Outdoor Interlocking Armored Multi-Fiber Trunk Assembly
Available in singlemode OS2 and multimode OM3/OM4/OM5, these assemblies combine interlocking aluminum armor with UV-resistant, gel-free waterblocking construction for maximum outdoor durability. Factory pre-terminated and 100% tested — supporting fiber counts up to 864 with MTP®/MPO connectivity and Corning SMF-28® Ultra fiber compatibility.
Key Features
- Interlocking Aluminum Armor Heavy-duty interlocking aluminum armor shields fibers from crushing, impact, and rodent damage — eliminating the need for rigid conduit in many outdoor installations. The highly flexible armored design allows easy routing through tight spaces, conduit bends, and challenging installation pathways.
- Outdoor-Rated Construction UV-resistant, water-blocking outer jacket ensures durability and consistent performance in harsh weather conditions. Flame-retardant materials meet safety requirements for outdoor and enclosed environments, and the dual-rated construction supports seamless indoor-to-outdoor transitions without additional splicing.
- High-Density Fiber Configurations Available in singlemode and multimode (OM3, OM4, OM5, and OS2) fiber types supporting up to 864 fibers for high-bandwidth outdoor applications. Utilizes Corning SMF-28® Ultra fiber for low-loss, high-performance networking across the full range of fiber count configurations.
- Pre-Terminated MTP®/MPO Connectors Factory-terminated for precision alignment and minimal insertion loss — compatible with Corning MTP® solutions for seamless integration into existing networks. Plug-and-play deployment reduces installation time, labor costs, and the risk of field termination errors in outdoor environments.
- Gel-Free Waterblocking Gel-free waterblocking technology eliminates the mess of traditional gel-filled cables — ensuring faster fiber preparation, easier termination, and superior moisture protection for enhanced longevity in outdoor conduit, aerial, underground duct, and direct-burial applications.
