Belden Inc. TFSLG012RS5N OS2 12-fiber Pvc Riser Cable

Product Description

The BELDEN INC. TFSLG012RS5N is an OS2 single-mode, 12-fiber PVC riser-rated fiber optic cable designed for structured cabling installations in commercial and industrial environments. OS2 single-mode fiber supports long-distance, high-bandwidth data transmission, making it the standard choice for backbone runs, inter-building links, and campus network infrastructure. The PVC outer jacket is rated for riser (vertical) installation between floors. Licensed low-voltage and data cabling contractors are the primary installers of this cable type.

This cable is suited for riser-rated vertical pathways in multi-story commercial buildings, data centers, and campus environments where OS2 single-mode performance is required. It is a multi-fiber, tight-buffered or loose-tube construction intended for indoor backbone applications. The 12-fiber count supports structured cabling designs that require moderate fiber density within a single cable run.

Key Features

• OS2 single-mode fiber for long-distance, high-bandwidth transmission
• 12-fiber count for moderate-density backbone installations
• PVC jacket rated for riser (vertical between floors) installation
• OFCR designation meets riser fire rating requirements for indoor vertical runs
• Suitable for commercial structured cabling backbone applications

Compatibility

Designed as an OEM-style riser-rated OS2 single-mode fiber optic cable for use in commercial structured cabling backbone systems requiring a 12-fiber, PVC riser configuration.

Installation Notes

Installation should be performed by a licensed low-voltage or data cabling contractor familiar with TIA-568 and NFPA 70 (NEC) Article 770 requirements for optical fiber riser cables. Power down any active network equipment connected to the fiber path before terminating or splicing. Riser-rated cable must be routed through listed riser pathways and may not be substituted for plenum-rated cable in air-handling spaces. Observe minimum bend radius guidelines during pulling and final dressing to avoid signal degradation.
