Belden Inc. TTSLD144LRNN 144-fiber OS2 Lszh Ofnr Cable

Product Description

The BELDEN INC. TTSLD144LRNN is a tight-buffered, multimode OS2 144-fiber indoor fiber optic cable with a Low Smoke Zero Halogen (LSZH) jacket rated OFNR for riser applications. Designed for high-density structured cabling installations, this cable supports long-distance single-mode transmission in commercial and enterprise environments. The LSZH jacket reduces toxic smoke and halogen gas emissions during a fire event, making it the appropriate choice for occupied buildings, plenum-adjacent risers, and transit facilities where code compliance is mandatory. Licensed electricians and low-voltage cabling technicians are the primary installers of this product.

This cable is suited for indoor riser runs in commercial office buildings, data centers, healthcare facilities, and campus backbone infrastructure. Its 144-fiber count supports high-density patch and splice configurations at telecommunications rooms and main distribution frames. The OFNR rating qualifies it for vertical riser pathways between floors, and the LSZH jacket meets fire safety requirements in jurisdictions enforcing stricter emissions standards. It is sold and used as a single unit per reel.

Compatibility

Designed as an OEM-style indoor riser fiber optic cable for high-density OS2 single-mode backbone cabling systems in commercial and enterprise structured cabling environments.

Installation Notes

Installation should be performed by a licensed low-voltage cabling technician or licensed electrician in accordance with NEC Article 770 governing optical fiber cables. De-energize any adjacent electrical systems before beginning installation in shared pathways. Maintain minimum bend radius requirements throughout the run to avoid fiber damage. Do not exceed the cable's rated tensile load during pull installation.
