Belden TT3LG012HNNN OM3 Multimode Fiber Patch Cable 12F Lszh

Product Description

The Belden TT3LG012HNNN is a 12-fiber OM3 multimode fiber optic patch cable designed for structured cabling installations in commercial and industrial environments. The cable features a Low Smoke Zero Halogen (LSZH) jacket and meets OFNG (Optical Fiber Nonconductive General) requirements, making it suitable for use in plenum-adjacent and general-purpose cable pathways where low-toxicity smoke output is required. This type of cable carries high-bandwidth optical signals between switches, patch panels, and active equipment. It is typically installed by licensed low-voltage or structured cabling technicians.

OM3 multimode fiber is rated for 10 Gigabit Ethernet applications and is commonly deployed in data centers, server rooms, and enterprise backbone runs. The 12-fiber count supports multiple simultaneous channels within a single cable assembly, reducing conduit congestion in high-density installations. The LSZH jacket makes this cable appropriate for buildings or projects governed by fire safety standards that restrict halogenated materials in occupied spaces.

Key Features

• OM3 multimode fiber core supports 10 Gigabit and higher bandwidth applications
• 12-fiber count enables high-density multi-channel deployments in a single run
• LSZH jacket reduces toxic smoke and halogen gas emission in the event of fire
• OFNG-rated construction suitable for general-purpose cable routing
• Sold as a single assembly (unit of measure: each)

Compatibility

Designed as an OEM-style replacement or direct-use patch cable for OM3 multimode fiber optic systems requiring a 12-fiber LSZH-jacketed assembly in general-purpose routing environments.

Installation Notes

Installation should be performed by a qualified low-voltage or structured cabling technician in accordance with applicable codes including TIA-568 and local fire and building codes. Disable active equipment and ensure optical ports are shuttered or powered down before connecting or disconnecting fiber assemblies. Avoid exceeding the cable minimum bend radius during routing to prevent signal loss or fiber damage. Do not apply pulling tension beyond the cable assembly rating and protect connectors with dust caps when not in use.
