- Product Introduction
Fiber Optic Drop Cable Closure
GL-FDB-305 fiber Drop Cable Closure (FOSC) are used for distribution with signal splitting. They are suitable for straight-through or branch connections, distribution connections in optical systems, and the protection of cable and distribution pigtail connections.
Designed with a three-layer structure, they facilitate splitting and splicing. The middle panel rotates ≥180 degrees, making installation and maintenance easy. The middle panel of this drop cable closure is optiona Without it, the closure can function as a basic splice closure.

Features:
• Ambient temperature ranges from -40 to +65℃.
• The closure has a small volume, large capacity, and is convenient for maintenance.
• The closure casing is made of a quality engineering plastic, and has good performance for resisting acid, alkali, and salt erosion, as well as anti-aging properties. It features a smooth appearance and a reliable mechanical structure.
• The mechanical structure is reliable and provides resistance against harsh environments, intensive climate changes, and severe working conditions.
•The splice trays (FOST) inside the drop cable closure open like booklets. They provide adequate curvature radius and space for winding optical fiber to ensure a minimum winding curvature radius of 40 mm. Each optical cable and individual fiber can be operated individually.
•Suitable for a 2x1:8 sub-rack PLC splitter or for 2 pieces of tubed PLC splitter.
•Features include: Anti-UV protection, shock resistance, and waterproofing.
•Unique middle panel (≥180° opening) provides a clear area for splicing and distribution, reducing cable cross-connection.
•Suitable for uncut cables.

FAQ:
Q: How are cables sealed and secured within the drop cable closure?
A: The closure utilizes multiple cable entry ports with integrated mechanical seals/grommets designed for specific cable diameters to ensure a watertight and dustproof seal. Internal cable management or strain relief features secure the cables inside.
Q: Does the product come with mounting hardware?
A: It depends on customer's need. the drop fiber cable closure will include necessary mounting hardware such as brackets or straps for secure attachment to poles, walls, or aerial strands as customer required. Please refer to the packaging contents.
