Belden Inc. TUSC0012RR2N OS2 12-fiber Plenum Fiber Optic Cable

Product Description

The BELDEN INC. TUSC0012RR2N is an OS2 single-mode, 12-fiber tight-buffered optical cable with a CPE (composite polyethylene) outer jacket and OFNR (Optical Fiber Nonconductive Riser) rating. Designed for outdoor and riser-rated installations, this cable supports long-distance, low-attenuation data transmission in commercial and industrial fiber optic networks. Licensed low-voltage and data cabling contractors typically specify OS2 tight-buffered construction for backbone runs where tight bend radius management and individual fiber access are priorities. The TUSC0012RR2N is sold per unit (EA), with one cable assembly per unit.

This cable is suited for outdoor-to-indoor transition runs, riser shafts, and campus backbone applications where a riser fire rating is required. OS2 single-mode fiber supports high-bandwidth, long-haul links typically found in enterprise, institutional, and industrial facilities. The tight-buffered construction makes individual fiber termination straightforward without the need for fanout kits, which is an advantage in structured cabling environments with frequent field terminations.

Key Features

• OS2 single-mode fiber for low-attenuation, long-distance optical transmission
• 12-fiber count supports multi-drop backbone and high-density riser runs
• OFNR riser rating meets fire code requirements for vertical riser shaft installations
• Tight-buffered construction allows direct field termination without fanout hardware
• CPE outer jacket provides resistance to outdoor environmental exposure

Compatibility

Designed as an OEM-style riser-rated OS2 single-mode fiber optic cable suitable for outdoor-rated riser backbone applications in commercial structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or data communications cabling contractor in accordance with NEC Article 770 governing optical fiber cables. De-energize any adjacent electrical systems before pulling cable through shared pathways or conduit. Observe the cable manufacturer minimum bend radius during pulling and routing to avoid fiber stress or damage. Outdoor segments exposed to UV or direct weather should be transitioned to an indoor-rated cable at the building entry point per applicable fire and building codes.
