## Long description

The CBO DAC Cable SFP28 for Lenovo SFP-25G-50CM is a 50 cm passive direct attach copper (twinax) cable in blue, designed for short-reach 25GbE connections between SFP28 ports. Compatible with equipment that accepts SFP28 passive twinax assemblies, this cable provides a low-latency, low-power interconnect suitable for data center top-of-rack and server-to-switch links. The integrated SFP28 connector assemblies remove the need for separate optical transceivers, simplifying cabling and reducing component count for densely packed networking environments.
Advantages
The passive twinax construction delivers reduced latency and lower power consumption compared with active optical solutions for short distances, while the fixed 50 cm length keeps signal integrity optimized for rack-level connections. The integrated SFP28 form factor ensures plug-and-play installation in compatible 25GbE ports and minimizes the number of components required in the link. The blue jacket aids visual identification and cable management in multi-cable installations.
Suitable for
 Top-of-rack switch to server connections in data centers
 Inter-switch links within the same rack or adjacent racks
 Short-reach 25GbE uplinks where low latency and low power are required
 Environments that prefer direct attach copper to avoid separate transceivers
Key specifications
 Connector type: SFP28 to SFP28 (passive twinax)
 Data rate: 25 Gigabit Ethernet
 Length: 50 cm
 Cable type: Direct attach copper (DAC), passive
 Jacket color: Blue
 Typical use: Short-reach rack-level interconnects
How to use
Install the cable by inserting each SFP28 connector into the corresponding 25GbE SFP28 port on the devices you wish to connect. Ensure both devices support passive SFP28 direct attach copper cables and that ports are powered down or follow hot-swap guidelines provided by your hardware vendor when inserting or removing modules. Route the cable to avoid sharp bends and excessive mechanical stress; maintain the 50 cm reach for optimal signal performance.
Usage recommendations
Verify compatibility with your switch or server model before deployment, consult equipment vendor documentation for supported passive SFP28 cables, and avoid exceeding bend radius limits. Use the blue cable for organized patching and labeling in rack environments to simplify maintenance and troubleshooting.
