Description

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

Applications

In according to environmental conditions, Optical fibre 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 OPGW.

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

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