Ø4-6mm Drop Clamp for Round Fiber Optic Cable – Spring Optical
The Spring Optical Drop Clamp for Round Fiber Optic Cable is designed for FTTH aerial round drop cables with diameters ranging from 4 to 6 mm. Reliable dead-ending, excellent cable retention, and long-term durability in fibre access networks, make this product suitable for today's air droppers in the deployment of FTTH even in the most difficult terrains and standard pole installations.
Key Performance & Compliance of Drop Clamp for Round Fiber Optic Cable
Fully compliant to standard in terms of performance:
NF EN C-20-540 Climatic ageing test
ORANGE CCF/DI/BUBL Technical tensile test (2010/05)
ORANGE CCF/BI/BUBL & NF EN 50289-3-13 Vibration resistance and insertion loss less than 0.2 dB
Maximum Tension Load: 1200 N (for reference cables)
Installation Guidelines for Round Fiber Optic Cables
In particular, the Spring Optical Drop Clamp for Round Fiber Optic Cable can be used for:
Mounting on end poles and on poles with angles exceeding 25° (road crossings require cable stops on each side)
Unbalanced spans (for example 40 m span followed by 30 m)
Rugged terrain (downhill or on a slope)
Mounting on every fifth pole or every pole if double-anchor installations are required
Installation Advantages of Drop Clamp for Round Fiber Optic Cable
Single-piece, cost-effective design
Quick, simple and toolless installation
Effective cable grip with capstan effect sufficient to hold fibre without deformation (minimum 3 turns)
Suitable for pole hardware different from the pole's circumference (Ø ≥ 10 mm, eye or pigtails)
Design Features of Drop Clamp for Round Fiber Optic Cable
Mandrel-shaped body allows self-tightening and roll-up of the cable (minimum 3 turns)
Opening bail enables direct mounting to a pole fitting
Made from UV-resistant thermoplastic offering at least 25 years of service lifespan
Compatible with any open or closed hardware type (Ø ≥ 10 mm)
