Unarmored Multi-Mode Network Patch Cord

The unarmored multi-mode network patch cord is a lightweight, flexible fiber-optic solution optimized for short-haul, high-bandwidth applications in low-risk indoor environments. Unlike armored cords, it lacks a rigid protective layer, relying instead on a durable yet pliable jacket to shield the fiber core—this design reduces weight, improves flexibility, and lowers costs, making it ideal for data centers, enterprise offices, schools, and healthcare facilities, where physical damage risks are minimal.

This patch cord uses 50/125um (OM3/OM4) or 62.5/125um multi-mode fiber, with 50/125um being the modern choice for high-speed performance. 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, and high-definition video streaming. The unarmored design preserves multi-mode’s key advantage: compatibility with low-cost VCSEL transceivers, which reduces overall network expenses compared to single-mode or armored alternatives.

Flexibility is a defining strength of the unarmored design. The jacket (typically LSZH or PVC) is thin and pliable, allowing easy routing through cable trays, wall cavities, or rack-mounted cable managers without kinking—critical for dense data center racks where space is at a premium. Its lightweight construction also simplifies installation; technicians can handle and terminate the cord without specialized tools, reducing downtime during network upgrades. The lack of armor also makes it more compact, fitting into tight spaces like under-desk cable organizers or small server enclosures.

Compliant with TIA/EIA-568-C.3 and IEC 61754-4, this patch cord works seamlessly with all multi-mode indoor hardware. It is available in lengths from 0.5 meters (for desktop-to-router connections) to 50 meters (for long indoor runs) and color-coded (aqua for OM3/OM4, orange for 62.5/125um) for easy cable management. For organizations prioritizing flexibility, cost-effectiveness, and high bandwidth in low-risk settings, the unarmored multi-mode network patch cord delivers the perfect balance of performance and practicality.
