Aerial Optical Cable Clip Type

Aerial optical cable clips, also known as drop wire clamps, secure and support fiber optic cables on poles, walls, or messenger wires, ensuring stable and safe aerial installations.

Overview

Aerial optical cable clips are essential for fiber-to-the-home (FTTH), FTTx, and telecom networks, providing mechanical support and preventing cable sagging or damage. They are designed to hold fiber optic drop cables in place while withstanding environmental stress, UV exposure, and mechanical tension .

Common Types

1. Fiber Drop Clamps (Dead End Clamps)
   • Made from stainless steel (AISI 304) for durability and corrosion resistance .
   • Ideal for pole, building, or mid-span installations.
   • Can support one to six drop cables and handle mechanical tension exceeding the cable's yield strength .
2. S-Type Drop Wire Clamps
   • Specifically designed for flat drop cables like GJYXCH used in FTTH networks .
   • Provides a secure grip without bending or damaging the cable.
   • Suitable for aerial, wall-mounted, or pole-mounted routes.
3. Rubber Pad Insulated Clamps
   • Include a rubber or plastic lining to protect the cable from abrasion .
   • Often used on power towers, utility poles, or tunnels.
   • Compatible with round or flat fiber cables.
4. FTTH Cable Drop Wire Clamps
   • Available in stainless steel or plastic/nylon depending on durability and cost requirements .
   • Designed for outdoor environments, resistant to UV, humidity, and temperature variations.
   • Tensile strength ranges from 500 N to over 1,000 N, depending on the model .

Installation Considerations

• Ensure the clamp groove matches the cable size to avoid over-tightening or damage .
• Mounting can be pole-mounted, wall-mounted, or attached to messenger wires.
• Select clamps based on cable type (flat vs round), environmental conditions, and mechanical load requirements .
• Proper installation ensures long-term stability, prevents sagging, and maintains network reliability.

Summary

Choosing the right aerial optical cable clip depends on cable geometry, installation environment, and mechanical requirements. Stainless steel clamps are preferred for durability, while plastic or nylon options may be suitable for cost-effective or indoor applications. S-type and dead-end clamps are widely used in FTTH and aerial fiber networks to ensure secure, safe, and long-lasting cable deployment .
