BlueOptics 4MHC9-BO InfiniBand Fibre Optic Cable 50m QSFP28 Aqua

The BlueOptics 4MHC9-BO InfiniBand Fibre Optic Cable 50m QSFP28 Aqua is a 50-metre active optical cable (AOC) with QSFP28 connectors designed for 100G data links over multimode fiber. Engineered to comply with MSA QSFP28 form-factor and 100GBASE-SR4 transmission profiles, this pre-assembled cable provides a direct QSFP28-to-QSFP28 connection for high-speed data center and networking equipment that support compatible QSFP28 AOCs.

Advantages

This BlueOptics 50 m AOC integrates transmitter and receiver modules at each end to reliably convert electrical signals to optical signals and back, enabling low-latency, high-bandwidth links without the need for field termination. The product is tested for compatibility with major hardware platforms that accept QSFP28 100G AOCs. Built with components from established suppliers for lasers and ICs, the cable is intended to offer stable performance, digital diagnostic monitoring (DDM/DOM) support for remote link diagnostics, and a long expected service life.

Suitable for

• 100G Ethernet interconnects between QSFP28 ports in switches and routers
• High-performance computing and InfiniBand-compatible environments requiring 100G links
• Storage systems and SAN installations with QSFP28 interfaces
• Short-range data center trunking and spine-leaf connections up to 50 metres

Key specifications

• Length: 50 metres
• Connector type: QSFP28 to QSFP28
• Transmission type: Active Optical Cable (AOC) for multimode fiber
• Supported data rate: up to 100 Gbps (100GBASE-SR4 profile)
• Color / jacket: aqua (multimode fiber standard color)
• Digital diagnostics: DDM/DOM support for real-time monitoring of optical parameters

How to use

Install the BlueOptics 4MHC9-BO by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices. Ensure ports are powered and configured to accept QSFP28 AOC modules, then verify link status via device management interfaces. Use the DDM/DOM telemetry (if supported by host hardware) to monitor voltage, temperature, laser bias and optical power levels for troubleshooting and preventive maintenance.

Recommendations

For best results, route the cable to avoid tight bends and mechanical strain; follow your data center’s bend radius and cable management practices. Confirm host-device compatibility with QSFP28 AOCs and enable DDM/DOM support on compatible hardware to access diagnostic data. Use the cable within the specified 50 m distance for the 100GBASE-SR4 profile to maintain expected link performance.
