## Long description

The BlueOptics DAC Cable SFP-25G-CU3M-BL is a 3 m passive direct attach copper (DAC) cable with SFP28 connectors on both ends, designed for 25G Ethernet links. It provides a short-reach, low-latency electrical connection for rack-to-rack or intra-rack links in data centres, server rooms and network closets. The cable is black and intended for systems that accept SFP28 to SFP28 direct attach twinax connections following standard MSA physical interfaces.
Advantages
The DAC construction offers low power consumption, minimal latency and stable signal transmission for short-distance 25G links. As a passive twinax copper solution, the BlueOptics SFP-25G-CU3M-BL is simple to install, requires no additional transceivers or power, and delivers predictable electrical performance for compatible network hardware. Its durable jacket and fixed 3 m length support reliable operation in dense rack environments and reduce the need for frequent replacement.
Suitable for
 Connecting switches within the same rack or between adjacent racks
 Linking servers to top-of-rack or leaf switches
 Short-distance interconnects for storage systems and network appliances
 High-density 25G network deployments in data centres and colocation facilities
Key specifications
 Cable type: Passive direct attach copper (DAC), twinax
 Interface: SFP28 to SFP28
 Data rate: Supports 25G Ethernet
 Length: 3 m
 Colour: Black
 Typical use: Short-reach electrical connections (rack-to-rack, intra-rack)
How to use
Power down is typically not required for hot-pluggable SFP28 DAC cables, but follow your hardware vendor’s guidelines for safe insertion and removal. Align each SFP28 connector with the corresponding port on the switch, server or storage device and insert until the latch engages. Verify link training and port status in the device management interface to confirm the 25G connection is active. Use cable routing practices to avoid sharp bends and excessive strain on connectors.
Usage recommendations
Use the BlueOptics SFP-25G-CU3M-BL in environments where short, reliable 25G copper links are required and where the connected devices explicitly support passive SFP28 DAC cables. Avoid using these passive DACs beyond the recommended short-reach distance and consult device compatibility lists if vendor-specific firmware restrictions apply.
