High-Density Fiber Optic Closure for Demanding Network Environments
Telhua's FDM1-FO Fiber Optic Closure provides a robust, scalable solution for protecting and organizing fiber optic splices in aerial, underground, and direct burial applications. Engineered for maximum port density and long-term reliability, this closure addresses critical B2B challenges including space constraints, installation efficiency, and network uptime.
Addressing Core B2B Infrastructure Pain Points
Network operators and contractors require closures that minimize footprint while maximizing capacity. The FDM1-FO is designed with this balance in mind:
- Optimized Density: Accommodates high fiber counts in a compact form factor, reducing cabinet space requirements and total cost of deployment.
- Enhanced Reliability: Features a multi-layer sealing system (gel, gasket, and heat-shrink) that exceeds industry standards for waterproofing and dust protection, ensuring signal integrity in harsh environments.
- Rapid Deployment: Modular internal tray design and tool-less access panels enable faster splicing and maintenance, cutting labor costs and service restoration time.
Telhua Engineer's Tip: Managing Bending Radius in High-Density Configurations
When maximizing port density, maintain fiber bend radius above 30mm within the closure. Use our pre-formed radius limiters on splice trays to prevent microbending attenuation, which can degrade signal quality over long distances. This is critical for maintaining performance in 10G/40G/100G applications where even minor signal loss impacts network margins.
