BlueOptics Q28-AOC-25M-SW-BO InfiniBand glasvezelkabel 25m OM3

The BlueOptics Q28-AOC-25M-SW-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and a flame-retardant LSZH sheath. The built-in optical/electrical conversion in each QSFP28 module enables hot-pluggable installation and reliable connections between devices inside a rack or between adjacent racks.

Advantages

This QSFP28 to QSFP28 25m AOC provides lighter weight and greater flexibility compared to direct attach twinax (DAC) cables, as well as a smaller bend radius and reduced cable diameter. The integrated I/O and O/E converters support 100GBASE-SR4 applications and remove the need for separate transceiver modules. The cable is manufactured to MSA-compatible SFF and IEEE specifications, uses high-quality components from established manufacturers, and is factory tested for functionality and compliance with CE and RoHS standards.

Suitable for

• High-speed server-to-switch or switch-to-switch connections in data centers
• Inter-rack connections between adjacent racks
• Short-reach 100GBASE-SR4 InfiniBand and Ethernet links
• Environments requiring flame-retardant (LSZH) cabling

• Hot-pluggable: yes
• Compliance: manufactured to MSA/SFF and IEEE-related specifications; factory-tested

How to use

Install the QSFP28 connectors into compatible QSFP28 ports on network devices following the equipment vendor's instructions. Ensure both ends are clean and free of dust before insertion. The cable is hot-pluggable, so it can be connected or disconnected while systems are powered, subject to the host device recommendations. Route the cable with gentle bends to respect the specified bend radius and avoid tight corners or pinching; use rack management accessories where necessary to maintain orderly cabling.

Recommendations

For reliable 100G performance, use the cable for short-reach links within and between adjacent racks and avoid exceeding the specified bend radius. Verify QSFP28 port compatibility and firmware support on connected devices. Keep connector endfaces clean, and store the cable coiled loosely to prevent microbends. Follow site safety and grounding practices and choose LSZH cabling where low smoke and halogen-free properties are required.
