Belden Inc. TTSLD012LRNN OS2 12-fiber Lszh Fiber Cable

Product Description

The BELDEN INC. TTSLD012LRNN is an OS2 singlemode fiber optic cable rated for 12 fibers and jacketed with a Low Smoke Zero Halogen (LSZH) compound. It carries an OFNR (Optical Fiber Nonconductive Riser) rating, making it suitable for riser-rated building pathways where low-smoke, halogen-free materials are required by code. This type of cable is specified by low-voltage installers, data communications contractors, and licensed electricians working in commercial or institutional environments where air-handling spaces and fire-code compliance drive material selection.

OS2 singlemode fiber is standard in long-distance, high-bandwidth backbone runs within commercial buildings, campuses, and data centers. The 12-fiber count accommodates structured cabling installations that require spare capacity for future growth or redundant links. The LSZH jacket reduces toxic gas and smoke emission in the event of fire, a requirement enforced in many European standards and increasingly adopted in North American commercial construction specifications.

Key Features

• OS2 singlemode fiber classification for long-distance, low-attenuation data transmission
• 12-fiber count supports backbone and inter-equipment runs with room for spare fibers
• LSZH jacket compound limits smoke and halogen gas emission under fire conditions
• OFNR riser rating permits installation in vertical shaft and riser pathways per applicable codes
• Sold as a single unit (EA) per manufacturer packaging

Compatibility

Designed as an OEM-style singlemode OS2 fiber optic cable for use with standard SC, LC, ST, and FC connector terminations in riser-rated commercial structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic contractor familiar with ANSI/TIA-568 structured cabling standards and local building codes governing riser pathways. Observe minimum bend radius requirements during pulling and routing to avoid fiber stress or damage. All terminations should be completed with appropriate fiber-optic tooling and tested with an OTDR or optical power meter after installation. Do not exceed the cable's rated pulling tension during conduit pulls.
