Specification 

Optical fiber closure is used for protecting the optical fiber fusion splicing head between two different optical cables; a reserved section of optical fiber will be kept in the closure for maintenance purposes.

Optical fiber closure has some excellent performances, such as good sealing property, waterproof, moisture-resistant, and incorrodible after being installed on the electric power line.

Optical fiber closure is divided into two types: joint box and Terminal Box, joint box is used for protecting the connection between two optical fiber cables, while Terminal Box is used for a cable terminal or to protect the connection between optical fiber and jumper.

According to environmental conditions, Optical fiber closure is divided into a Closure for the pole and a Closure for the tower; 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 OPGW.
