Usage and characteristics
Optical fiber closure is used for protecting the optical fiber fusion splicing head between two different optical cabers;a reserved section of optical fiber will be kept in the closure for maintenance purpose. In according to environmental conditions,Optical fiber closure is divided into Closure for pole and Closure for tower; in according to the different shell material ,it is divided into plastic Closure and Metal Closure. 1)Plastic Closure is used for ADSS Cable 2)Compare with Plastic Closure,Metal Closure has many obvious advantages as mechanical strength ,leak tightness and corrosion resistance .it’s usually used for OPGWDiagrammatic Drawing of Installation
