BlueOptics X66211A-1-BL InfiniBand/fibre optic cable 1 m QSFP28 Black

The BlueOptics X66211A-1-BL InfiniBand/fibre optic cable is a 1 m high-speed connection with QSFP28 male connectors on both ends, designed for short-range links in data centers and rack environments. It supports up to 100G data transmission and is intended for low-latency, high-throughput interconnects between switches, routers, storage systems and server NICs that accept QSFP28 to QSFP28 connections. The cable is a passive direct attach twinax solution built to MSA-compatible mechanical and electrical specifications for reliable interoperability.

Advantages

The cable provides a compact, low-power connection with minimal latency for short-distance links. Compliance with MSA-compatible QSFP28 form-factor and use of high-quality components ensure stable signal integrity and consistent performance across supported platforms. Passive twinax construction reduces complexity and power consumption compared with active optic alternatives, while supporting common protocols such as Ethernet, FCoE, Fibre Channel and InfiniBand up to 100G on a 1 m span.

Suitable for

• Short-distance rack-to-rack and within-rack interconnects in data centers
• 100G QSFP28 links between switches, routers and storage arrays
• High-throughput, low-latency InfiniBand or Ethernet connections

Key specifications

• Length: 1 meter
• Connector type: QSFP28 male to QSFP28 male
• Data rate support: up to 100 Gbps
• Cable type: passive twinax direct attach
• Wire gauge: 30 AWG twinax
• Form-factor compatibility: QSFP28 / MSA-compliant

How to use

Identify two QSFP28-capable ports on compatible network devices and ensure both devices support passive direct attach twinax cables. Align and insert the QSFP28 connectors into the device ports until the latch engages. Verify link status on both devices and configure interfaces according to your network protocols (Ethernet, FCoE, Fibre Channel, InfiniBand) and addressing. For removal, depress the connector latch and pull straight out to avoid bending the cable assembly.

Recommendations

Use this BlueOptics 1 m QSFP28 twinax cable for short, fixed connections inside racks or between adjacent racks. Avoid excessive bending near the connector ends and keep the cable strain-relieved to preserve signal integrity. Confirm device compatibility with passive DACs and validate configuration after installation.
