Belden Inc. TTSLD144LTNN 144-fiber OS2 Lszh Cable

Product Description

The BELDEN INC. TTSLD144LTNN is a tight-tube, multi-fiber OS2 single-mode optical fiber cable rated for outdoor use with a Low Smoke Zero Halogen (LSZH) jacket. With 144 fibers in a tight-tube construction, this cable is built for high-density fiber runs where space and routing efficiency matter. The LSZH jacket reduces toxic smoke and halogen gas emissions in the event of a fire, making it appropriate for installations in occupied buildings, plenum-adjacent runs, or enclosed infrastructure where code or spec requirements call for reduced fire hazard materials. Licensed cabling contractors and low-voltage fiber installers are the typical trades handling this product.

This cable is suited for structured cabling infrastructure in commercial buildings, campus campuses, data centers, and industrial facilities that require OS2 single-mode performance. The tight-tube design supports both indoor and outdoor routing, including conduit-fed runs between buildings or floors. High fiber count makes it a practical choice for backbone cable runs where future capacity needs to be addressed in a single pull.

Key Features

• OS2 single-mode fiber for long-distance, low-attenuation transmission
• 144-fiber count in a tight-tube construction for high-density applications
• LSZH jacket reduces toxic smoke and halogen emissions during combustion
• Outdoor-rated construction suitable for conduit and protected exterior runs
• Tight-tube design simplifies termination and fiber management

Compatibility

Designed as an OEM-style replacement or new-installation fiber cable for high-density OS2 single-mode structured cabling systems. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation of this fiber cable should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 and applicable local codes. Always verify minimum bend radius requirements before routing through conduit or around corners, and avoid exceeding the cable's rated tensile load during pulls. Proper fiber-specific termination tools and cleaning equipment should be used at every connector point. Power down active equipment at the patch panel or switch before making or breaking live fiber connections.
