Fiber Optic Cable Fitting Bolts

Fiber optic cable fitting bolts, including pigtail and poleline bolts, are high-strength, corrosion-resistant fasteners used to secure and tension aerial fiber optic cables on utility poles and other structures.

Types of Fiber Optic Cable Fitting Bolts

Pigtail Bolts (Pigtail Eyebolts): These bolts are designed to tension overhead fiber optic cables using tension or suspension clamps. They often feature an open or closed loop wire bail and are made of high-strength galvanized steel to withstand environmental conditions such as rain, snow, dust, and sun exposure, ensuring long-term durability and mechanical strength for supporting cable weight and tension . Poleline Bolts: Typically made of galvanized or stainless steel, poleline bolts are used to attach utility poles, cross arms, insulators, and other electrical or fiber optic equipment. They are corrosion-resistant and designed for high mechanical strength, ensuring the stability and safety of mounted structures .

Materials and Coatings

Fiber optic fitting bolts are usually made from high-strength steel and coated with hot-dip galvanization to resist corrosion and environmental wear. This coating is critical for outdoor installations where exposure to moisture, UV radiation, and temperature fluctuations is common .

Applications

• Aerial Fiber Optic Cables: Bolts secure cables to poles and towers, often in combination with tension clamps or suspension hardware .
• Utility Poles and Cross Arms: Poleline bolts attach structural components and insulators, providing a stable mounting point for fiber optic lines .
• Preformed Suspension Hardware: Some bolts are used with preformed suspension kits to fix conductors or cables in place, reducing axial load and ensuring uniform radial compression .

Installation Features

• Ease of Installation: Pigtail bolts often have a head design that allows rotation and fixing by hand, speeding up installation and maintenance .
• High Mechanical Strength: Designed to handle the weight and tension of fiber optic cables, ensuring secure and reliable support .
• Environmental Resistance: Galvanized coatings and durable steel construction protect against corrosion, UV exposure, and extreme weather conditions .

Related Accessories

Fiber optic cable fitting bolts are commonly used alongside:

• Tension Clamps: For securing cables under tension.
• Suspension Devices: To hang cables from poles or towers.
• Dead-End Clamps: For terminating cables in low-tension environments . These bolts and accessories are essential for maintaining the integrity, safety, and longevity of fiber optic networks, particularly in outdoor and aerial installations.
