Description
The FAB-OFC-M4AX-RI Fiber Joint Closure is engineered to provide reliable protection and organization for high-capacity optical fiber splicing in demanding outdoor telecommunications networks. Designed for aerial, pole-mounted, pipeline, wall-mounted, and direct-buried installations, it delivers dependable environmental sealing and long-term mechanical protection for backbone and distribution fiber cables.
Manufactured from high-strength polypropylene (PP) with UV-resistant and anti-aging additives, the enclosure withstands harsh environmental conditions while maintaining excellent structural integrity. Its single-ended dome design simplifies installation and maintenance, allowing repeated opening without requiring special tools. Heat-shrink cable sealing and a silicone rubber sealing ring provide dependable environmental protection against moisture and contaminants.
Supporting up to 672 fiber splices distributed across 12 splice trays, the FAB-OFC-M4AX-RI is well suited for high-density FTTH, FTTx, metropolitan, and backbone optical networks. The closure also incorporates robust mechanical performance, including resistance to tensile loads, vibration, impact, twisting, and bending, helping maintain optical performance under demanding field conditions.
As part of the Fibramérica portfolio, the FAB-OFC-M4AX-RI offers a dependable solution for network operators, contractors, and ISPs seeking durable fiber splice protection, simplified field maintenance, and scalable capacity for modern fiber optic deployments.
