BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Aqua colour Male/Male

The BlueOptics InfiniBand/fibre optic cable 7 m QSFP28 Aqua colour Male/Male is a 7-meter active optical cable (AOC) with QSFP28 connectors designed for 100G data transmission over multimode fiber. It implements the 100GBASE-SR4 transmission profile and provides a pre-assembled QSFP28-to-QSFP28 link for direct connection between compatible switches, routers, storage systems and other network hardware. The cable supports simultaneous send and receive channels through integrated optical transceivers on each connector and includes digital diagnostics monitoring (DDM/DOM) support when the host hardware exposes this interface.

Advantages

This 7 m BlueOptics AOC follows MSA-compliant QSFP28 electrical and mechanical specifications to ensure interoperability with systems that support QSFP28 100GBASE-SR4 modules. As an active optical cable it offers immunity to electromagnetic interference and low latency transmission over multimode fiber. Each end contains an integrated transmitter and receiver, allowing plug-and-play installation without the need to terminate or clean individual fiber connectors. Digital diagnostics provide real-time information such as supply voltage, laser bias current, optical transmit/receive power and temperature for remote monitoring and troubleshooting.

Suitable for

• Direct 100G connections between QSFP28 ports in data center switches and routers
• High-performance storage area network links and SAN interconnects
• Low-latency InfiniBand or Ethernet aggregation and spine-leaf topologies
• Short-reach multimode fiber backbone connections within racks or between adjacent racks

Key specifications

• Length: 7 meters
• Connector type: QSFP28 to QSFP28, male/male
• Transmission standard: 100GBASE-SR4 (multimode fiber)
• Data rate: up to 100 Gbit/s
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Color: Aqua (typical multimode color coding)
• Digital diagnostics monitoring (DDM/DOM) compliant with SFF-8472 (if supported by host)
• MSA-compliant QSFP28 electrical and mechanical interface

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the connector latch engages. Ensure both host ports support QSFP28 100GBASE-SR4 or compatible QSFP28 AOC operation. If your equipment supports DDM/DOM, enable diagnostic monitoring via the device management interface to read real-time optical and electrical parameters. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by the cable manufacturer and secure the cable to reduce stress on ports and connectors.

Recommendations

Verify hardware compatibility with QSFP28 AOC modules and confirm that the host firmware/drivers accept third-party AOCs if applicable. Use the DDM/DOM readings for preventive maintenance and confirm multimode fiber environments (OM3/OM4) for optimal 100GBASE-SR4 performance. Avoid exposing the cable to excessive pulling forces, crushing, or tight bends to preserve optical performance and lifetime.
