## Summary description

Passive copper DAC cable CBO SFP28-DAC-1M is a 1 m direct-attach cable with SFP28 connectors on both ends. Designed for short-reach 25GbE interconnects between switches, servers or NICs, it provides low-latency, low-power connectivity without transceivers. Ideal for data center top-of-rack links and high-density server racks where cost-effective direct connections are required.

## Long description

Passive copper DAC cable CBO SFP28-DAC-1M is a 1 m direct-attach twinax cable terminated with SFP28 connectors on both ends. It is built for short-reach 25GbE interconnects between switches, servers or NICs and removes the need for separate optical transceivers by providing a direct electrical link. The compact, low-profile design suits high-density environments and offers a cost-effective, low-power option for data centre top-of-rack links and adjacent rack connections.
Advantages
The cable delivers low latency and reduced power consumption compared with optical solutions because it is a passive copper twinax assembly. Its 1 m length minimises signal attenuation for short connections and the SFP28 connector compatibility ensures straightforward plug-and-play installation into standard SFP28 ports. The assembled cable supports stable 25 Gigabit Ethernet connectivity while simplifying inventory and lowering per-port cost in dense deployments.
Suitable for
 Top-of-rack switch-to-switch or switch-to-server 25GbE links
 High-density server racks where short copper interconnects are required
 Connections between NICs and adjacent switches or patch panels
 Environments seeking low-power, low-latency direct-attached links
Key specifications
 Interface: SFP28 to SFP28
 Length: 1 metre
 Type: Passive copper direct-attach (twinax)
 Data rate support: 25 Gigabit Ethernet
 Form factor: SFP28 compatible plugs on both ends
 Typical use range: short-reach / adjacent rack or same-rack connections
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be interconnected, ensuring the latch engages. No separate transceivers, optical modules or cable adapters are required. After physical insertion, verify link status and speed on the connected devices and configure network settings as needed. For multiport switch deployments, route the cable to avoid tight bends and maintain manufacturer-recommended bend radii to preserve signal integrity.
Usage recommendations
Use this 1 m passive DAC cable for direct short-range 25GbE connections in rack-to-rack or intra-rack setups. Avoid exceeding the recommended bend radius, ensure proper port seating, and select this passive twinax option where power efficiency and cost per port are priorities over longer-distance reach.
