optical splice closures are used to distribute, splice, and store the outdoor optical cables which enter and exit from the ends of the closure. There are two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, man-well of pipeline, embedded situation etc. Comparing with terminal box,the closure requires much stricter requirement of seal. Sealing ring and air valve are required for closure, but that are not necessary for terminal box.

• 1). High quality PPR material optional, can ensure harsh conditions such as vibration, impact, tensile cable distortion and strong temperature changes.
• 2). Solid structure, perfect outline, thunder, erosion and adding resistance.
• 3). Strong and reasonable structure with mechanical sealing structure, can be opened after sealing and cab be reused.
• 4). Well water and dust proof, unique grounding device to ensure the sealing performance, convenient for installation.
• 5). The splice closure has a wide application range, with good sealing performance, easy installation, produced with high strength engineering plastic housing, with anti-aging, corrosion resistance, high temperature and high.
