## Summary description

CBO SFP28-DAC-0.5M is a 0.5 m passive direct-attach copper (DAC) cable with SFP28 connectors designed for 25Gbps short-reach links. It provides a cost-effective, low-latency connection between SFP28 ports on switches, servers or NICs without external transceivers. Suitable for data center top-of-rack, server interconnects and storage networks requiring high-density cabling.

## Long description

BlueOptics Direct-Attach Copper DAC Cable CBO SFP28-DAC-0.5M is a 0.5 m passive SFP28 twinax cable engineered for 25 Gbps short-reach connections. The compact, factory-terminated assembly features SFP28 connectors on both ends and is intended for direct attachment between compatible SFP28 ports on switches, servers and network interface cards. By eliminating separate optical transceivers, this cable offers a space-efficient and low-latency option for high-density data center top-of-rack and server-to-switch links.
Advantages
The passive SFP28 direct-attach copper design provides low latency and low power consumption compared with active or optical solutions. With a fixed 0.5 m length and robust SFP28 connectors, the cable simplifies rack wiring and reduces the need for additional transceivers, lowering overall deployment cost. The twinax copper construction supports reliable 25 Gbps signaling for short-reach links and is suitable for dense port environments where cable management and airflow are critical.
Suitable for
 Top-of-rack switch to server connections in data centers
 Server-to-server or server-to-NIC interconnects within the same rack
 Storage network links requiring 25 Gbps short-reach connectivity
 High-density switch deployments with limited rack space
Key specifications
 Connector type: SFP28 on both ends
 Transmission rate: 25 Gbps
 Cable length: 0.5 m (fixed)
 Cable type: Passive twinax copper (direct-attach)
 Application: Short-reach data center links and server interconnects
 Form factor: Low-profile SFP28 compatible for high-density ports
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until the retention latch engages. Ensure both devices support passive SFP28 direct-attach copper cabling and that firmware or port settings permit 25 Gbps operation. Use the fixed 0.5 m length to route the cable inside the rack, avoiding sharp bends and excessive strain on the connectors. No additional transceivers or external power are required for operation.
Usage recommendations
For reliable performance, use this 0.5 m passive SFP28 DAC within the same rack or adjacent racks where short-reach connections are specified. Verify device compatibility with passive SFP28 twinax cables and follow equipment vendor guidelines for supported cable assemblies. Store and install the cable in a clean environment, protect connector ends from contamination, and avoid tight bending radii to maintain signal integrity.
