Network Cable BlueOptics QSFP-40G-D-AOC-2M QSFP 40GBASE-SR4 2 Meter Blue

The BlueOptics QSFP-40G-D-AOC-2M is an active optical cable engineered for short-range, high-speed interconnects. Compliant with 40GBASE-SR4, this 2-metre QSFP AOC delivers multi-lane 40 Gbit/s connectivity suitable for modern data centre and server fabric environments. The cable combines QSFP form-factor connectors with integrated optics to eliminate the need for separate transceivers while maintaining signal integrity over a 2 m link.

Advantages

The cable provides plug-and-play installation with QSFP connectors and integrated active components that reduce power consumption compared with discrete optics in some configurations. Its 40GBASE-SR4 compliance ensures compatibility with equipment that supports short-reach multimode links. The fixed 2 m length simplifies cabling planning in racks and top-of-rack deployments, and the blue jacket makes physical identification straightforward during maintenance.

Suitable for

• 40 Gigabit Ethernet switches and server ports supporting QSFP/40GBASE-SR4
• High-density data centre patching and top-of-rack interconnects
• Infiniband FDR10 fabric connections requiring short-reach AOC links
• Equipment racks where a reliable, fixed-length optical link is preferred

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s aggregated over parallel lanes
• Standard: 40GBASE-SR4 for short-reach multimode operation
• Length: 2 metres
• Cable type: Active optical cable (AOC) with integrated transceiver electronics
• Connector color/jacket: Blue

How to use

Insert the QSFP connector ends into compatible QSFP ports on switches, NICs or other network equipment, ensuring the connector keying aligns with the port. No separate transceivers are required; the active optical components are contained within the cable assembly. Verify link status via device LEDs or management interfaces after connection. For safe operation, avoid sharp bends near the connector and ensure secure seating in the port.

Recommendations

Use this 2 m BlueOptics QSFP AOC for short-reach interconnects inside racks or between adjacent racks. Maintain recommended bend radius for fiber assemblies, keep connectors clean and protected when not in use, and confirm compatibility with device QSFP/40GBASE-SR4 support before deployment.
