BlueOptics Q+DA0001-BL InfiniBand/fibre optic cable 1 m QSFP Male/Male

The BlueOptics Q+DA0001-BL InfiniBand/fibre optic cable is a 1 m QSFP-to-QSFP direct attach solution designed for short-range, high-speed links in data centres and rack environments. It supports 40G throughput over a passive twinax connection and is compatible with equipment that accepts QSFP interfaces for Ethernet, FCoE, Fibre Channel and InfiniBand applications. The cable is intended for 1 m interconnects between adjacent devices or within server and network racks where reliable, low-latency connectivity is required.

Advantages

This 1 m QSFP male-to-male cable offers a compact, low-power connection with passive twinax construction that requires no active electronics for transmission. The design delivers low latency and stable signal integrity for short-distance 40G links. Manufactured to MSA-compliant mechanical and electrical specifications using quality components, the cable is suitable for continuous operation and long service life in professional networking environments.

Suitable for

• Inter-rack and intra-rack connections in data centres
• 40G links between switches, routers and servers
• Storage area network (Fibre Channel) and FCoE deployments
• InfiniBand links for high-performance computing clusters

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 1 metre
• Transmission type: passive twinax copper for short-reach 40G links
• Wire gauge: 30 AWG
• Standards: MSA-compliant QSFP electrical interface
• Supported protocols: 40G Ethernet, FCoE, Fibre Channel, InfiniBand
• Typical power consumption: passive cable, negligible additional power

How to use

Install the BlueOptics Q+DA0001-BL by firmly inserting each QSFP connector into the corresponding QSFP port on supported switches, routers or storage devices. Ensure that the host hardware supports passive direct attach twinax cables and that port configurations match the intended 40G protocol. Avoid excessive bending near the connector heads and secure the cable within the rack to prevent strain. For best results, perform link verification and test traffic after installation to confirm correct operation.

Recommendations

Use this 1 m QSFP twinax cable for short-distance, cost-effective 40G interconnects where passive DACs are supported; avoid using it across longer runs where active optics or fibre would be required.
