## Summary description

Passive SFP28 direct-attach copper (DAC) cable by CBO, model SFP28-DAC-2M, 2 meters long. Designed for 25GbE SFP28 ports to provide reliable short-range connections between switches, routers, servers and NICs. Low-latency, energy-efficient passive design requires no external power or transceivers, simplifying rack cabling and reducing cost for data center and enterprise interconnects.

## Long description

Passive SFP28 DAC copper cable CBO SFP28-DAC-2M is a 2 metre direct-attach copper solution designed for 25GbE SFP28 ports. It provides a fixed, low-latency electrical interconnect between compatible switches, routers, servers and network interface cards without the need for separate transceivers. The passive design consumes no additional power for signal conversion and is intended for short-reach links inside racks or between adjacent racks in data centre and enterprise environments.
Advantages
The cable delivers low latency and consistent signal integrity suitable for high-bandwidth 25GbE links while simplifying rack cabling by eliminating separate optical transceivers. Its passive construction reduces power consumption and operating cost, and the pre-terminated twinax form factor ensures quick plug-and-play installation. The fixed 2 m length provides predictable channel loss and performance for short-range applications.
Suitable for
Short-range 25GbE connections between top-of-rack switches and servers
Interconnects between adjacent racks in data centres
Direct connections to NICs, routers and storage servers with SFP28 ports
Environment where low-latency, energy-efficient links are required
Key specifications
Electrical interface: SFP28 compatible direct-attach copper
Data rate: 25 Gigabits per second per lane
Length: 2 metres
Cable type: Passive twinax copper
Connector style: SFP28 form factor, pre-terminated
Typical use: Short-reach rack and adjacent-rack connections
How to use
Insert each SFP28 connector into compatible SFP28 ports on the two devices until the latch engages. Verify link status on connected equipment and confirm negotiated 25GbE speed in the device management interface. No external power or transceiver modules are required; the cable functions as a fixed electrical link. For proper operation, use with ports that explicitly support passive DACs and verify compatibility with the switch or server vendor if required.
Usage recommendations
Route the cable within rack cable management to avoid sharp bends and excessive stress; maintain the manufacturer's minimum bend radius. Use the 2 m length for intra-rack or adjacent-rack links; for longer distances select active DAC or fiber-optic transceivers. Inspect connectors for contaminants before insertion and power-cycle equipment only if link issues persist after verifying physical connections.
