Belden Inc. TRSLD048NRUN OS2 48-fiber Trunk Cable

Product Description

The BELDEN INC. TRSLD048NRUN is an OS2 single-mode fiber optic trunk cable rated for 48 fibers. OS2 single-mode fiber supports long-distance, high-bandwidth transmission with low signal attenuation, making it the standard choice for backbone and inter-building runs in enterprise, data center, and industrial network infrastructure. This trunk assembly ships ready to pull, reducing field termination time and the risk of installation error. It is typically installed by licensed low-voltage technicians and structured cabling contractors.

This trunk cable is suited for pre-terminated backbone applications in commercial and data center environments. Its 48-fiber count supports high-density distribution frames, main distribution areas (MDA), and horizontal distribution areas (HDA). OS2 single-mode construction is appropriate for runs exceeding the practical limits of multimode fiber, typically over 300 meters, where laser-optimized precision is required. Contractors specify this cable for new builds and infrastructure upgrades where future bandwidth scalability is a priority.

Key Features

• OS2 single-mode fiber construction for long-distance, high-bandwidth backbone runs
• 48-fiber count supports high-density distribution and aggregation points
• Pre-terminated trunk format reduces field labor and splice errors
• Suited for data center backbone, inter-building, and campus network applications
• Sold as a single unit (EA) per the manufacturer unit of measure

Compatibility

Designed as an OEM-style trunk cable for use with OS2 single-mode fiber optic distribution and patch panel systems in structured cabling installations.

Installation Notes

Installation should be performed by a qualified low-voltage or structured cabling technician in accordance with ANSI/TIA-568 standards. Power down or deactivate all active optical equipment connected to the run before handling fiber connectors. Avoid bending the cable below its minimum bend radius during pull-through to prevent fiber damage or signal degradation. Inspect all connector end-faces with a fiber inspection scope before mating.
