Indoor Multi-Mode Network Patch Cord

　　The indoor multi-mode network patch cord is a versatile fiber-optic solution optimized for short-haul, high-bandwidth applications in controlled indoor settings like data centers, enterprise offices, schools, and healthcare facilities. Unlike outdoor cords, it prioritizes flexibility, compactness, and fire safety over weather resistance—making it ideal for connecting devices within a single building or enclosed space.

　　This patch cord uses 50/125um or 62.5/125um multi-mode fiber, with 50/125um (OM3/OM4) being the preferred choice for modern high-speed networks. The wider 50μm core transmits multiple light beams, supporting data rates up to 10 Gbps (550 meters with OM4) and 40 Gbps (150 meters with OM4)—perfect for bandwidth-intensive tasks like server-to-switch connections, SAN links, video conferencing, and high-definition media streaming. The multi-mode design also works with low-cost VCSEL transceivers, reducing network costs compared to single-mode alternatives.

　　The indoor-focused construction includes a flame-retardant jacket (typically LSZH or low-smoke PVC) that meets strict fire safety standards (e.g., UL 94 V-0 or IEC 60332-1). LSZH jackets are especially popular in enclosed spaces like data centers or hospitals, as they emit minimal smoke and no toxic fumes in case of fire. The cord is lightweight and flexible, making it easy to route through cable trays, wall cavities, or rack-mounted cable managers without kinking or damaging the fiber. Common connector options include LC (small-form-factor for high-density racks) and SC (robust for easy handling), both with low insertion loss (<0.3dB) and compatibility with indoor hardware.

　　Compliant with TIA/EIA-568-C.3 and IEC 61754-4 standards, this patch cord works seamlessly with all multi-mode indoor equipment. It is available in lengths from 0.5 meters (for desktop-to-router connections) to 50 meters (for long indoor runs) and is color-coded (aqua for OM3/OM4, orange for 62.5/125um) for easy cable management. For organizations needing high-bandwidth, cost-effective connectivity in controlled indoor environments, the indoor multi-mode network patch cord offers the perfect blend of performance, safety, and flexibility—supporting modern data demands without the unnecessary bulk of outdoor-rated cables.
