## Long description

CBO SFP28-DAC-0.5M is a 0.5 meter passive direct-attach copper cable engineered for SFP28 ports and 25Gb/s links. The cable provides a fixed, low-latency connection between servers, switches and network interface cards (NICs) over short distances, offering a compact, cost-effective alternative to optical transceivers where direct electrical connectivity is suitable. Its passive design operates without external power and is intended for high-density rack environments and short-reach top-of-rack interconnects.
Advantages
The passive SFP28 DAC delivers predictable latency and consistent signal integrity for short-reach 25Gb/s connections while reducing power consumption compared with active or optical modules. Its one-piece copper assembly simplifies installation and removal in dense port deployments and eliminates the need for separate fiber patching. The fixed-length construction minimizes connector variability and helps maintain stable link performance in test setups and production racks.
Suitable for
Top-of-rack switch to server connections in data centers
Direct links between switches and NICs supporting 25Gb/s
High-density rack deployments where space and port count are critical
Lab and test environments requiring repeatable short-range links
Key specifications
Connector type: SFP28 direct-attach copper
Length: 0.5 meter
Data rate: up to 25 Gb/s per lane (compatible with 25Gb/s interfaces)
Construction: passive copper twinax assembly
Typical use: short-reach electrical interconnects for racks and servers
Form factor: SFP28 pluggable module style for compatible ports
How to use
Insert the SFP28 connectors into compatible SFP28 ports on each device until the latch engages. Ensure both ends are seated fully and that the connected devices are powered and configured for 25Gb/s operation. No additional power or configuration on the cable itself is required. For safe removal, unlatch the connector and withdraw it straight out to avoid stressing the port. Verify link status on both devices after installation to confirm proper operation.
Usage recommendations
Use the cable for distances within typical short-reach specifications, avoiding runs longer than the manufacturer-recommended length to prevent signal degradation. Maintain adequate airflow around high-density ports and avoid excessive bending or kinking of the cable near the connector. When used in multi-vendor environments, confirm compatibility with the switch or NIC firmware and port settings before large-scale deployment.
