Provides low-latency, low-power, cost-effective links for rack-to-rack or intra-rack connectivity in data centers and enterprise networks.

## Long description

CBO SFP28 Passive DAC Cable SFP28-DAC-2M is a 2 metre twinax copper direct attach cable engineered for short‑reach 25GbE connections between SFP28 ports. The passive twinax assembly provides a simple, low-latency physical link for interconnecting switches, routers and servers inside racks or between adjacent racks. Designed for environments that require cost‑effective, low‑power 25 Gigabit Ethernet links, the cable supports direct port‑to‑port connectivity without the need for separate optical transceivers.
Advantages
The passive twinax copper construction yields lower power consumption compared with active optical solutions and eliminates the need for separate transceivers, reducing overall deployment cost. Its 2 metre length is optimized for intra‑rack and short inter‑rack topologies, while the SFP28 form factor ensures compatibility with standard 25GbE SFP28 ports. The cable offers low latency and predictable electrical performance suitable for high‑density, low‑overhead data centre links.
Suitable for
 Direct connections between SFP28 ports in top‑of‑rack switches and adjacent servers
 Rack‑to‑rack connections within short spans in data centres
 25 Gigabit Ethernet uplinks and server interconnects requiring low latency
 High‑density network deployments where cost and power efficiency are priorities
Key specifications
 Interface: SFP28 to SFP28
 Length: 2 metres
 Cable type: Passive twinax copper
 Supported speed: 25 Gigabit Ethernet (25GbE)
 Form factor: SFP28 direct attach copper (DAC)
 Typical use: Short‑reach intra‑rack and adjacent rack connectivity
How to use
Insert each SFP28 connector end into the corresponding SFP28 port on your network devices until the latch engages. Ensure devices are powered down or that hot‑plug procedures recommended by the device vendor are followed to avoid port damage. Confirm link status on both devices and verify speed and duplex settings where applicable. For best results, route the cable to avoid sharp bends and avoid sources of strong electromagnetic interference.
Usage recommendations
Use this passive SFP28 DAC cable for short, direct 25GbE links inside racks or between neighboring racks. Avoid extending beyond the recommended 2 metre span and keep the cable away from high‑temperature zones and tight cable bundles to preserve electrical characteristics and maintain reliable link quality.
