BlueOptics Q28-AOC-7M-LE-BO καλώδιο InfiniBand/οπτικών ινών 7m OM3

The BlueOptics Q28-AOC-7M-LE-BO is a 7m QSFP28 to QSFP28 active optical cable (AOC) engineered for short-range, high-speed data links in rack and adjacent-rack environments. It uses OM3 multimode fibre with a 50 µm core diameter and integrates electrical-to-optical and optical-to-electrical conversion within the QSFP28 connectors to deliver 100GBASE-SR4 compatible performance. The cable combines a small bend radius and reduced weight compared with direct attach twinax solutions, and its LSZH (low smoke zero halogen) jacket reduces smoke and halogen emission in case of fire.

Advantages

The integrated QSFP28 transceiver modules follow MSA and SFF/IEEE guidelines for hot-pluggable operation, providing plug-and-play connectivity for compatible switches, routers and NICs. As an AOC, it offers greater flexibility and lighter cabling than passive twinax solutions while maintaining high signal integrity for 100 Gb/s links. The cable assembly is factory tested for functionality and built using components from established manufacturers to support consistent performance and longevity.

Suitable for

• High-density server-to-switch connections inside racks
• Inter-rack links between adjacent cabinets
• 100GBASE-SR4 Ethernet and InfiniBand short-reach applications
• Data centre top-of-rack and spine deployments

Key specifications

• Cable type: Active Optical Cable (AOC)
• Length: 7 meters
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm
• Supported data rate: 100 Gb/s (compatible with 100GBASE-SR4)
• Jacket material: LSZH (low smoke, zero halogen)
• Bend radius: small bend radius suitable for high-density routing

How to use

Ensure both network devices support QSFP28 modules and are powered down or follow hot-swap procedures recommended by the device vendor. Align the QSFP28 connector latches with the host ports and insert until the connector engages. Verify link and port status on connected equipment; the built-in optical transceivers handle conversion and negotiation automatically. For removal, release the latch mechanism and withdraw the connector straight out to avoid strain on the cable and port.

Recommendations

Route the cable to avoid sharp bends and mechanical stress; maintain manufacturer-recommended minimum bend radius. Use AOC connections for short-distance, high-bandwidth links within and between adjacent racks. Confirm compatibility with your switch or host firmware and monitor link diagnostics after installation. Store and handle the cable by the connector housings to protect the fibre assembly and transceiver components.
