InfiniBand/fibre optic cable BlueOptics 73CV5-BL 2 m QSFP28 Male/Male

The BlueOptics 73CV5-BL is a 2 m InfiniBand/fibre optic cable with QSFP28 connectors on both ends, designed for high-speed data transmission and reliable rack-to-rack connectivity. It supports 100G applications over short distances and is compatible with hardware platforms that accept QSFP28 direct attach cables. The cable is a passive direct attach twinax solution with 30 AWG conductors and complies with MSA guidelines for QSFP28 interconnects, making it suitable for switches, routers and storage systems in data center environments.

Advantages

The cable offers low latency and low power consumption typical of passive direct attach twinax solutions while providing 100G data throughput at 2 m length. Constructed from high-quality components and tested for compatibility with major hardware platforms, it provides stable electrical signal transfer for Ethernet, FCoE, Fibre Channel and InfiniBand protocols. Its design emphasizes straightforward installation, minimal maintenance and predictable long-term performance.

Suitable for

• Short-distance 100G links between adjacent racks or within a rack
• Connections between switches, routers and storage systems supporting QSFP28 DACs
• High-density data center interconnects requiring low latency
• Environments using Ethernet, FCoE, Fibre Channel or InfiniBand at 100G

Key specifications

• Cable length: 2 meters
• Connector type: QSFP28 to QSFP28, male/male
• Transmission rate: up to 100 Gbps (protocol dependent)
• Cable type: passive direct attach twinax copper
• Conductor gauge: 30 AWG
• Compliance: MSA-compliant QSFP28 interconnect

How to use

Insert the QSFP28 connectors into the QSFP28 ports of the devices to be connected, ensuring alignment and a firm seating without excessive force. Use the cable for short-distance links up to 2 m where both devices support passive DAC QSFP28 connections. Verify device compatibility and firmware or driver requirements before deployment. Avoid sharp bends and mechanical strain on the cable and connectors during installation.

Recommendations

For reliable operation, use the cable in rack and adjacent-rack connections where passive QSFP28 DACs are supported by the hardware. Maintain proper cable management to prevent kinks and limit exposure to high temperatures. If interoperability with a particular vendor is critical, test the cable in your environment prior to large-scale deployment.
