BlueOptics MFA1A00-C007-BO InfiniBand fibre optic cable 7 m QSFP28

The BlueOptics MFA1A00-C007-BO InfiniBand fibre optic cable 7 m QSFP28 is an active optical cable (AOC) engineered for short-reach, high-bandwidth connections. With QSFP28 to QSFP28 male connectors and a 7 metre multi-mode fibre link, this cable supports up to 100 Gbit/s data rates and is designed for use in data centres, high-performance computing and network equipment that accept QSFP28 AOC solutions.

Advantages

This 7 m InfiniBand AOC provides a fully integrated transmitter and receiver on each connector end, reducing the need for separate transceivers and simplifying installation. The QSFP28 interface follows common MSA standards for compatibility with hardware platforms that support Mellanox-compatible MFA1A00-C007 AOC modules. The multi-mode fibre construction is optimised for short-range, high-speed links and supports protocols such as Ethernet and Fibre Channel over Ethernet at line rates up to 100 Gbit/s over the specified cable length.

Suitable for

• Interconnecting QSFP28 ports on switches and routers within racks and across adjacent racks
• Short-reach links in data centre top-of-rack and spine-leaf architectures
• High-performance computing clusters and storage arrays requiring 100G links
• Environments using Ethernet or Fibre Channel over Ethernet at 100G

Key specifications

• Cable type: Active Optical Cable (AOC) with multi-mode fibre
• Connector style: QSFP28 male to QSFP28 male
• Length: 7 metres
• Maximum supported data rate: up to 100 Gbit/s
• Supported transmission: short-reach multimode links suitable for 100GBASE-SR4 type applications

How to use

Connect the QSFP28 male connector on one cable end to a QSFP28 port on the first device and insert the opposite QSFP28 male connector into the corresponding port on the second device. Ensure ports are powered and configured for the intended protocol (for example Ethernet or Fibre Channel over Ethernet) and that the connected hardware officially supports QSFP28 AOC modules of this type. No external transceivers are required because the optical transmitter and receiver are integrated into the cable ends.

Recommendations

Store the cable in a dry, dust-free environment and avoid tight bends or kinks; respect the manufacturer’s minimum bend radius. Use the 7 m length for short-reach links within and between adjacent racks. Verify compatibility with your switch, router or storage hardware before deployment and perform link tests after installation to confirm 100G operation.
