BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Aqua

The BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Aqua is a 7‑meter active optical cable (AOC) with QSFP28 male-to-male connectors designed for high‑speed links in data center and networking environments. It supports 100G optical transmission over multimode fiber using a QSFP28‑to‑QSFP28 interface and includes transceivers on both ends to convert electrical to optical signals. The cable is intended for direct connections between compatible switches, routers, storage systems and other network devices that accept QSFP28 AOCs.

Advantages

This BlueOptics AOC implements the QSFP28 form factor and is built to MSA‑compatible specifications for 100GBASE‑SR4 multimode applications, offering a plug‑and‑play QSFP28 to QSFP28 connection without separate transceiver modules. The active optical design reduces bulk and attenuation compared with long copper assemblies and eliminates susceptibility to electromagnetic interference. The integrated transceivers support simultaneous transmit and receive optical channels and include digital diagnostics (DDM/DOM) capabilities where supported by the host hardware.

Suitable for

• High‑speed 100G interconnects between switches and routers within data centers
• Connections between storage systems and network aggregation devices
• Short‑reach multimode fibre links inside server rooms and equipment racks

Key specifications

• Length: 7 meters
• Connector type: QSFP28 male to QSFP28 male
• Data rate: up to 100 Gbps (100GBASE‑SR4 multimode operation)
• Transmission medium: multimode fibre (active optical cable)
• Form factor: QSFP28 AOC with integrated transmitters and receivers
• Digital diagnostics support (DDM/DOM) when enabled by host device

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on the source and destination devices until the latch engages. Verify that both devices support QSFP28 AOCs and, if required, enable or check firmware settings for third‑party AOC compatibility. The cable is pre‑terminated and requires no additional field splicing or connector assembly. For diagnostic information, use the host system’s management interface to read DDM/DOM parameters if the platform exposes these values.

Recommendations

Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius for multimode active cables. Ensure ports and cable ends are free of debris before insertion and confirm that connected hardware supports QSFP28 AOCs and the 100GBASE‑SR4 multimode profile to access full performance and diagnostics.
