BlueOptics JL276A-BO InfiniBand fibre optic cable 7 m QSFP28 Aqua

The BlueOptics JL276A-BO InfiniBand fibre optic cable 7 m QSFP28 Aqua is a 7-metre active optical cable (AOC) with QSFP28 connectors on both ends. Designed for high-speed data transmission in data centre and networking environments, this cable follows MSA-compliant QSFP28 AOC specifications and supports 100GBASE-SR4 class multimode optical links. The aqua jacket identifies it for high-speed multimode network use and the pre-assembled AOC design provides a ready-to-use fibre connection without separate patch cords.

Advantages

The cable provides simultaneous transmit and receive optical channels through QSFP28-to-QSFP28 connectivity and integrates transceivers at each end for reliable optical signal conversion. Being manufactured to MSA guidelines, it offers interoperability with hardware that supports QSFP28 AOCs and 100GBASE-SR4 multimode applications. Digital diagnostic monitoring (DDM/DOM) capabilities are supported where host hardware exposes these functions, enabling remote measurement of parameters such as supply voltage, temperature and optical power levels. The pre-terminated AOC form factor reduces installation time and eliminates the need for polishing or cleaning patchcord ferrules in short interconnect runs.

Suitable for

• Server-to-switch and switch-to-switch interconnects within data centres over short multimode spans
• High-performance computing clusters using InfiniBand or 100G Ethernet links
• Storage systems and SAN uplinks requiring 100G multimode connections

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Connectors: QSFP28 to QSFP28, duplex multimode optical channels
• Length: 7 metres
• Performance class: Designed for 100G multimode short-range applications (100GBASE-SR4 equivalent)
• Jacket colour: Aqua (identifies multimode/high-speed use)
• Monitoring: Supports Digital Diagnostic Monitoring / Digital Optical Monitoring when host hardware provides support

How to use

Install the BlueOptics JL276A-BO by inserting each QSFP28 connector into compatible QSFP28 ports on switches, routers, servers or storage modules while the devices are powered down or hot-plugged according to the host vendor guidance. Ensure ports are QSFP28 AOC compatible and configured for the intended protocol (100G Ethernet, InfiniBand or Fibre Channel over Ethernet). If DDM/DOM data is required, verify that the host device exposes diagnostic registers for the cable. Avoid tight bends and mechanical strain on the cable; follow the manufacturer’s minimum bend radius during routing.

Usage recommendations

Check compatibility with your hardware vendor’s list of supported QSFP28 AOCs before deployment and, if possible, test the cable in a non-production environment to confirm link negotiation and diagnostic visibility. Maintain appropriate airflow and secure routing to prevent stress or damage to the cable over its operating life.
