SpeedyCables OM4 LC-LC Fiber Patch Cable 3M/10ft 6-Pack – 40G/100G MMF Duplex, LSZH Magenta

High-performance, scalable fiber connectivity for modern networks

SpeedyCables delivers an OM4 LC-LC patch cable set in a vivid magenta LSZH jacket. Built around 50/125 μm multimode duplex fiber, these cables are designed to support fast, data-heavy links while prioritizing indoor safety and easy identification in dense rack environments. Real-world results depend on complete system design and proper transceiver pairing, but the cobble of materials and precision engineering aims to maximize reliability across active data paths.

Whether you're upgrading a data center spine, expanding a telecom room, or provisioning a cloud-ready SAN, these cables are crafted to fit the needs of high-bandwidth networks that rely on quick terminations and solid signal integrity.

Key capabilities

• High-speed potential: 50/125 μm multimode duplex fiber with LC-LC connectors, compatible with 10G, 40G, and 100G Ethernet specifications; designed to support very high data rates in optimized configurations.
• Extended reach for robust networks: 4700 MHz·km at 850 nm with practical lengths of up to 400 m for 10G, 350 m for 40G, and 125 m for 100G, enabling stable transfers across larger racks and rooms.

Safety, durability, and ease of use

• LSZH jacket: low-smoke, reduced halogen emissions, making it a safer indoor option for server rooms and data centers.
• Magenta color and clear labeling help with quick audits and organized cable management in busy environments.

Versatility and installation details

These cables are designed for compatibility with common transceivers such as SFP+, QSFP+, and BIDI SR, making them a flexible choice for a wide range of network topologies. They also feature a bend radius of 7.5 mm, low insertion loss (≤0.3 dB), and high return loss (≥30 dB), supporting dependable signal integrity in dense deployments.

Coming in a 6-pack of 3 m (approximately 10 ft) lengths, this set offers ready-to-deploy links for multi-link rack configurations, simplifying inventory and upgrade planning while maintaining a consistent performance profile across cables.

In real-world use, customers may notice smoother panel terminations, clearer labeling for patch panels, and improved cable organization in tight spaces—benefits that contribute to faster maintenance and fewer misroutes during routine upgrades or expansions.
