## Summary description

The BlueOptics Q+DA0005-BL is a 5 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics Q+DA0005-BL InfiniBand/fibre optic cable 5 m QSFP Male/Male is a 5 metre high-speed direct attach cable with QSFP connectors on both ends. Designed for short-reach links in rack and adjacent-rack environments, it supports 40 Gbps applications including Ethernet, FCoE, Fibre Channel and InfiniBand where QSFP-to-QSFP connectivity is required. The cable is a passive twinax solution intended for reliable, low-latency signal transmission in data centers and networking equipment that accept QSFP passive direct attach cables.
Advantages
The cable provides a cost-effective option for short-distance, high-bandwidth interconnects, combining low power consumption and simple passive design to reduce failure points. Manufactured to MSA-compliant form factors and populated with industry-standard components, it offers compatibility with major hardware platforms that support QSFP passive direct attach twinax cables. The 5 m length enables flexible rack and adjacent-rack cabling without requiring active transceivers.
Suitable for
 40 Gbps QSFP-to-QSFP connections between switches
 Interconnects between routers and storage systems within racks
 Short-distance links in data center top-of-rack and adjacent-rack deployments
 Applications using Ethernet, FCoE, Fibre Channel or InfiniBand protocols up to 40 Gbps
Key specifications
 Length: 5 metres
 Connector type: QSFP male to QSFP male
 Data rate support: up to 40 Gbps
 Cable type: passive twinax direct attach cable
 Form factor: QSFP (MSA-compliant)
How to use
Insert each QSFP connector into the corresponding QSFP port on supported network devices until the connector latches. Ensure both devices support passive QSFP direct attach twinax cables and the chosen protocol (Ethernet, FCoE, Fibre Channel or InfiniBand) at 40 Gbps. Route the cable within the rack or between adjacent racks avoiding sharp bends and excessive tension. No separate power or transceivers are required for passive operation; device port settings and link negotiation should be verified via the host hardware.
Usage recommendations
Use the cable for short-reach links (recommended up to 5 m) in controlled data center environments. Verify device compatibility with QSFP passive DACs before deployment and avoid repeated excessive flexing. For longer distances or environments requiring optical isolation, consider active optical cables or transceiver plus fiber solutions.
