Cabo de fibra ótica InfiniBand BlueOptics MFA1A00-E007-BO 7 m QSFP28 macho/macho

The BlueOptics MFA1A00-E007-BO InfiniBand fibre optic cable 7 m QSFP28 Male/Male is a 7-metre active optical cable (AOC) with QSFP28 connectors on both ends designed for high-speed links in data centre and high‑performance computing environments. The cable implements 100GBASE-SR4-type multimode transmission with integrated transmitters and receivers in the QSFP28 assemblies, enabling 100 Gb/s connections over a 7 m multimode fibre link. It is compatible with systems that accept QSFP28 AOC modules for short-reach 100 Gb/s interconnects and is intended for direct device-to-device connections such as switch-to-switch, switch-to-server or switch-to-storage interconnects.

Advantages

This active optical cable provides low-latency, high-bandwidth connectivity with the small form factor of QSFP28 connectors. By integrating optical transceivers into the cable ends, it eliminates the need for separate transceiver modules and patch cords, reducing connector count and simplifying rack cabling. The 7 m length offers a balance between rack-to-rack flexibility and predictable optical loss for short-reach 100 Gb/s links. Multimode fibre operation supports typical data centre link budgets for short-range high-speed protocols such as Ethernet and Fibre Channel over Ethernet.

Suitable for

• 100 Gb/s switch-to-switch connections within racks and between adjacent racks
• Server or storage to aggregation switch uplinks at short reach
• High-performance computing cluster node interconnects
• Environments requiring QSFP28 AOC short-range 100G links

Key specifications

• Cable type: Active Optical Cable (AOC) with multimode fibre
• Connector type: QSFP28 male to QSFP28 male
• Nominal data rate: up to 100 Gb/s (SR4-type multimode operation)
• Length: 7 metres
• Form factor: QSFP28 small form-factor pluggable assembly integrated in cable ends
• Typical applications: Ethernet, Fibre Channel over Ethernet, short-reach high-speed interconnects

How to use

Insert each QSFP28 connector into a compatible QSFP28 port on the devices to be linked, ensuring proper orientation and a secure mechanical latch. Devices should be powered and configured to use the QSFP28 AOC as a 100 Gb/s interface; most modern switches and servers will auto-negotiate or allow manual interface configuration for 100G operation. Avoid tight bends and excessive pulling forces on the cable; route it through cable management to prevent kinking and to maintain optical performance. When removing the cable, release the mechanical latch before pulling the connector from the port.

Recommendations

Use this 7 m QSFP28 AOC for short-reach 100G connections within racks or to adjacent racks where a direct active optical cable eliminates the need for separate transceivers and patch panels. Verify device compatibility with QSFP28 AOC modules and ensure port firmware or driver support for SR4/multimode 100G links before deployment.
