## Summary description

Passive copper direct attach cable (DAC) CBO SFP28-DAC-0.5M, 0.5 m length, designed for SFP28 ports. Provides a short-reach wired connection between compatible network devices such as switches, servers and NICs. Ideal for high-speed 25GbE interconnects in racks and data centers where a reliable, low-latency link with minimal power consumption is required.

## Long description

The CBO SFP28-DAC-0.5M Passive Copper DAC cable 0.5 m for SFP28 is a short-reach direct-attach copper cable engineered for 25 Gigabit Ethernet links. With a compact 0.5 m length and SFP28-compatible terminations, this passive DAC provides a wired connection between switches, servers and network interface cards (NICs) where low latency and minimal power consumption are priorities. It is intended for rack and cabinet interconnects in data centers and high-density networking environments.
Advantages
This passive copper DAC offers low latency and near-zero protocol overhead due to its direct electrical connection. The fixed 0.5 m length reduces clutter and crosstalk in dense rack deployments while eliminating the need for separate transceivers and fiber patch cords. Passive operation means no additional power is consumed by the cable itself, simplifying thermal and power planning in server rooms. Compatibility with SFP28 ports ensures straightforward plug-and-play deployment with supported networking equipment.
Suitable for
 Short-distance 25GbE interconnects between switches and servers within racks
 Connections between NICs and top-of-rack or leaf switches
 High-density data center fabric where low latency and low power are required
 Compact cabling runs in server cabinets and network appliances
Key specifications
 Interface type: SFP28-compatible connectors
 Cable type: Passive twinax copper
 Data rate: 25 Gbit/s per link
 Length: 0.5 m
 Typical use: Short-reach intra-rack connections
 Power characteristics: Passive (no active electronics in cable)
How to use
Ensure both devices have SFP28 ports and support passive DAC cables. With equipment powered off or following hot-plug guidelines from the device manufacturers, align and insert each SFP28 connector into the corresponding port until the latch clicks. Verify link status on connected devices and confirm 25GbE negotiation where applicable. For safe removal, follow the host device procedure to avoid link disruption or potential equipment issues.
Usage recommendations
Use this passive DAC for short, direct connections inside racks and cabinets. Avoid routing the cable through pathways where it may be bent sharply; maintain bend radii recommended by the network hardware vendor. Verify compatibility with your switches and NICs prior to deployment and choose passive DACs only for distances within their specified short-reach range.
