## Summary description

The BlueOptics QSFP-100G-CU1M-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. This cable ensures reliable performance and low latency, making it ideal for connecting switches, servers, and storage devices.

## Long description

The BlueOptics QSFP-100G-CU1M-BL InfiniBand fibre optic cable is a 1 m twinax direct attach cable with QSFP28 male connectors on both ends, designed for high-speed short-reach interconnects in data-centre and rack environments. It supports 100G data rates and is suitable for use with switches, servers and storage systems that accept QSFP28 direct attach copper assemblies. The cable offers low latency, low power consumption and a compact form factor for dense rack installations.
Advantages
This QSFP28 direct attach cable provides a cost-effective and energy-efficient interconnect for short-distance links. As a passive twinax assembly it requires no additional power for signal conversion and delivers low latency and stable electrical performance. The 1 m length is optimized for connections within racks or between adjacent racks, reducing clutter while preserving signal integrity. Compliance with common MSA electrical and mechanical specifications ensures broad interoperability with hardware platforms that support QSFP28 DACs.
Suitable for
 100G connections between QSFP28 ports in the same rack
 Interconnects between adjacent racks and short data centre runs
 Linking switches, routers, storage arrays and servers with QSFP28
 Environments requiring low-latency, high-throughput links
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Length: 1 metre
 Media: Passive twinax copper (direct attach)
 Supported data rate: up to 100 Gbps
 Wire gauge: 30 AWG twinax
 Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand up to 100G
 Form factor: QSFP28 compliant MSA mechanical dimensions
How to use
Install the cable by firmly inserting each QSFP28 connector into the corresponding QSFP28 port on your devices until the connector latch engages. Use the 1 m length to connect ports within the same rack or between adjacent racks, avoiding sharp bends and excessive pulling. Verify that the host hardware and firmware support passive QSFP28 DACs and configure the interfaces according to your device vendor instructions. Monitor link status through your switch or server management interface to confirm successful negotiation at 100G.
Usage recommendations
For reliable operation, keep bend radius within the manufacturer’s specified limits and avoid running the cable near high-interference power sources. Ensure both endpoints support passive QSFP28 DACs and the intended protocols (Ethernet, FCoE, Fibre Channel, InfiniBand). For critical links consider testing a sample unit with your specific hardware and firmware versions prior to deployment.
