New type dome fiber optic splice closure

1. Application occasions of the product

The products of this project are mainly used in optical fiber transmission networks to mechanically protect optical cables and optical fiber connection points. It can be installed overhead, pipeline, or underground.

2. Features of the fiber splice closure project product

• The plastic parts are made of high-quality anti-aging engineering plastics, with a long service life
• The sealing of the box body and the sealing of the optical cable inlet and outlet holes are quick and simple, and can be opened and used repeatedly
• Good fiber routing design to ensure that the radius of curvature of the fiber is not less than 30MM

The product of the splice closure has a 65X40 oval inlet and outlet pipe and 6 Φ24 round inlet and outlet pipes. The overall dimensions are shown in the figure below.

• Choose the splice tray, suitable for ribbon or bundle fiber, which can be configured arbitrarily within the maximum capacity
• The splice tray has a large storage space for optical fibers, and the flip angle is up to 90°, which is convenient for maintenance and expansion.
• Grounding device and valve can be installed
• There are high quality and ordinary heat shrinkable tubing for users to choose
• There is an optical cable fixing structure inside, which makes the fixing of the optical cable safer and more reliable.

This splice closure is mainly composed of 1—cylinder body, 2—base, 3—holding hoop, 4—fiber storage tray, 5—fusion splice tray, 6—support base, 7—optical cable fixing device, 8—reinforced core fixing device, 9—seal Ring, 10-welding tray bracket, etc.

According to the different installation environment, choose different installation accessories
