Belden TUSD9012RN2N OS2 12-fiber Distribution Cable

Product Description

The Belden TUSD9012RN2N is a tight-buffered, OS2 single-mode indoor distribution fiber optic cable rated for plenum (OFNR) installations. Designed with a 12-fiber count and CPE outer jacket, this cable delivers reliable low-loss signal transmission in structured cabling systems. The OS2 designation indicates compliance with single-mode fiber standards optimized for long-distance, high-bandwidth data runs. Licensed low-voltage and communications cabling contractors install this type of cable in commercial and institutional environments where fire code requires a plenum-rated pathway.

This cable is suited for indoor backbone and horizontal distribution runs in commercial buildings, data centers, campus environments, and healthcare or education facilities. The plenum OFNR rating makes it appropriate for installation in air-handling spaces and above-ceiling plenum plenums without conduit where permitted by local code. The tight-buffered construction simplifies field termination and makes it compatible with standard indoor fiber connector installations.

Key Features

• OS2 single-mode fiber for long-distance, low-attenuation signal transmission
• 12-fiber count for mid-density backbone and distribution applications
• OFNR (plenum) jacket rating meets fire code requirements for air-handling spaces
• Tight-buffered construction simplifies termination without breakout kits
• CPE outer jacket provides chemical and environmental resistance for indoor runs

Compatibility

Designed as an OEM-style indoor distribution fiber cable compatible with standard OS2 single-mode fiber termination hardware and patch panels used in structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 structured cabling standards and local fire codes. De-energize any active equipment in the pathway before pulling cable. Observe minimum bend radius requirements for the cable diameter during routing to avoid fiber stress or breakage. Verify local authority having jurisdiction (AHJ) acceptance of OFNR-rated cable in the intended plenum space before installation.
