D001 (7001)  dome heat shrinkable fiber optical splice closures can be used for the protection of various straight-through closures and branching closures. This kind of splice closures are sealed with the heat shrinkable tube, so that people can fix and seal the optical cable by heating the fiber shrinkable tube . The heat shrinkable fiber optical splice closures can be used for buried installation, manholes, holding poles, wall hanging and overhead installation.


The closure adopts heat shrinkable sealing structure.There is one big oval shaped inlet/outlet port in base.The big oval shaped port is used for the sealing of uncut straight-through fiber cable, the small ports are used for branch fiber cable and drop cable.

It adopts engineering PC plastic with high-strength to make the closure has longer life time and excellent

sealing performance.

The patented sealing structure keep good sealing performance after re-entry and re-using.

It is without cable fixing device.

The bending radius of FOSTs meet the international standard.

It could save the installation time and improve work efficiently.


Suitable for bunchy & ribbon fibers

Aerial, underground, wall-mounting, hand hole-mounting, pole-mounting and duct-mounting
