Skip to content In the telecommunication trade, feeder and distribution cables work together to form a comprehensive network. Feeder cables act as high-capacity, long-distance conduits connecting central points to local nodes, while distribution cables branch out from these nodes to provide services to end-users. Both are essential for the functionality and efficiency of modern telecommunication networks.
Fiber optic cables, designed for efficient signal transmission, feature a core structure protected by robust layers and strength elements. They ensure reliable communication with compact, flexible designs for space efficiency and safety through flame-retardant materials, catering to diverse installation environments.
Multiple cores within the cable.
Transmits optical signals efficiently.
A thin, protective tubing around the fiber core.
Provides extra protection for the core, allowing for expansion and contraction with temperature changes.
A wrap or gel around the core.
Prevents moisture and gas intrusion.
Metal core, often steel or glass fiber.
Provides mechanical strength.
A thick, gel-like substance surrounding the reinforcement.
Adds additional protection and insulation to the cable.
Metal or other durable materials.
Protects from physical damage; suitable for various installations.
Resistant chemical material.
Shields against environmental stress and damage
A cord placed under the outer sheath.
Facilitates easy removal of the outer sheath during installation.
Colored marking on the outer sheath.
Provides cable identification and differentiation.
Fiber Core is the heart of the fiber optic cable where the network signal is transmitted. The core is typically made of glass (silica), It has a higher transmission capability and is mostly used in telecommunications. the types are single-mode G.652, G.655, G.657, Multi-mode OM2, OM3, OM4 and more. The strength member to withstand environmental stresses like pulling, bending, and crushing. In different cables, can be made of materials like aramid yarns (e.g., Kevlar), steel wires, and fibreglass. The armour layer is to protect the cable from mechanical damage such as cuts, abrasions, and crush loads that could occur during installation or service. The outer jacket, or sheath, is the outermost layer of the cable and is responsible for environmental protection. Materials used for the jacket include PVC (Polyvinyl Chloride), LSZH (Low Smoke Zero Halogen), polyethylene (PE), and polyurethane (PU). Each material serves different environments.
The production process of a fiber distribution box involves designing the enclosure for environmental resilience, molding the casing from durable materials, assembling internal components like splice trays and splitter cassettes, installing cable management systems, and incorporating security features like lockable covers. Quality checks ensure functionality and protection against environmental factors before distribution.
