## Summary description

BlueOptics SFP-H25G-CU1M is a 1-meter SFP28 direct attach copper cable (DAC) supporting 25GBASE-CR. Designed for short-range high-speed connections between compatible SFP28 ports, it provides a fixed, low-latency link for switches, servers and network appliances. The passive copper assembly in blue is suitable for rack-to-rack or chassis interconnects where a cost-effective 25 Gbps link is required.

## Long description

BlueOptics SFP-H25G-CU1M 25GBASE-CR SFP28 direct attach cable is a 1 meter passive copper assembly designed to provide a fixed 25 Gbps electrical connection between compatible SFP28 ports. The blue cable offers a low-latency, short-reach link for rack-to-rack and chassis interconnects in data centers and network equipment racks. It is intended for environments where a cost-effective, simple 25GBASE-CR connection is required without the need for optical transceivers or separate patch cables.
Advantages
The 1 m passive DAC provides deterministic latency and low power consumption compared with active optical solutions. As a direct attach cable, it eliminates the need for separate transceivers and fiber patching, reducing component count and simplifying installation. The blue jacket makes cable identification easier in dense cabling environments, and the SFP28 form factor ensures compatibility with devices that support 25GBASE-CR electrical interfaces.
Suitable for
 Short-reach 25 Gbps direct connections between SFP28 ports in switches and routers
 Server to top-of-rack switch links within the same rack or adjacent racks
 Chassis-to-chassis interconnects in modular network systems
 Cost-sensitive deployments requiring fixed copper connectivity at 25G
Key specifications
 Form factor: SFP28 direct attach cable (DAC)
 Data rate: 25 Gbps (25GBASE-CR)
 Length: 1 meter
 Cable type: passive copper assembly
 Color: blue jacket
 Connector interface: SFP28 electrical
 Typical usage: short-reach, rack/chassis interconnect
How to use
Insert each SFP28 connector into the corresponding SFP28 port on network devices until the connector latch engages. Ensure both ends are seated firmly and that the connected devices support 25GBASE-CR over SFP28 passive copper assemblies. No additional configuration is required at the physical layer beyond verifying link status on the devices. Handle the cable by the connector bodies to avoid stressing the cable assembly and ensure proper cable management to prevent excessive bends or strain.
Usage recommendations
Use the cable for short-distance connections (within a rack or between adjacent racks). Maintain bend radius and avoid sharp kinks; keep the cable clear of high-heat sources and heavy mechanical stress. Verify device compatibility with passive SFP28 DACs and confirm firmware or port settings if link negotiation issues occur.
