AOC SFP28 25GBASE-SR Active Optical Cable BlueOptics for Lenovo 4X97A94012 10m

The AOC SFP28 25GBASE-SR Active Optical Cable in BlueOptics blue is a factory-terminated multimode fiber assembly designed for direct connection between SFP28 ports. With a 10 m cable length and support for 25GBASE-SR, this active optical cable delivers low-latency, high-bandwidth short-reach links suitable for data center top-of-rack, server-to-switch and switch-to-switch interconnects. The cable is intended as a plug-and-play fiber alternative to copper DACs where optical reach and immunity to electromagnetic interference are required.

Advantages

This BlueOptics AOC combines a compact SFP28 form factor with active optical transceiver technology to provide consistent 25 Gbps throughput over multimode fiber. The 10 m length enables flexible rack-to-rack or aisle connections without intermediate patching. The optical design reduces susceptibility to electrical noise and ground loops compared with copper assemblies, and the lightweight fiber construction lowers cable bulk in dense cable environments.

Suitable for

• Short-reach data center interconnects (top-of-rack to aggregation)
• High-speed uplinks between switches and network appliances
• Direct server-to-switch connections requiring 25 Gbps bandwidth
• Environments where electromagnetic immunity and low latency are important

When it may not be suitable

This active optical cable is intended for short-reach multimode links and is not suitable for long-distance single-mode backbone connections. Environments that require passive copper DACs for power delivery or specific copper-based management features should use a compatible copper solution instead. Also ensure compatibility with the host device SFP28 port firmware and vendor interoperability lists before deployment.

Key specifications

• Interface type: SFP28 to SFP28
• Data rate: 25 Gbps per lane (25GBASE-SR)
• Fiber type: Multimode fiber (OM3/OM4 recommended)
• Maximum nominal length: 10 m
• Connector style: Factory-terminated SFP28 optical connectors
• Application: Short-reach Ethernet interconnects in data centers

How to use

Insert each SFP28 module end into the target SFP28 ports on the connected devices while the devices are powered down or according to the vendor hot-plug guidance. Ensure the cable is routed without tight bends and secured to avoid strain on the connectors. After insertion, verify link status and negotiated speed via the device management interface. If link issues occur, check fiber cleanliness and port compatibility, and consult the equipment vendor documentation for required firmware or transceiver settings.

What to consider before purchase

• Confirm SFP28 port compatibility and vendor interoperability with active optical cables
• Verify that multimode fiber reach (10 m) meets the planned cable route requirements
• Choose appropriate multimode grade (OM3/OM4) to match performance needs
• Check device firmware policies for third-party optical modules if applicable

Usage recommendations

Use the cable for short, high-speed links inside racks and between adjacent racks; keep bend radii above manufacturer minimums, inspect and clean connector endfaces before installation, and monitor link health through switch diagnostics to ensure optimal 25GBASE-SR performance.
