## Summary description

The BlueOptics SFP28-DAC-0.5M-BL is a high-quality 0.5m DAC cable featuring SFP28 connectors. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics SFP28-DAC-0.5M-BL is a 0.5 m direct attach cable (DAC) with SFP28 connectors designed for short-distance, high-speed interconnects in data centers and network racks. This passive twinax copper cable supports 25GBase-CR class electrical links and is intended for connecting compatible switches, routers, storage systems and other hardware that accept SFP28 DAC modules. The product combines a compact 0.5 m length with SFP28-to-SFP28 connectivity and a lightweight construction for rack-to-rack or in-rack cabling.
Advantages
The cable offers a low-latency, low-power solution for 25 Gbps links with simple passive operation, reducing power consumption compared to active optical modules. Its short length and twinax copper design deliver consistent electrical signal transmission for supported protocols while minimizing latency and insertion loss. The cable is built using MSA-compliant SFP28 connectors and materials suitable for professional installations, providing a reliable lifetime for repeated plug cycles and stable connectivity in dense rack environments.
Suitable for
Short-distance links inside racks or between adjacent racks
25 Gbps Ethernet connections (25GBase-CR)
FCoE, Fibre Channel and InfiniBand applications up to 25 Gbps
High-density switch-to-switch or switch-to-server cabling
Key specifications
Cable length: 0.5 m
Connector type: SFP28 to SFP28
Supported data rate: up to 25 Gbps (per supported standard)
Cable type: passive twinax copper (30 AWG)
Typical power consumption: passive (near 0.1 W for comparable passive DACs)
Colour: black and silver exterior elements
Weight: approximately 0.08 kg
How to use
Ensure both port endpoints officially support passive SFP28 DACs and the 25GBase-CR electrical specification. Power down or follow hot-plug guidance from your hardware vendor if required, then insert each SFP28 connector into the corresponding SFP28 port until it latches. Confirm link negotiation and speed in the device management interface and check for stable status LEDs or administration indicators. For removal, release the connector latch and gently withdraw the plug following the vendor's handling instructions.
Usage recommendations
Use this 0.5 m SFP28 DAC for short, fixed interconnects where fiber is unnecessary and where the host hardware explicitly supports passive twinax SFP28 cables. Avoid sharp bends, excessive tensile stress, and exposure to liquids or extreme temperatures. Verify compatibility with your switch or server firmware and request a test sample in mixed environments if interoperability is critical.
