BlueOptics AFBR-7QER07Z-BO InfiniBand fibre optic cable 7 m QSFP

The BlueOptics AFBR-7QER07Z-BO InfiniBand fibre optic cable 7 m QSFP is an active optical cable (AOC) designed for short-range, high-bandwidth connections in data centres and enterprise networks. With QSFP-to-QSFP connectors and a 7 metre multi-mode fibre link, this cable supports 40 Gbps class applications including 40GBASE-SR4, providing low-latency optical transmission for switches, routers and storage systems that accept QSFP AOC modules.

Advantages

This AOC integrates transmitters and receivers in the QSFP housings to ensure stable optical signal conversion and minimal signal loss over the 7 m distance. Conformity with QSFP MSA physical interface conventions promotes interoperability with major hardware platforms. The use of multi-mode fibre and active transceivers reduces electromagnetic interference and removes the need for separate transceiver modules and patch cords, simplifying rack-to-rack connections within data centre racks and rows.

Suitable for

• 40 Gbps switch-to-switch interconnects in data centres
• Server to switch or storage system connections requiring QSFP ports
• High-throughput fabrics and InfiniBand environments over short distances
• Environments where low latency and reduced electromagnetic interference are required

Key specifications

• Connector type: QSFP-to-QSFP (QSFP form factor)
• Length: 7 metres
• Data rate: supports 40 Gbps class applications (40GBASE-SR4 compatible)
• Fibre type: multi-mode fibre with integrated active transceivers
• Form factor: active optical cable with integrated Tx/Rx per connector
• Typical use case: short-reach, high-bandwidth optical links within racks and between adjacent racks

How to use

Insert each QSFP connector into compatible QSFP ports on your network devices, ensuring the connector latch engages and the port supports AOC modules and the targeted 40G protocol. Route the 7 m cable to avoid tight bends and mechanical stress; maintain the cable bend radius recommended for multi-mode fibre to preserve signal quality. Power is provided by the integrated transceivers through the QSFP ports, so no separate power or module installation is required beyond proper seating in device ports.

Recommendations

Check device compatibility with QSFP AOC modules and ensure firmware or hardware listings include support for 40G AOC links. Use the cable for short-reach connections up to 7 m in controlled environments; avoid exposure to excessive temperature extremes, moisture or physical abrasion. For critical deployments, verify link performance with diagnostic tools after installation.
