Suitable for top-of-rack, spine/leaf and data center server uplinks where a passive 25G DAC is required.

## Long description

Direct attach copper cable BlueOptics SFP-25G-D-CAB-3M 25GBASE-CR 3 m is a passive SFP28 twinax assembly designed for short-reach 25 Gbit/s connections. The 3-meter fixed cable integrates SFP28 connectors on both ends and provides a low-latency, energy-efficient copper link between switches, servers and network appliances. It is intended for 25GBASE-CR applications in data center top-of-rack, spine/leaf or server uplink deployments where a cost-effective, reliable interconnect is required.
Advantages
The direct attach copper cable delivers predictable signal performance for short distances with lower power consumption compared with active optical modules. Its integrated SFP28 connectors simplify installation and reduce the number of separate transceivers and patch cords. The passive construction minimizes heat dissipation and eliminates the need for external power, while the fixed-length design reduces inventory complexity and ensures consistent link characteristics.
Suitable for
Top-of-rack switch to server uplinks in data centers
Spine-and-leaf network fabrics requiring 25 Gbit/s links
Short-reach interconnects between switches and network appliances
Key specifications
Interface: SFP28 to SFP28 (fixed twinax cable)
Nominal data rate: 25 Gbit/s
Standard: 25GBASE-CR
Length: 3 m (fixed)
Cable type: Passive copper twinax
Typical use: Short-reach direct attach interconnect
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the networking equipment until the latch engages. Verify link status on connected devices and confirm the interface negotiates at 25 Gbit/s. No additional configuration is required for physical connectivity beyond standard port settings; if necessary, check device compatibility and port settings in the switch or server management interface.
Usage recommendations
Use this passive DAC for rack-to-rack or within-rack short links up to 3 meters. Avoid tight bends near the connector ends and maintain minimum bend radius to preserve signal integrity. For mixed-vendor environments, verify SFP28 port compatibility and any vendor-specific port settings before deployment.
