The Telexc TX Series ADSS/OPGW Metal Junction Box is a heavy‑duty outdoor fiber optic splice enclosure designed for secure splicing and protection of ADSS (All‑Dielectric Self‑Supporting) and OPGW (Optical Ground Wire) cables. It is widely used in power transmission lines, telecom backbones, FTTX networks, CATV, and long‑distance optical communication systems.

Manufactured from high‑strength aluminum alloy, the enclosure delivers excellent mechanical strength, corrosion resistance, and long‑term reliability under high‑voltage electric field environments. The dome‑to‑base structure supports multiple splice trays with hinged access, allowing maintenance of any tray without disturbing others. Advanced sealing technology ensures IP65 protection against water, dust, vibration, UV exposure, and extreme temperatures.

The TX Series is suitable for tower mounting, pole mounting, wall installation, aerial deployment, duct installation, and direct burial, providing flexible solutions for diverse outdoor network scenarios.
