Corning® OM3 10G Multimode Fiber Optic Cable – 50/125µm, Simplex, Tight Buffer, LSZH, Indoor

Elevate your network infrastructure with genuine Corning® OM3 multimode fiber optic cable, engineered for superior performance in 10 Gigabit Ethernet applications up to 300 meters. This simplex cable features a robust 50/125µm core/cladding and a tight buffer construction for enhanced protection and easier termination. Its round, LSZH (Low Smoke Zero Halogen) jacket ensures safety in indoor environments by minimizing toxic and corrosive gas emissions during a fire, making it an ideal choice for data centers, enterprise backbones, and horizontal cabling.

Key Features:

• Genuine Corning® Fiber: Ensures industry-leading quality, reliability, and performance.
• OM3 Optimized Multimode Performance: Supports 10 Gigabit Ethernet (10GBASE-SR) up to 300 meters and 40/100 Gigabit Ethernet up to 100 meters.
• 50/125µm Core/Cladding: Standard multimode fiber dimensions for compatibility with common transceivers and equipment.
• Simplex Configuration: Single fiber strand, ideal for applications requiring one-way data transmission or paired for bi-directional links using separate transmit/receive paths.
• Tight Buffer Construction: Provides excellent fiber protection, easy stripping, and direct connectorization.
• LSZH (Low Smoke Zero Halogen) Jacket: Enhances safety in indoor installations by producing minimal smoke and no halogenated gases when exposed to fire. Complies with stringent fire safety regulations.
• Indoor Rated: Specifically designed for use within buildings, plenum, or riser spaces (verify specific rating if applicable, e.g., OFNR, OFNP – LSZH is often general indoor).
• Round Cable Design: Standard form factor for easy handling and installation in conduits and trays.

Benefits:

• High-Speed Data Transmission: Reliably supports demanding bandwidth requirements for modern networks.
• Enhanced Bend Performance: Corning fiber typically offers excellent bend insensitivity, minimizing signal loss.
• Easy Handling and Termination: Tight buffer design simplifies the connectorization process, saving installation time and costs.
• Improved Safety: LSZH jacket contributes to a safer environment in case of fire, crucial for populated areas.
• Long-Term Reliability: Built with high-quality materials for durable and consistent performance.
• Future-Proofing: Invest in a cable that can support your network’s growing bandwidth needs.

Applications:

• Data Centers Interconnects (Server to Switch, Switch to Switch)
• Enterprise Network Backbones
• Horizontal Cabling & LANs
• Storage Area Networks (SANs)
• Telecommunication Closets
• Fiber to the Desk (FTTD) applications
• High-speed connections within buildings requiring LSZH compliance.

4. FAQ Section:

• Q1: What is OM3 fiber and what speeds can it support?A1: OM3 is a laser-optimized multimode fiber (LOMMF) designed for 850nm VCSEL-based transmission. It can support 10 Gigabit Ethernet up to 300 meters, 40 Gigabit Ethernet up to 100 meters, and 100 Gigabit Ethernet up to 100 meters (using MPO connectors and parallel optics).
• Q2: What is the difference between OM3 and OM4 fiber?A2: Both are 50/125µm LOMMF. OM4 offers higher bandwidth (4700 MHz·km vs. 2000 MHz·km for OM3), allowing for longer transmission distances for 40G and 100G Ethernet (e.g., 10G up to 550m, 40G/100G up to 150m on OM4). Choose based on your distance and future bandwidth needs.
• Q3: What does “LSZH” mean, and why is it important?A3: LSZH stands for Low Smoke Zero Halogen. LSZH cables produce minimal smoke and no toxic halogen compounds when exposed to fire, making them safer for indoor environments, especially in confined spaces or areas with sensitive equipment and personnel.
• Q4: What is “simplex” cable?A4: A simplex fiber optic cable has a single strand of fiber and is typically used for applications that require one-way data transmission. For two-way communication, two simplex cables (one for transmit, one for receive) are often used, or a duplex cable (which contains two fibers in a single jacket) can be utilized.
• Q5: What does “tight buffer” mean for this cable?A5: A tight buffer cable has a layer of plastic coating directly applied over the primary fiber coating. This construction provides additional protection, makes the fiber easier to handle, and allows for direct termination of connectors onto the fiber.
• Q6: Can this cable be used outdoors?A6: No, this cable is specifically designed and rated for indoor use due to its LSZH jacket. Outdoor cables require different jacketing materials for UV and moisture protection.
• Q7: What connectors are typically used with this type of OM3 cable?A7: Common connectors include LC, SC, and ST. The choice depends on the equipment and patch panels you are connecting to.
