SMC Optical Distribution Box

SMC Optical Distribution Box

Fiber optic distribution boxes, also known as fiber optic cable joint boxes or splice enclosures, are essential components of fiber optic networks. These boxes provide a safe and organized environment for splicing, distributing, and connecting fiber optic cables. SMC fiber optic distribution boxes are widely used in telecommunications, data centers, CATV networks, and other industries that require reliable and high-speed data transmission.

SMC fiber optic distribution boxes are designed to withstand harsh outdoor environments and provide excellent protection for fiber optic cables and equipment. The boxes are made of high-strength SMC (Sheet Molding Compound) material, which is resistant to corrosion, impact, and UV radiation. The SMC material also provides good insulation and thermal stability, preventing condensation and maintaining a stable temperature inside the box.

The box doors of SMC fiber optic distribution boxes are equipped with special sealing mechanisms, waterproof locks, and three-point door latches, ensuring a secure and reliable seal against moisture and dust. The boxes can be equipped with 12-core fusion splicing and distribution modules, allowing for easy and efficient cable management. They also support the installation of FC/SC fiber optic adapters for easy connection to fiber optic cables.

SMC fiber optic distribution boxes come in different sizes and capacities to meet the needs of different applications. The capacities range from 144 cores to 576 cores, with options for single-fiber and ribbon-fiber splicing. The boxes can be installed as floor-mounted or wall-mounted, depending on the installation requirements.
