## Summary description

The BlueOptics SFP28-DAC-3M-GM-BL is a 1m long InfiniBand fibre optic cable with male SFP28 connectors on both ends. It is designed for high-speed data transfer in data centers and networking applications, ensuring reliable connectivity and performance.

## Long description

The BlueOptics SFP28-DAC-3M-GM-BL InfiniBand fibre optic cable 1 m Black is a short-range direct attach cable with SFP28 male connectors on both ends, designed for high-speed connections in racks and between adjacent racks. It supports 25G data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications when used with compatible SFP28 ports. The cable is manufactured to meet MSA electrical and mechanical specifications and is intended as a compact, low-latency link for data centre hardware that accepts passive SFP28 twinax connections.
Advantages
This SFP28 direct attach cable provides a cost-effective and energy-efficient connection method for short-distance links. As a passive twinax solution it requires no active components, resulting in low power consumption and low latency. The cable follows industry MSA standards for interoperability and is assembled using components from established suppliers to provide reliable signal integrity and an extended operational lifetime.
Suitable for (tasks / use cases)
 High-speed links between switches and routers within a rack or across adjacent racks
 Server-to-switch and storage-to-switch short-distance connections
 25G Ethernet, FCoE, Fibre Channel and InfiniBand interconnects
 Environments where low latency and low power consumption are required
Key specifications
 Connector type: SFP28 male to SFP28 male
 Length: 1 metre
 Nominal data rate: up to 25 Gbit/s
 Cable type: passive twinax copper (DAC) suitable for short-range electrical transmission
 Wire gauge: 30 AWG
 MSA-compliant electrical and mechanical interface
 Low power consumption and low latency typical of passive DAC solutions
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 cage on your compatible devices until the connector latches. Confirm that the host hardware and firmware support passive SFP28 DAC cables and the required 25GBase-CR protocol. For best performance, route the cable to avoid sharp bends and mechanical stress and ensure the connected devices are powered and configured for the intended link speed and protocol.
Usage recommendations
Verify device compatibility before deployment and, if possible, test a sample in your specific hardware and software environment. Use passive SFP28 DACs for short distances inside racks or between adjacent racks; for longer runs consider active DACs or optical transceivers with appropriate fibre.
