of fiber optic networks, the flexibility of the unit is another major requirement. Due to the large differences in the fiber architecture, it is necessary to equip the unit to handle some wiring to ensure a smooth transition when splicing and change are required.
