What Is a Fiber Optic Dead End Clamp?
A Fiber Optic Dead End Clamp secures the end of an aerial fiber cable by providing strong mechanical anchoring without damaging the cable sheath.
Fiber optic dead end clamps—also known as optical cable anchoring clamps, ADSS dead-end clamps, or FTTH drop wire tension clamps—are installed on poles where a cable line terminates or changes direction. They use wedges or tapered bodies to grip the cable tightly, ensuring mechanical strength, anti-slip support, and long-term load distribution.
These clamps are widely used in FTTx networks, ADSS installations, and overhead telecom cabling.
Types of Fiber Optic Dead End Clamps
Different designs support different cable sizes, structures, and installation environments.
Common types include:
1. ADSS Dead End Clamp (Anchor Clamp for ADSS Cable)
Designed for high-tension ADSS aerial fiber routes
UV-resistant polymer + galvanized steel bail
Suitable for cable ranges: 4–20 mm
2. FTTH Drop Cable Dead End Clamp
Ideal for low-tension 2–4 mm flat or figure-8 drop cables
Tool-free installation
Widely used in last-mile FTTx connections
3. Wedge Type Optical Cable Tension Clamp
Automatic wedge-lock mechanism
Ensures constant grip under varying load conditions
Used for medium-span aerial routing
Key Features and Advantages
Strong grip, anti-slip performance, corrosion resistance, and quick installation make dead end clamps essential for stable fiber networks.
High Mechanical Strength
Made from weather-resistant polymer and stainless or galvanized hardware, these clamps secure cables in harsh environments including coastal zones and high-temperature regions.
Non-Damaging Cable Grip
Internal grooves ensure tight grip without crushing or damaging the cable jacket.
Easy, Tool-Free Installation
Wedge-action mechanisms reduce installation time, ideal for fast deployment in FTTH and ADSS projects.
Long-Term Outdoor Durability
UV resistance, anti-corrosion metals, and anti-aging materials ensure 20–30 years of service life.

Installation Guidelines for Fiber Optic Dead End Clamps
Proper placement and tension control ensure safe and stable cable anchoring.
Choose the proper clamp according to cable diameter.
Place the cable inside the wedges or grooves.
Pull the clamp’s bail over the hook or bracket on the pole.
Apply tension to seat the wedges automatically.
Confirm grip strength and stability.
Correct installation ensures long-term performance in windy or high-load environments.
FAQ: Fiber Optic Dead End Clamps
1. What cable sizes do dead end clamps support?
Most clamps support ADSS cables from 4–20 mm and FTTH drop cables from 2–4 mm, depending on the model.
2. Can I use one clamp for all cable types?
No. Use an FTTH clamp for drop cables and an ADSS anchor clamp for medium/high-tension ADSS routes.
3. Do dead end clamps damage the cable?
High-quality clamps from Hunan Jiahome use smooth wedges that grip the cable without damaging the sheath.
4. Are these clamps suitable for coastal or high-UV regions?
Yes. UV-resistant polymer and anti-corrosion materials ensure stable performance in harsh climates.
5. Do they require tools for installation?
Most FTTH and ADSS clamps use a tool-free wedge locking system for easy installation.
