InfiniBand/fibre optic cable BlueOptics MFA1A00-E01A-BO 2 m QSFP28

The BlueOptics MFA1A00-E01A-BO 2 m QSFP28 InfiniBand/fibre optic cable is a 2-meter active optical cable (AOC) with QSFP28 connectors designed for 100G short-reach links. It integrates transmitter and receiver electronics in each connector and uses multimode fiber to support high-speed optical transmission compliant with MSA QSFP28 interfaces. The male-to-male QSFP28 configuration enables direct device-to-device connectivity in switches, routers, storage systems and other data center hardware that supports QSFP28 AOCs.

Advantages

This AOC offers 100G-capable optical transmission over a pre-assembled 2 m cable, eliminating the need for separate transceivers and patch cords. Built to MSA QSFP28 mechanical and electrical specifications, it supports simultaneous send/receive operation on multiple lanes and includes digital diagnostics monitoring (DDM/DOM) for remote status and signal parameter readout. The active design reduces insertion loss concerns associated with connectorized patching and provides immunity to electromagnetic interference typical for fiber links.

Suitable for

• High-density data center interconnects between QSFP28-capable switches and routers
• Server-to-switch or switch-to-switch connections requiring 100G short-reach links
• Storage systems and SAN fabrics using 100G optical links
• Environments where compact pre-assembled fiber connections and reduced maintenance are required

Key specifications

• Form factor: QSFP28 to QSFP28 active optical cable
• Cable length: 2 meters
• Data rate: up to 100 Gbit/s (100GBASE-SR4 applications)
• Fiber type: multimode fiber with integrated transceivers in connectors
• Digital diagnostics: DDM/DOM support for real-time monitoring (when supported by host hardware)
• Connector orientation: male QSFP28 on both ends

How to use

Insert each QSFP28 connector into compatible QSFP28 ports until the latch engages. Ensure both connected devices support AOC modules and the 100GBASE-SR4 or equivalent protocol used on the link. Verify that the host hardware supports digital diagnostics if you need access to voltage, temperature, laser bias and optical power readings. No additional transceivers or patch cables are required; the pre-assembled cable provides a direct optical connection.

Usage recommendations

Use the cable in short-reach optical links within the specified 2 m length and avoid kinking or tight bends that can stress the cable assembly. Confirm compatibility with the target devices’ QSFP28 ports and firmware support for active AOCs. When installing in racks, route the cable to minimize strain on the QSFP28 connectors and ensure adequate airflow around equipment to maintain operating temperatures.
