InfiniBand/fibre optic cable BlueOptics MFA1A00-E004-BO 5 m QSFP28

The BlueOptics MFA1A00-E004-BO is a 5 m active InfiniBand/fibre optic cable with QSFP28 male-to-male connectors designed for 100G short-reach links. It implements a QSFP28-to-QSFP28 connection and supports multimode optical transmission with integrated transmitter and receiver modules on each end. The cable is intended for use in data centers and high-performance computing environments where compact, pre-terminated optical interconnects are required for switches, routers, storage systems and other networking equipment that accept QSFP28 AOC connections.

Advantages

The BlueOptics 5 m QSFP28 active optical cable provides a plug-and-play connection that eliminates the need for separate transceivers and patching, reducing insertion loss and avoiding manual fiber termination. It supports 100G short-range applications over multimode fiber, includes built-in optical transceivers on both ends and offers digital diagnostics monitoring (DDM/DOM) capability for real-time status of supply voltage, laser bias current, optical output and input power and temperature where supported by host hardware. The pre-assembled design minimizes installation time and the cable’s multimode optical link is inherently immune to electromagnetic interference.

Suitable for

• 100G short-reach links between QSFP28 ports in switches and routers
• Interconnects in data center top-of-rack and leaf-spine architectures
• High-performance computing clusters and storage system connections
• Environments requiring low-latency, high-bandwidth optical links

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 5 meters
• Transmission: active optical cable (AOC) for multimode fiber
• Rated data rate: up to 100 Gbit/s for supported protocols
• Supports digital diagnostics monitoring (DDM/DOM) per SFF-8472 where host hardware provides support

How to use

Install the BlueOptics MFA1A00-E004-BO by inserting each QSFP28 connector into the corresponding QSFP28 ports on your networking devices until the latching mechanism engages. Ensure both devices support QSFP28 AOC connections and, if required, verify that the host hardware enables DDM/DOM to read diagnostic values. Avoid excessive bending of the cable and route it to prevent mechanical stress. The cable is pre-terminated and requires no field polishing or splicing.

Usage recommendations

Confirm compatibility with your QSFP28 ports and firmware before deployment. Maintain manufacturer-recommended bend radius for multimode fiber and use existing cable management to secure the AOC to avoid strain on the QSFP28 connectors. For DDM/DOM monitoring, enable the feature in host equipment and consult device documentation for supported diagnostic registers.
