InfiniBand/fibre optic cable BlueOptics ACC763-10000S-BL 3 m QSFP28 Male/Male

The BlueOptics ACC763-10000S-BL is a 3 m InfiniBand/fibre optic direct attach cable with QSFP28 connectors on both ends in a male/male configuration. Designed for short-reach, high-speed interconnects in data centers and server racks, this cable supports 100G data rates and is suitable for linking switches, routers, storage systems and other hardware platforms that accept QSFP28 direct attach connections. The cable combines a passive twinax copper structure with QSFP28 terminations for reliable electrical transmission over a 3 metre distance.

Advantages

The cable provides a compact, low-latency connection for high-bandwidth links while consuming minimal power. Its QSFP28 male-to-male configuration enables direct linking of compatible ports without additional transceivers. Manufactured to industry MSA guidelines and using high-quality components, the cable offers stable performance for Ethernet, Fibre Channel and InfiniBand applications at up to 100 Gbit/s over a 3 m span.

Suitable for

• Short-range rack-to-rack and intra-rack 100G interconnects
• High-performance switching and routing interlinks
• Storage area network connections and server uplinks
• Environments requiring low-latency, high-bandwidth links (InfiniBand, Ethernet, FCoE)

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Supported data rate: up to 100 Gbit/s
• Cable type: passive twinax copper direct attach
• Wire gauge: 26 AWG
• Standards: MSA-compliant physical form factor
• Typical applications: Ethernet, Fibre Channel, InfiniBand, FCoE

How to use

Ensure both devices support passive QSFP28 direct attach cables and that the ports are designed for 100GBase-CR4 or equivalent protocols. With equipment powered down or following hot-plug guidelines from your hardware vendor, align each QSFP28 plug with the port and insert until the latch engages. Confirm link negotiation and speed through the device management interface and monitor for correct operation. For removal, release the latch and withdraw the connector straight out to avoid stress on the port.

Recommendations

Use this 3 m QSFP28 direct attach cable for short-distance connections inside racks or between adjacent racks. Avoid sharp bends, excessive pull force, and exposure to high electromagnetic interference. Verify hardware compatibility with your vendor's list for passive DACs and test new links during maintenance windows to validate performance and interoperability.
