Fiber Closure uses a high-strength engineering plastic housing that withstands harsh conditions such as vibration, shock, tensile cable deformation, and strong temperature changes, and opens the seal with reusable parts to ensure good airtightness. No special tools are required, making it easy to install and open copies. The Fiber Closure is housing that acts as an optical termination point between the optical distribution cable and the optical drop cable. It is designed to support antenna fiber access networks, especially FTTH. The aerial enclosure consists of two separate compartments: a distribution cable connector section and a drop terminal section. The distribution cable connector portion houses the fiber optic connector and stores a buffer tube or ribbon fiber slack base, and the lead terminal portion houses a 1:8 splitter and eight drop cables. It can be extended to 1:16 splitter and 16 branch cables. The main features of Fiber Closure: 1.4 ports for distribution cables and 16 ports for branch cables 2. Internally installable 1×8 PLC splitter 3. In-line antenna closing device for outdoor use 4. UV protection, waterproof, anti-aging 5. Compact design and lightweight
