Belden Inc. TMSC0008MNAN OS2 8-fiber Lszh Ofnr Cable

Product Description

The BELDEN INC. TMSC0008MNAN is an OS2 single-mode fiber optic cable rated for 8-fiber construction with a Low Smoke Zero Halogen (LSZH) jacket and Optical Fiber Nonconductive Riser (OFNR) fire rating. OS2 single-mode fiber supports long-distance, high-bandwidth data transmission with low signal loss, making it a standard choice for backbone and riser runs in commercial and industrial network infrastructure. The LSZH jacket reduces toxic smoke and halogen gas emissions in confined spaces, which is a key requirement in many building codes for occupied facilities. Licensed low-voltage and fiber optic installers are the primary tradespeople handling this cable.

This cable is suited for riser-rated indoor installations where OS2 single-mode performance is required. Typical applications include inter-floor backbone runs, data center distribution segments, campus building interconnects, and telecom room-to-room links. The 8-fiber count supports multiple duplex channels within a single cable run, making it efficient for structured cabling projects that require scalable fiber capacity in a riser pathway.

Key Features

• OS2 single-mode fiber for long-distance, low-attenuation transmission
• 8-fiber construction supports multiple duplex data channels in one run
• LSZH jacket reduces toxic smoke and halogen gas output in fire events
• OFNR fire rating meets riser installation code requirements
• Sold as individual unit (EA), quantity per unit: 1

Compatibility

Designed as an OEM-style riser fiber optic cable for use in OS2 single-mode structured cabling systems requiring LSZH-jacketed, OFNR-rated cable.

Installation Notes

Installation should be performed by a licensed low-voltage or fiber optic technician familiar with TIA-568 and applicable local building codes. De-energize any adjacent powered infrastructure before pulling cable through shared pathways. Observe the cable's minimum bend radius and maximum pull tension ratings during installation to avoid microbend damage to the fiber. Fiber end-faces must be properly cleaved, polished, or factory-terminated and cleaned before mating to connectors or enclosures.
