Product Introduction

144F Dome Type Fiber Optic Joint Box Closure

An optical fiber splice closure, also known as an optical cable splice box or fiber joint box, is part of the mechanical pressure sealing joint system. It is a splicing protection device that provides continuity of optical transmission, sealing, and mechanical strength between adjacent optical cables. It is mainly used for straight-through and branch cable connections of optical cables with various structures, employing laying methods such as overhead, pipeline, and direct burial.

This Fiber Joint Box features a dome-to-base design and is sealed with a clamp and O-ring system. It offers two types of optional, hinged trays for access to any splice without disturbing other trays. It provides fast and reliable sealing performance and is easy to repackage multiple times.
