A member of dome closure, used for the products’ straight through
connection in the optical transmission process, provides protection for
the joint connection. With four small round ports and one large round
port, it adopts threaded mechanical seal, can be used for aerial, pole mounting, wall-mounting and underground application. It is excellent in
sealing performance, easy for installation, and has wide application.
II. Feature
► All performance indicators meet the requirements of the national YD
814.1-2004 closure standard;
►Three-in and three-out cable ports, there are 5 round cable holes (4
small & 1 large), which suit for the access of Φ7∼Φ22 cables;
► The outer box body is made of high-strength engineering plastics, It
has features of light weight, high mechanical strength, anti aging,
strong corrosion resistance, lightning resistance, and long service life.
► Stacked structure splice tray and independent insulation grounding
device make it flexible, convenient and safe for the optical fiber core
configuration, expansion and the cable grounding.
► The splice tray is provided with a dedicated slot for optical splitter,
which is used to fix two 1:8 PLC optical splitter.
