## Summary description

The BlueOptics V43KP-BL is a 0.5 m InfiniBand/fibre optic cable featuring QSFP Male/Male connectors. It ensures high-speed data transfer and reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics V43KP-BL InfiniBand/fibre optic cable 0.5 m QSFP Male/Male is a short-range direct attach twinax copper cable designed for high-speed 40G connections between QSFP ports. With a 0.5 meter length and QSFP-to-QSFP connectors, this passive 40GBase-CR4 cable supports Ethernet, FCoE, Fibre Channel and InfiniBand protocols where short-distance, low-latency links are required. The cable follows MSA-compliant design and is compatible with hardware platforms that support the original Dell/Mellanox V43KP specification.
Advantages
The cable provides reliable 40 Gbps data transfer over short distances with low power consumption and reduced latency compared with active optical transceivers. Constructed using high-quality twinax copper and manufactured components from established suppliers, it is engineered for long-term availability and consistent performance. As a passive direct attach cable, it does not require additional power or complex configuration and is optimized for rack-to-rack and within-rack interconnects.
Suitable for
High-density rack interconnects between switches and servers
Short-distance links in data centres and network closets
Connections for storage systems and SAN fabrics
40G Ethernet, FCoE, Fibre Channel and InfiniBand links up to 0.5 m
Key specifications
Connector type: QSFP Male to QSFP Male
Cable type: passive twinax copper (40GBase-CR4)
Length: 0.5 m
Wire gauge: 30 AWG
Data rate: up to 40 Gbps
Compliance: MSA-compliant design
Power consumption: passive, negligible additional power (approx. 0.1 W typical for system)
How to use
Connect each QSFP connector to the corresponding QSFP port on compatible switches, routers, servers or storage devices while the devices are powered down or according to the vendor’s hot-swap guidelines. Verify that the host hardware and firmware support passive 40GBase-CR4 twinax direct attach cables. After physical insertion, confirm link status and negotiated rate on the devices’ management interfaces. Avoid tight bends and protect the cable from mechanical stress to preserve signal integrity.
Usage recommendations
Use this 0.5 m QSFP Male/Male DAC for short, high-speed interconnects inside racks or between adjacent racks. Ensure compatibility with the specific hardware platform and firmware version before deployment, and route the cable to prevent kinks or compression. For installations requiring longer distances or optical isolation, consider appropriate active optical cables or transceivers.
