## Long description

The BlueOptics DAC Cable SFP-25G-CU5M-BL is a 5 m Direct Attach Copper (DAC) cable with SFP28 connectors on both ends and a black jacket. Designed for short-range, high-speed connections, it supports 25G data transmission and complies with common SFP28 interface requirements. The cable is intended for rack-to-rack or device-to-device connections in data centers and networking closets where a reliable, low-latency copper link is required.
Advantages
This DAC cable provides a low-latency, power-efficient connection for 25G links using passive twinax construction. The fixed-length 5 m cable simplifies rack planning and installation while maintaining signal integrity for short-distance high-bandwidth links. Its SFP28-to-SFP28 terminations ensure direct compatibility with equipment that accepts SFP28 DAC modules, and the black outer jacket offers a discreet appearance in server racks.
Suitable for
Short-range connections between switches, routers and servers in racks
High-density top-of-rack and inter-rack cabling in data centres
Storage systems and network appliances that accept SFP28 DAC modules
Key specifications
Cable type: Direct Attach Copper (DAC), passive twinax
Data rate: up to 25 Gbit/s per link
Connectors: SFP28 on both ends
Length: 5 m
Colour: Black
Application: short-distance electrical 25G links in rack environments
How to use
Insert each SFP28 connector into the appropriate port on the source and destination devices while both devices are powered according to the equipment manufacturer’s installation guidance. Ensure that ports support passive DAC SFP28 modules and that firmware or port settings allow 25G operation. Route the cable to avoid excessive bending and mechanical stress; follow standard rack cable-management practices to maintain airflow and serviceability.
Usage recommendations
Verify hardware compatibility before deployment and, where possible, test the cable in your specific switch or server model to confirm link establishment at 25G. Avoid sharp bends and kinks, and keep the cable away from heat sources to maintain long-term performance.
