Multi-Mode Network Patch Cord

　　The multi-mode network patch cord with 50/125um core/cladding diameter and SC-SC connectors is optimized for short-distance, high-bandwidth applications, making it a staple in data centers, enterprise server rooms, and local area networks (LANs). The “50/125um” specification denotes a 50μm glass core (wider than single-mode’s 9μm) surrounded by a 125μm cladding—this wider core carries multiple light beams (modes), enabling high data rates over shorter distances (typically up to 550 meters for 10 Gbps, using OM4 fiber).

　　The SC-SC connector is a defining feature of this patch cord. SC connectors use a square, push-pull design with a locking tab, offering easy, tool-free installation and low insertion loss (<0.3dB). Their robust construction—often with ceramic ferrules—ensures reliable connections in high-traffic environments like data centers, where cables are frequently plugged and unplugged during server maintenance or reconfiguration. Unlike smaller LC connectors, SC connectors are easier to handle with gloved hands, a practical benefit for data center technicians.

　　This patch cord is ideal for short-haul, high-density applications: connecting servers to top-of-rack (ToR) switches, linking storage area networks (SANs) to servers, or enabling 10 Gbps/40 Gbps connectivity within a data center pod. It supports multi-mode fiber grades like OM3 (up to 300 meters at 10 Gbps) and OM4 (up to 550 meters at 10 Gbps), giving organizations flexibility to match their distance needs. The multi-mode design is also more cost-effective than single-mode for short distances, as it works with lower-cost VCSEL (Vertical-Cavity Surface-Emitting Laser) transceivers, reducing overall network expenses.

　　Constructed with a durable jacket (PVC or LSZH) to resist abrasion and physical damage, and color-coded (typically aqua for OM3/OM4) for easy identification, this patch cord simplifies cable management in dense data center environments. It complies with standards like TIA/EIA-568-C.3 and IEC 61754-4, ensuring compatibility with all SC-enabled multi-mode hardware. Available in lengths from 0.5 meters (for server-to-switch connections) to 100 meters (for longer data center runs), the multi-mode 50/125um SC-SC patch cord balances performance, cost, and ease of use for short-distance high-bandwidth networks.
