Belden Inc. TM1C0004MNAN OM1 4-fiber Lszh Ofnr Cable

Product Description

The BELDEN INC. TM1C0004MNAN is an OM1 multimode fiber optic cable rated for indoor riser (OFNR) installations with a Low Smoke Zero Halogen (LSZH) jacket. Designed for structured cabling and data network applications, this 4-fiber cable delivers reliable optical performance in environments where flame spread and toxic smoke emission are primary concerns. The OFNR rating meets National Electrical Code requirements for vertical riser runs between floors. Licensed low-voltage contractors and network cabling technicians install this cable in commercial and institutional buildings where LSZH compounds are specified by code or facility standard.

This cable is suited for horizontal and vertical indoor runs in commercial office buildings, data centers, healthcare facilities, and educational campuses where both fire safety and optical performance are required. The 4-fiber count makes it appropriate for small backbone segments, zone distribution, or workgroup connections where OM1 62.5-micron multimode fiber meets the bandwidth and distance requirements of the installed system.

Key Features

• OM1 multimode fiber type supports standard 62.5-micron core multimode optical performance
• LSZH jacket compound minimizes toxic smoke and halogen gas emission in the event of fire
• OFNR (Optical Fiber Nonconductive Riser) rating approved for riser installations per NEC Article 770
• 4-fiber configuration suitable for small backbone and zone-distribution cabling runs
• Indoor-rated construction engineered for plenum-free, riser-pathway deployments

Compatibility

Designed as an OEM-style riser fiber optic cable for indoor structured cabling systems requiring OM1 multimode fiber with an LSZH jacket and OFNR fire rating.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 and NEC Article 770 requirements. De-energize any adjacent electrical systems and follow building fire-stop procedures when penetrating rated assemblies. Observe the cable minimum bend radius and maximum pull tension during installation to avoid micro-bending losses. Terminate with appropriate OM1-rated connectors and test with an optical loss test set per TIA-526 standards.
