BlueOptics InfiniBand/fibre optic cable 2 m QSFP28 Aqua colour Male/Male

The BlueOptics InfiniBand/fibre optic cable 2 m QSFP28 Aqua colour Male/Male is a 2-metre active optical cable (AOC) with QSFP28 connectors on both ends. Designed for high-speed data centre and networking environments, this cable implements the 100GBASE-SR4 transmission profile over multimode fibre and supports simultaneous send/receive operation through integrated transmitter and receiver modules. The aqua-coloured jacket identifies it as a multimode 100G-class QSFP28 AOC suitable for direct connections between compatible switches, servers and storage systems.

Advantages

The cable offers a pre-assembled QSFP28-to-QSFP28 connection that removes the need for field termination or patching and reduces insertion loss compared with discrete patch-cord setups. Built to MSA (Multi-Source Agreement) QSFP28 AOC specifications, it provides high interoperability with hardware platforms that support 100GBASE-SR4 AOCs. Integrated digital diagnostics (DDM/DOM) enable real-time monitoring of supply voltage, laser bias current, optical output/input power and temperature for easier maintenance and troubleshooting. The design emphasizes long operational life and stable performance by using proven optical and electronic components optimized for multimode 100G transmission.

Suitable for

• Direct 100G connections between QSFP28 ports in data centre switches
• High-bandwidth links between servers and storage arrays
• Short-reach multimode fabric links in top-of-rack and leaf-spine architectures
• Environments requiring digital diagnostic monitoring of optical links

• Cable type: Active Optical Cable (AOC) over multimode fibre
• Colour: Aqua (multimode identification)
• Digital diagnostics: DDM/DOM support for real-time optical and electrical parameters
• Suitable for Ethernet, Fibre Channel over Ethernet and similar 100G protocols

How to use

Ensure both devices support QSFP28 AOC modules and the 100GBASE-SR4 profile before installation. Power down or follow hot-plug guidelines of your equipment as recommended by the device manufacturer. Remove any protective caps, align the QSFP28 connector keying and insert the cable until the latch engages. Confirm link status via the host device LEDs or management interface and, if available, read DDM/DOM parameters to verify optical power and temperature levels. For removal, disengage the latch mechanism and pull the connector straight out to avoid stressing the transceiver module.

Recommendations

Place the cable in routing paths that avoid tight bends and excessive tensile stress; adhere to the manufacturer’s minimum bend radius for multimode AOC assemblies. Verify that target hardware supports DDM/DOM if you require remote monitoring. For optimal performance in multimode environments, use recommended multimode fibre patching and avoid mixing different fibre grades in the same link.
