Lenovo 00YL637

Overview

The Lenovo 00YL637 is a 3 meter active optical cable designed to provide direct 10 Gigabit Ethernet connections between servers, switches, and other devices equipped with SFP+ ports. By using fiber optic strands instead of traditional copper conductors, it maintains signal integrity over the full 9.84-foot length while avoiding electromagnetic interference and crosstalk common in twinax cables. This cable is ideal for short-distance, high-speed data links in dense rack environments.

Each end features a male SFP+ connector, eliminating the need for separate transceiver modules and simplifying installation. Its slim, flexible jacket supports neat cable management and helps maintain airflow in crowded racks, while the lightweight fiber construction reduces strain on switch ports when multiple cables are bundled.

Key features

• Active optical fiber design ensures stable 10 Gigabit Ethernet performance over 3 meters without signal degradation
• Direct-attach SFP+ connectors allow quick plug-and-play setup without additional transceivers
• Fiber construction resists electromagnetic interference, providing cleaner data transmission in electrically noisy environments
• Slim and flexible cable jacket supports efficient routing and preserves airflow in dense server racks
• Lightweight design reduces mechanical stress on ports when multiple cables are installed together
• Ideal for connecting top-of-rack switches to nearby servers, storage arrays, or lab equipment requiring frequent reconfiguration

Key specs

• Cable length: 3 meters (9.84 feet)
• Connector type: SFP+ male on both ends
• Data rate: up to 10 Gigabit Ethernet
• Cable type: active optical fiber
• Compatible with devices supporting SFP+ ports

Connectivity and compatibility

This cable is designed to work seamlessly with any networking equipment that supports SFP+ interfaces, including servers, switches, and storage devices. Its direct-attach design means no additional transceiver modules are required, simplifying deployment and reducing overall cost. The 3 meter length fits well in rack-to-rack connections or short-distance links within data centers or lab environments.

Ideal uses and environments

The Lenovo 00YL637 is well suited for data center professionals and IT administrators who need reliable, high-speed connections over short distances. It works effectively in virtualization clusters, storage replication setups, and high-speed backup operations where maintaining signal quality and minimizing electromagnetic interference are critical. Its flexible and lightweight design also makes it a strong choice for environments where cable management and airflow are priorities.

Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
