## Long description

CBO SFP28-DAC-1M is a 1-meter passive copper direct-attach cable designed for direct connection between SFP28 ports. The cable provides a fixed-length, low-latency physical link for 25GbE and compatible SFP28 interfaces without requiring separate optical transceivers. Intended for short-reach rack-to-rack or within-rack connections, the cable simplifies cabling, reduces power consumption and equipment cost, and supports reliable high-speed data transmission in data center and enterprise switching environments.
Advantages
The passive copper construction delivers predictable latency and low heat generation compared with active modules, while the 1 m fixed length minimizes signal degradation for short-distance links. As a direct-attach solution, this cable eliminates the need for additional SFP28 transceivers, lowering both capital and operational expenses. Its plug-and-play form factor offers straightforward installation and immediate compatibility with compliant SFP28 ports, enabling stable 25GbE links for server, switch and storage interconnects.
Suitable for
 Short-reach connections between switches within the same rack
 Interconnects between adjacent racks in a data center row
 Server-to-switch or top-of-rack switch connections
 High-density environments where reduced power per port is required
Key specifications
 Interface type: SFP28 to SFP28 compatible
 Cable type: passive twinax copper
 Length: 1 meter
 Data rate support: up to 25 Gbit/s per lane (25GbE)
 Form factor: direct-attach cable (fixed-length, pluggable)
 Typical use case: short-reach rack-to-rack or within-rack links
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected until the latch engages. Confirm link status through device LEDs or management interfaces and verify negotiated speed is 25GbE or the expected compatible rate. For best performance, route the cable to avoid sharp bends and keep it clear of sources of electromagnetic interference. When removing the cable, press the connector latch and pull straight out to avoid stressing the port.
Usage recommendations
Use this 1 m passive DAC for short-distance, high-density connections where cost and power efficiency are priorities. Validate port compatibility with SFP28 before deployment and avoid extending beyond the recommended reach; for longer distances consider optical transceivers and fiber cables.
