Belden Inc. TRSLD144NSUN OS2 144-fiber Trunk Cable

Product Description

The BELDEN INC. TRSLD144NSUN is a 144-fiber OS2 single-mode trunk cable engineered for high-density fiber optic network infrastructure. OS2 single-mode fiber supports long-distance, low-loss signal transmission, making this trunk assembly a fit for backbone runs in commercial buildings, campus networks, and data center interconnects. The 144-fiber count accommodates large-scale connectivity demands in a single cable run, reducing pathway congestion and simplifying termination planning. Licensed network technicians and low-voltage cabling contractors are the primary installers of this product.

This trunk cable is suited for outdoor or indoor-outdoor routing scenarios where a high-count single-mode solution is required. Typical applications include inter-building campus runs, main distribution frame to intermediate distribution frame backbone links, and large-scale data center structured cabling projects. The OS2 fiber classification aligns with ITU-T G.652.D performance standards, supporting wavelengths at 1310 nanometers and 1550 nanometers for both short- and long-haul applications.

Key Features

• 144-fiber count supports high-density backbone and trunk cabling installations
• OS2 single-mode fiber for low-loss, long-distance signal transmission
• Multi-loose-tube construction for organized fiber management and strain relief
• Outdoor-rated construction suitable for direct burial or conduit routing between buildings
• Single unit per each sold, allowing flexible procurement for project-specific lengths

Compatibility

Designed as an OEM-style trunk cable compatible with standard OS2 single-mode fiber optic connector systems and high-density fiber distribution and termination enclosures used in commercial and enterprise network infrastructure.

Installation Notes

Installation should be performed by a qualified low-voltage cabling contractor or licensed network technician familiar with fiber optic handling practices. Follow TIA-568 and applicable local codes for fiber routing, bend radius minimums, and enclosure termination. Power down active network equipment before connecting or disconnecting fiber links. Avoid kinking or exceeding the minimum bend radius during pulling and routing to prevent signal degradation or fiber breakage.
