Lenovo 00YL637 3M SFP+ to SFP+ Active Optic Cable

The Lenovo 00YL637 is a 3 meter active optical cable built for direct plug-in 10 Gigabit Ethernet links between servers, switches, and other devices that use SFP+ ports. By transmitting data over fiber strands instead of copper conductors, it preserves signal quality across the entire 9.84 foot run and avoids the crosstalk or electromagnetic noise that can limit traditional twinax cables.

Each end of the cable has a male SFP+ interface, so there is no need for separate transceiver modules; installation is as simple as inserting the latch into the port until it clicks. Once seated, the connection can negotiate full line-rate throughput, supporting workloads such as virtualization clusters, storage replication, or high-speed backup operations.

Administrators who manage dense racks will value the cable’s slim jacket, which bends easily for neat routing and leaves airflow paths unobstructed. The absence of metal conductors also reduces weight, helping to lower strain on switch ports when several cables are bundled together.

Use the Lenovo 00YL637 to link a top-of-rack switch to a row of rack-mounted servers, to connect storage arrays that sit only a few meters away, or to establish a lab bench where equipment must be reconfigured frequently. Wherever a point-to-point 10 G link with dependable performance over a short distance is required, this active optical cable provides a straightforward solution.

Highlights:

• 3 meter active optical fiber cable with SFP+ connectors at both ends
• Supports up to 10 Gigabit Ethernet throughput
• Direct-attach design removes the need for separate transceivers
• Fiber construction resists electromagnetic interference and reduces weight
• Fits server, switch, and storage links over short rack-to-rack distances
