SZS-43/185/20 72F – Modular Fiber Optic Distribution Cabinet with Cable Storage for Splice Closure

The SZS-43/185/20 72F is a modular outdoor fiber optic distribution cabinet designed for FTTH networks and telecommunications infrastructure requiring high subscriber capacity. Its construction is optimized for efficient fiber distribution, cable management, and secure storage of excess feeder and subscriber cables together with a splice closure.

The cabinet is intended for direct ground installation by burying approximately 600 mm (24 in) below ground level, ensuring excellent stability and reliable protection of the fiber optic infrastructure. The enclosure is manufactured from 1 mm Magnelis® steel sheet, providing outstanding corrosion resistance and long-term durability in demanding outdoor environments. The exterior is finished with a RAL 7035 light grey powder coating, the standard color for telecommunications infrastructure.

Inside the cabinet is a removable fiber optic patch panel with a 72-fiber (72F) distribution field, supporting up to 36 SC Duplex adapters. This configuration allows connection of a large number of subscribers while ensuring convenient management of fiber terminations within a single distribution point.

The cabinet features 10 linear cable ports, enabling connection of feeder cables and installation of optical splitters within the access network. Its well-designed internal layout provides ample space for routing fiber optic cables and organizing fiber slack.

A key feature is the separate upper storage compartment designed for excess feeder and subscriber cable, secured with a weatherproof locking mechanism. This dedicated compartment allows safe storage of spare cable while providing easy access during installation, maintenance, and future network expansion.

The lower section of the enclosure incorporates a sealed multi-entry cable gland, allowing several cables to enter simultaneously while maintaining a high level of environmental protection. In addition, the cabinet is equipped with three feeder cable retention clamps, ensuring secure cable fixation and proper routing.

The enclosure complies with IP65 ingress protection and IK10 mechanical impact resistance, providing reliable protection against dust, moisture, and mechanical damage. Its robust construction, large fiber capacity, and practical cable management features make the SZS-43/185/20 72F an ideal solution for network operators deploying and expanding modern fiber optic access networks.
