Indoor/Outdoor Interlocking Armored Trunk Assemblies
iFiber Optix's Indoor/Outdoor Interlocking Armored Trunk Assemblies are engineered to deliver robust, flexible fiber optic connectivity across diverse environments — eliminating the need for costly cable transitions between indoor and outdoor sections. With interlocking aluminum armor, UV and water-resistant jacketing, and pre-terminated MTP® connectors, these assemblies provide the enhanced protection and plug-and-play performance that modern data centers, enterprise networks, and telecom infrastructure demand.
Available in both Singlemode (OS2) and Multimode (OM3/OM4/OM5) fiber types with configurations up to 864 fibers, our Indoor/Outdoor Interlocking Armored Trunk Assemblies are factory pre-terminated and 100% optically tested before shipment — ready to deploy the moment they arrive on site.
Indoor/Outdoor Interlocking Armored Trunk Assembly
Available in singlemode OS2 and multimode OM3/OM4/OM5, these assemblies combine interlocking aluminum armor with UV/water-resistant jacketing for seamless indoor-to-outdoor transitions. Factory pre-terminated and 100% tested — supporting fiber counts up to 864 with MTP®/MPO connectivity.
Key Features
- Interlocking Aluminum Armor The interlocking aluminum armor offers superior mechanical protection against physical impacts and environmental hazards — eliminating the need for additional conduit in many installations. Despite its robust protection, the armor maintains flexibility and a lightweight profile, facilitating easier installation and handling in confined pathways and conduit runs.
- Indoor/Outdoor Versatility Equipped with a UV-resistant outer jacket and water-blocking aramid yarn strength members, these assemblies perform reliably in both indoor and outdoor environments. Their dual-rated construction eliminates the need for costly transitions between indoor and outdoor cable types — simplifying network design and reducing installation time and material cost.
- High-Fiber-Count Configurations Available in configurations up to 864 fibers to support the high-density requirements of modern data centers and enterprise networks. The compact armored design reduces overall cable diameter compared to multiple lower-fiber-count trunks, minimizing space requirements in pathways, conduits, and cable trays.
- Pre-Terminated MTP® Connectors Factory-terminated MTP® connectors ensure precision-quality terminations that reduce insertion loss and improve overall network performance. Pre-terminated assemblies enable plug-and-play deployment — minimizing downtime, reducing labor costs, and eliminating the risk of field termination errors.
