## Summary description

The BlueOptics JNP-QSFP-DAC-50CM-BL is a 0.5m InfiniBand cable featuring QSFP male connectors on both ends. It is designed for high-speed data transfer in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics JNP-QSFP-DAC-50CM-BL InfiniBand Cable is a 0.5 m direct attach twinax copper cable with QSFP male connectors on both ends. Designed for short-range, high-speed interconnects in racks and adjacent rack systems, it supports 40GBase-CR4 data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand protocols where a passive QSFP-to-QSFP connection is required. The cable follows MSA-compliant dimensions and 30 AWG wiring for stable electrical transmission at short distances.
Advantages
This 0.5 m passive DAC delivers low latency and very low power consumption, making it appropriate for dense data center environments. Built from high-quality components and designed to meet MSA specifications, the cable provides reliable mechanical fit and consistent signal performance. The passive design eliminates active electronics in the cable, reducing failure points and production complexity while offering a cost-effective connectivity option for short links.
Suitable for
 Short-range server-to-switch or switch-to-switch connections within racks
 High-performance computing and InfiniBand clusters requiring 40 Gbit/s links
 Storage arrays and SAN links using Fibre Channel or FCoE at 40G
 Environments where low latency and low power per link are priorities
Key specifications
 Cable type: passive twinax copper (DAC)
 Connector type: QSFP male to QSFP male
 Length: 0.5 metre
 Supported link rate: up to 40 Gbit/s (40GBase-CR4)
 Wire gauge: 30 AWG
 Standards: MSA-compliant QSFP form factor
 Typical power consumption: ~0.1 W per link (passive operation)
How to use
Install the cable by fully inserting each QSFP connector into the corresponding QSFP port on the networking equipment until the latch engages. Use the cable for direct electrical connections between QSFP-enabled ports on switches, routers, storage controllers or server adapters that support passive DACs and the 40GBase-CR4 electrical specification. Verify that connected devices are configured for the appropriate protocol and link speed; no external power or transceiver configuration is required for the cable itself.
Usage recommendations
Avoid tight bends and mechanical stress on the cable; maintain the manufacturer’s minimum bend radius to ensure signal integrity. Use this passive DAC for short, rack-level connections—if you need longer runs or optical isolation, select an active DAC or fiber-based QSFP solution. Confirm device compatibility with passive QSFP DACs in vendor documentation before deployment.
