Lenovo 5M QSFP + to QSFP+ Active Optical Cable

The Lenovo 00YL655 is a 5 meter active optical cable that carries QSFP+ connectors on both ends, giving data center teams a straightforward way to run 40 Gbps links between switches, servers, and storage platforms.

Because the cable relies on a fiber optic signal path with built-in electronics, it delivers clean transmission that resists electromagnetic interference and keeps latency predictable. These characteristics matter when supporting virtualization clusters, high performance computing nodes, or any workload that needs consistent throughput.

With a reach of 16.4 feet, the assembly fits comfortably inside a single rack or across adjacent cabinets. Administrators can link top-of-rack switches to blade enclosures, aggregation switches, or spine layers without managing excess slack. Installation is plug and play: seat each QSFP+ connector in a compatible Lenovo port and the link comes up immediately.

The cable is fully qualified by Lenovo, so it matches firmware expectations and avoids the compatibility warnings that can appear with non-validated hardware. Network engineers working in enterprise data centers, campus cores, or lab environments will find it a reliable option whenever standardized 40 Gbps connectivity is required and a fixed length simplifies planning.

Whether you are upgrading existing infrastructure or building out a new 40 Gbps fabric, the Lenovo 00YL655 provides a single, purpose-built assembly that helps keep the network design clean, predictable, and easy to maintain.
