Cabo de fibra ótica InfiniBand BlueOptics AFBR-7QER03Z-BO 3 m QSFP macho/macho

The BlueOptics AFBR-7QER03Z-BO is a 3 m InfiniBand/fibre optic active optical cable (AOC) with QSFP connectors on both ends, designed for 40G data transmission. It implements 40GBASE-SR4 signaling over multi-mode fiber and provides a pre-assembled QSFP-to-QSFP link with integrated transmitter and receiver modules on each end. The cable follows MSA QSFP specifications to ensure interoperability with hardware that supports the corresponding 40G AOC form factor and protocol.

Advantages

This 3 m BlueOptics AOC delivers high-speed 40G connectivity with low latency and immunity to electromagnetic interference due to its optical transmission. The integrated transceivers and tested component selection provide consistent interoperability with major networking platforms and allow plug-and-play installation without field termination. The cable supports digital diagnostics for real-time monitoring of voltage, laser bias current, transmit power, receive power and temperature, enabling easier troubleshooting and maintenance.

Suitable for

• 40G interconnects between QSFP-enabled switches and routers in data centers
• High-performance computing clusters using InfiniBand or 40G Ethernet
• Connections to storage systems and SAN fabrics requiring low-latency optical links
• Short-reach multi-mode fiber links inside racks and between adjacent racks

Key specifications

• Length: 3 meters
• Connector type: QSFP to QSFP (male/male)
• Supported protocol: 40GBASE-SR4 (40 Gbit/s)
• Medium: multi-mode fiber, active optical cable (AOC)
• Integrated transceiver modules with DDM/DOM monitoring (MSA SFF-8472 compliant)
• Designed for short-reach data center applications and rack-to-rack connections

How to use

Install the BlueOptics AFBR-7QER03Z-BO by inserting each QSFP connector into QSFP ports on the required devices while the devices are powered according to vendor guidelines. The active optical cable is pre-terminated and requires no splicing; ensure ports support 40GBASE-SR4 or compatible QSFP AOC modules. If the connected hardware supports digital diagnostics, access the DDM/DOM registers via the device management interface to monitor operating parameters. Follow your equipment manufacturer’s instructions for hot-plugging and firmware compatibility to avoid link-negotiation issues.

Recommendations

Use in rack and short-reach data center environments for links up to 3 m. Verify that your switches, routers or storage systems officially support QSFP AOC modules and 40GBASE-SR4 signaling. Keep connector endfaces and port areas free of dust and follow vendor guidance when handling QSFP modules. For remote monitoring, confirm DDM/DOM support in the host hardware before relying on diagnostic telemetry.
