Cabo de fibra ótica InfiniBand BlueOptics 30 m QSFP28 aqua

The BlueOptics InfiniBand fibre optic cable 30 m QSFP28 Aqua is a 30-metre active optical cable (AOC) with QSFP28 connectors, designed for 100G multi-mode links in data centre and high-performance computing environments. The cable supports SR4-type optical transmission and provides a factory-assembled QSFP28-to-QSFP28 connection with integrated transmitter and receiver electronics on each end. The aqua-coloured jacket aids visual identification and organised cabling runs.

Advantages

This BlueOptics AOC implements the QSFP28 electrical and optical interface for short-range 100G connections, enabling high throughput with low latency and immunity to electromagnetic interference. Built to MSA-aligned mechanical and optical specifications, the cable integrates high-quality lasers and control ICs for reliable long-term operation. Digital diagnostics support is included for online monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where the host hardware exposes DDM/DOM data.

Suitable for

• 100G interconnects between switches and routers in data centres
• High-performance computing clusters and server-to-server links
• Storage systems and SAN top-of-rack connections
• Short-reach optical links where QSFP28 to QSFP28 is required

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
• Length: 30 metres
• Data rate: up to 100 Gbit/s (SR4 multimode transmission)
• Fiber type: multimode optical fibre designed for short-range 100G links
• Colour: aqua (for easy identification)
• Digital diagnostics: supports DDM/DOM parameters (voltage, bias current, Tx/Rx power, temperature) when supported by host
• Compliance: MSA-aligned mechanical and electrical interface for QSFP28

How to use

Install the BlueOptics QSFP28 AOC by inserting the QSFP28 plugs into compatible QSFP28 ports on network switches, routers or servers. Ensure ports and host devices support QSFP28 modules and, if digital diagnostics are required, that the host exposes DDM/DOM functionality. Route the aqua cable to avoid sharp bends and excessive pulling; follow standard fibre handling practices to preserve optical performance. No additional transceivers or patch cables are required when using the pre-terminated AOC.

Recommendations

Avoid tight bends (adhere to the specified minimum bend radius), protect connectors from dust and mechanical damage, and confirm firmware/OS compatibility with non-original AOCs if the host enforces vendor checks. For diagnostic access, enable DDM/DOM support on the host platform. Regular visual inspection of connectors and cable routing helps maintain reliable 100G links.
