We’ve reimagined the FOSC closure to help you stay ahead of your network demands. The new FOSC Premium Basket delivers up to 30% more storage and adjustable height settings for on-site flexibility—so you can expand capacity without replacing components. With features that simplify installation, secure cable management, and support emergency splicing, plus streamlined ordering and inventory processes, you’ll save time in the field and reduce operational complexities. The FOSC Premium Basket helps deliver the flexibility, speed and reliability needed to keep your network running—and your customers connected.

As fiber broadband networks scale, operators face a growing challenge: increasing fiber capacity and improving slack management within existing closure footprints—without adding material cost, increasing complexity, or requiring component replacement.

The FOSC® Closure Premium Basket was designed to directly address this challenge. Its field-adjustable, high-capacity design delivers up to 30% more slack storage capacity while enabling on-site expansion, improved fiber organization, and long-term adaptability. By eliminating the need for basket replacement during capacity growth, the solution supports faster installations, simplified inventory management, and more sustainable fiber infrastructure deployments.

The FOSC Premium Basket introduces a field-adjustable design with three height positions—standard, medium, and high—allowing technicians to expand fiber capacity during installation or future network growth without changing hardware. This flexibility provides operators with greater control and adaptability as network requirements evolve.

Larger basket sizes for A and B closures deliver up to 30% increased storage capacity, supporting both ribbon and loose tube fiber configurations. Field-adjustable, stackable retention tabs securely organize loose buffer tubes while enabling multi-layer fiber separation within a single basket—improving organization without increasing footprint.

Designed with real-world deployment conditions in mind, the FOSC Premium Basket enhances installation efficiency, fiber protection, and long-term serviceability through integrated features that simplify fiber management:

• Up to 30% increased slack storage capacity with larger baskets for A and B sizes.
• Field-adjustable height settings enable capacity expansion without basket replacement.
• Adjustable, stackable retention tabs support secure buffer tube management and multi-layer fiber organization.
• Multiple tie-down points improve cable routing and organization.
• Hook-and-loop fastener straps provide secure tray and cable retention.
• Improved basket-to-tower interface enhances retention while simplifying release.
• Integrated splice holder interface supports emergency splicing and installation of splice or splitter modules.

Collectively, these enhancements reduce handling during installation and maintenance, support faster and more consistent field deployment, and improve long-term network serviceability.

Sustainability is an inherent benefit of the FOSC Premium Basket design. Reduced material usage, compact packaging, and a long operational life cycle help minimize network waste. Most importantly, the ability to expand capacity without replacing the basket reduces material consumption over time and simplifies inventory management across large-scale deployment programs.

The FOSC Premium Basket delivers meaningful, field-driven innovation for fiber broadband networks. By increasing capacity, improving fiber organization, and enabling on-site adaptability within existing closure footprints, it helps operators deploy and maintain scalable fiber infrastructure more efficiently—without increasing complexity or operational burden.
