Fiber Optic Closure

Outdoor vertical dome closure, Heat shrink, 4 in 4 out



The Heat Shrink Fiber Dome Closure is designed for aerial, buried/underground above-grade, and below-grade applications; it meets the needs of anyone deploying fiber optic networks: Long haul,metro,local access, and FTTx networks. It has heat shrinkable sealing structure with 7 entrance ports on the end (6 round ports and 1 oval port).

The Dome Closure features an o-ring sealing system along with an innovative latching/locking mechanism.This combination is designed to allow simple, watertight closure sealing and re-entry.The dome closure utilizes heat shrink technology for cable sealing which helps to provide a watertight seal.

The Dome Closure is equipped with a built-in fiber management system that provides a separate area for storing, routing,protecting, and expressing buffer tubes, single and ribbon fibers.The hinged splice trays include a modular spice holder design which allows them to accept single fusion, single mechanical, and various mass fusion splices(4/6/8/12 fiber ribbon) by simply replacing the splice holder or protection event mini splitter inside.



  • The body adopts modified plastic MPP, which is high strength and corrosion resistant, has a longer lifetime, and has excellent sealing performance.
  • It has 7 cable ports in total, 6 Φ20mm round cable ports,and 1 oval port, which can let in and out 1pc Φ42mm cable or 2pcs Φ20mm cables, as for a few small size cables at the same time.
  • The closure can be reopened,which is maintenance friendly. It can work well in the outdoor environment and guarantee good sealing performance.
  • Assembled with valve core and grounding device.
