## Summary description

The BlueOptics FN-CABLE-SFP56-DAC-L1-BL is a 1 meter long InfiniBand/fibre optic cable featuring SFP56 connectors on both ends. This high-quality cable ensures reliable data transmission with minimal latency, making it ideal for high-performance computing environments. Its durable black design provides both functionality and aesthetic appeal, while the 1m length offers flexibility in various setups.

## Long description

The BlueOptics FN-CABLE-SFP56-DAC-L1-BL is a 1 meter passive Direct Attach Cable (DAC) with SFP56 connectors on both ends, designed for short-range high-speed InfiniBand and 50GBase-CR connectivity. The cable uses twinax copper construction to transmit electrical signals with low latency and low power consumption, and it is finished in a black jacket for a professional rack appearance. With a compact 1 m length and SFP56 terminations, it is suitable for connections inside racks and between adjacent racks where a short, reliable 50 Gbps-capable link is required.
Advantages
This passive SFP56 DAC provides a cost-effective, low-latency solution for short-distance high-speed links. Its SFP56 connectors on both ends ensure compatibility with equipment supporting SFP56 modules and 50GBase-CR electrical interfaces. The 1 m length reduces excess cable slack in dense rack environments, and the twinax copper design offers low power usage and simple, maintenance-friendly construction. The black outer jacket provides a durable exterior while keeping a discreet appearance in professional installations.
Suitable for
Short-range rack-to-rack or intra-rack connections in data centers
High-performance computing clusters and InfiniBand links
Switch-to-switch, switch-to-server, or switch-to-storage direct connections
Environments requiring low latency and low power passive cabling
Key specifications
Cable length: 1 m
Connectors: SFP56 on both ends
Transmission type: passive twinax copper DAC suitable for 50G electrical links
Typical use: short-range InfiniBand / 50GBase-CR connections
Colour: Black
Weight: 0.08 kg
How to use
Ensure both endpoints support passive SFP56 Direct Attach Cables and the 50GBase-CR electrical standard or the relevant InfiniBand interface. Power down or follow hot-plug guidance for your hardware as recommended by the device manufacturer, then insert the SFP56 connectors firmly into the SFP56 ports until they latch. Route the 1 m cable to avoid sharp bends and mechanical strain; secure it inside the rack to prevent movement. Verify link status via the connected devices and confirm negotiated speed and link integrity in device management interfaces.
Usage recommendations
Use this 1 m passive SFP56 DAC for short, fixed-length connections where low latency and minimal power consumption are priorities. Avoid exceeding recommended bend radius and ensure the connected hardware supports passive twinax DACs. For longer distances or different link types, select an appropriate active cable or fiber solution.
