BlueOptics NC8VD-BO InfiniBand optický kábel 30 m QSFP28 aqua

The BlueOptics NC8VD-BO InfiniBand fibre optic cable 30 m QSFP28 Aqua is a 30-metre active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for 100G multimode links in data centre and high-performance computing environments. It implements the 100GBASE-SR4 transmission profile over multimode fibre and includes integrated transmitters and receivers on both ends to handle optical signalling. The cable is compatible with systems that support QSFP28-based 100GBASE-SR4 AOCs and is intended for short-reach, high-bandwidth interconnects between switches, routers, storage systems and compute nodes.

Advantages

The BlueOptics NC8VD-BO provides a pre-terminated, plug-and-play QSFP28 connection that eliminates the need for field splicing or patch-cord assemblies, reducing installation time and potential signal loss. As an active optical cable, it delivers high data rates up to 100 Gbit/s over a 30 m multimode link while remaining immune to electromagnetic interference. The integrated digital diagnostics monitoring (DDM/DOM) capability enables real-time readout of operating parameters such as supply voltage, laser bias, output/input optical power and temperature for easier troubleshooting and remote monitoring.

Suitable for

• 100G interconnects between switches and aggregation devices in data centres
• High-performance computing (HPC) clusters and storage fabric connections
• Short-reach uplinks and server-to-switch links within racks or across adjacent racks
• Environments requiring QSFP28 QSFP28 active optical cable solutions with DDM support

• Use case: short-reach multimode fibre interconnects in data centre infrastructure

How to use

Install the BlueOptics NC8VD-BO by plugging each QSFP28 connector into the corresponding QSFP28 port on the devices to be connected, ensuring device firmware and hardware support for QSFP28 100GBASE-SR4 AOCs and DDM if diagnostic data is required. Handle the cable by the connector housings and route the optical cable to avoid sharp bends; follow standard multimode fibre bend-radius guidelines. No additional transceivers or patching are required because the cable is pre-assembled and terminated. If DDM is available on the host hardware, enable or query the diagnostic interface through the device management tools to monitor optical parameters.

Recommendations

Verify device compatibility with QSFP28 100GBASE-SR4 AOCs before installation and confirm that the host supports DDM/DOM if you intend to use diagnostic functions. Maintain bend radius and keep connectors free of dust; use protective caps when ports are not in use. For critical links, test the cable in the target environment prior to deployment and consider keeping a sample for compatibility verification in multi-vendor setups.
