BlueOptics QSFP28 AOC Cable EB5W-compatible 100GBASE-SR4 multimode fiber 30m

The BlueOptics QSFP28 AOC Cable EB5W-compatible 100GBASE-SR4 multimode fiber 30m is an active optical cable designed for short-reach 100 Gbps Ethernet links in data centers and network aggregation environments. This QSFP28 form-factor cable integrates optics and fiber into a single assembly, enabling native 100G connectivity without separate transceivers. At 30 meters, it supports multimode connections between servers, top-of-rack (ToR) switches and high-density optical switches, delivering low-latency, high-bandwidth links for server-to-switch and switch-to-switch interconnects.

Advantages

The cable provides plug-and-play 100GBASE-SR4 performance with reduced component count compared to separate transceiver and fiber assemblies. Integration of active optical modules into the cable reduces power consumption and rack space while simplifying installation and inventory management. Being compatible with EB5W-type interfaces ensures interoperability with equipment expecting that module behavior and QSFP28 pinout, enabling direct, high-speed links for server uplinks and switch backplanes. The 30 m multimode reach is suitable for typical data center row and pod layouts.

Suitable for

• 100 Gbps short-reach links between servers and ToR switches
• Switch-to-switch interconnects within the same data hall or row
• High-density aggregation in data center racks and optical patching panels
• Environments where native QSFP28 connectivity without separate transceivers is preferred

When it may not be suitable

This active multimode optical cable is intended for short-reach multimode deployments; it is not suitable for long-distance single-mode links or campus/outside-plant fiber runs. If your network requires specific vendor-certified optics, extended reach beyond 30 m, or single-mode fiber support, choose a solution engineered for those requirements.

Key specifications

• Form factor: QSFP28 (integrated AOC)
• Data rate: 100 Gbps (100GBASE-SR4)
• Fiber type: Multimode fiber
• Reach: 30 meters
• Cable type: Active Optical Cable (integrated transceivers)
• Typical applications: Server uplinks, ToR and aggregation switch interconnects

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the source and destination devices until the latch engages. Ensure both ends are fully seated and that connected devices are powered on; the link should be negotiated automatically as a native 100GBASE-SR4 connection. Route the cable to avoid sharp bends and mechanical stress; maintain minimum bend radius recommended for multimode AOC assemblies. No separate transceivers or patch cords are required when using this integrated cable.

What to consider before purchase

• Verify QSFP28 port compatibility and vendor acceptance for EB5W-compatible AOC modules on your devices
• Confirm that 30 m multimode reach matches your rack or row layout requirements
• Ensure your switches and servers support 100GBASE-SR4 lanes and required lane mapping

Usage recommendations

For reliable operation, avoid tight bends and excessive strain on the cable, perform link tests after installation, and keep firmware and driver software on connected devices up to date to ensure correct negotiation and performance of 100G links.
