## Summary description

The BlueOptics X66211A-1-BL is a 1 m InfiniBand/fibre optic cable featuring QSFP28 male connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications, ensuring reliable performance and minimal latency.

## Long description

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.
Usage 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.
