NT1331_New-style Butterfly-type Fiber Optic Drop Cable Clamp
Item Description
The FTTH drop cable clamp from NEATEL is an essential component for effective cable management in fiber optic distribution networks. Designed to securely hold round optical cables, this clamp can accommodate spans of up to 70 meters, it providing a reliable and efficient solution for various installation scenarios. This one-piece thermoplastic clamp consists of a closed conical-shaped body, a round wedge with integrated lanyard and an opening bail. Thanks to its ruggedly engineered bail, the NEATEL NT1331 New-style Butterfly-type Fiber Optic Drop Cable Clamp is to be secured directly on pole fittings, with open or closed eye, or on pole hardware with Ø 10mm minimum. It also designed for round fibre optic cables with Ø 2.5 – 5 mm.
Features and Applications

What is a drop cable clamp?

A drop wire clamp is a mechanical fastening device designed to anchor and support aerial drop cables. It holds the cable firmly in place and transfers the cable's tension to the supporting hardware (like a pole hook or bracket), preventing stress from reaching the cable itself.

Where are drop wire clamps used?

These clamps are used in various overhead networks, most commonly in:

• FTTH (Fiber to the Home) networks to connect the distribution line to a subscriber's building.
• Telecommunications networks for aerial telephone and communication cables.
• CATV networks to secure coaxial drop cables.
