Belden Inc. TTSLD012LTNN OS2 12-fiber Lszh Cable

Product Description

The BELDEN INC. TTSLD012LTNN is a tight-tube, multi-fiber OS2 single-mode fiber optic cable with a low-smoke zero-halogen (LSZH) jacket. It is rated for 12 fibers and is designed for structured cabling installations where fire safety and smoke toxicity are primary concerns. The LSZH jacket reduces toxic gas and smoke emission in the event of a fire, making this cable suitable for installations in plenum-adjacent or enclosed environments where local codes require it. Fiber optic technicians and low-voltage cabling contractors install this type of cable in commercial data, telecom, and campus backbone runs.

This cable is suited for indoor and indoor-outdoor fiber optic backbone applications in commercial and institutional buildings. The OS2 single-mode designation means it is optimized for long-distance, high-bandwidth signal transmission typically found in enterprise LAN backups, inter-building runs, and data center uplinks. The tight-tube construction protects individual fibers during installation and routine handling, making it a practical choice for conduit pulls and tray routing in structured cabling projects.

Key Features

• OS2 single-mode fiber optimized for long-distance, high-bandwidth transmission
• 12-fiber count supports multi-channel backbone and uplink configurations
• LSZH jacket minimizes smoke and toxic gas output in fire conditions
• Tight-tube construction provides mechanical protection for individual fibers
• Suitable for conduit, cable tray, and indoor backbone installations

Compatibility

Designed as an OEM-style replacement or new-installation fiber optic cable for OS2 single-mode structured cabling systems requiring a 12-fiber LSZH tight-tube construction.

Installation Notes

Installation should be performed by a qualified fiber optic technician or licensed low-voltage cabling contractor familiar with TIA-568 and local fire code requirements. De-energize or power down active equipment at both termination points before splicing or connectorizing. Observe the manufacturer minimum bend radius during pulls to avoid microbending losses. Verify that the LSZH jacket rating meets the applicable local building or fire code before installation in enclosed or occupied spaces.
