BlueOptics Q28-AOC-7M-MV-BO Cable de fibra óptica InfiniBand 7m OM3

The BlueOptics Q28-AOC-7M-MV-BO InfiniBand fibre optic cable 7m OM3 is an active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for high-speed short‑reach connections within racks or between adjacent racks. Built on OM3 multimode fibre with a 50 µm core diameter, this 7 metre AOC delivers electrical-to-optical conversion in the connector heads to support 100GBASE-SR4 and InfiniBand links while maintaining a reduced weight and improved flexibility compared with direct attach twinax solutions.

Advantages

This active optical cable provides QSFP28 connectivity with integrated I/O and O/E converters for reliable signal conversion and lower insertion losses over short distances. The OM3 multimode fibre supports high bandwidth and efficient transmission for data centre and HPC environments. The cable assembly uses LSZH (low smoke zero halogen) flame‑resistant sheathing for improved safety in confined equipment spaces, and its smaller bend radius and lighter construction simplify routing and installation inside dense racks.

Suitable for

• Short‑reach 100G Ethernet (100GBASE‑SR4) connections between switches and servers
• InfiniBand high‑performance computing interconnects within rack and adjacent rack environments
• High‑density data centre cabling where reduced weight and flexible routing are required
• Upgrades from DAC to optical links to increase reach and reduce signal degradation from cable bundling

Key specifications

• Connector type: QSFP28 to QSFP28 with integrated electrical/optical conversion
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm multimode core
• Cable length: 7 metres
• Application: 100GBASE‑SR4 and InfiniBand short‑reach links
• Sheathing: LSZH (low smoke, zero halogen), flame resistant
• Bend performance: reduced minimum bend radius compared with twinax equivalents

How to use

Install the BlueOptics Q28-AOC-7M-MV-BO by inserting each QSFP28 connector into the appropriate QSFP28 ports on the network equipment until the connector latches. The active modules handle the electrical-to-optical and optical-to-electrical conversion automatically; no separate transceiver modules are required. Route the cable to avoid excessive sharp bends and secure it to prevent strain on connectors. For reliable operation, ensure connected devices support QSFP28 AOC interfaces and are configured for compatible 100G or InfiniBand link settings.

Recommendations

Verify link compatibility (100GBASE‑SR4 or InfiniBand) and QSFP28 port support before installation. Use gentle routing and proper cable management to preserve the OM3 fibre performance; avoid tight bends and crushing. Store and handle the cable in a clean environment and inspect connector ferrules for contamination before mating. For installations in areas requiring halogen‑free materials, confirm LSZH sheathing meets local safety requirements.
