Suitable for high-speed rack-to-rack and top-of-rack links in data centers and enterprise networks.

## Long description

Direct Attach Copper (DAC) cable CBO SFP28-DAC-1M passive copper 1 m 25 Gbps SFP28 is a 1‑metre twinax cable engineered for SFP28 ports and 25 Gbps links. The cable provides a short‑reach, low‑latency electrical connection between compatible switches, network interface cards (NICs) and servers. As a passive DAC it eliminates the need for separate optical transceivers and is intended for rack-to-rack and top-of-rack connections in data centers and enterprise network environments.
Advantages
This passive copper twinax cable delivers 25 Gbps throughput with minimal latency and low power consumption compared with active optical solutions. The fixed 1 m length simplifies cabling in dense rack environments and reduces component count by replacing optical modules. Its direct-attach design supports plug-and-play operation on devices with compatible SFP28 ports and avoids additional fiber patching or transceiver management.
Suitable for
Short‑reach connections between switches within the same rack
Top‑of‑rack (ToR) uplinks to aggregation or core switches
Direct links from servers to NICs or host adapters
High‑density data center cabling where power efficiency and low latency are required
Key specifications
Connector type: SFP28 copper twinax passive
Length: 1 metre
Rated data rate: 25 Gbps
Cable construction: twinax copper suitable for short‑reach interconnects
Latency: minimal electrical transmission latency for short distances
Power: passive operation with no external power required
How to use
Insert each SFP28 connector into the compatible SFP28 ports on the two devices to be connected until the latch engages. Ensure both devices support passive DAC cables and are configured for 25 Gbps operation. Verify link status and speed through the device management interface or CLI. For best signal integrity, avoid sharp bends and keep the cable within its recommended bend radius; secure the cable within the rack to prevent strain on the connectors.
Usage recommendations
Use this cable for short, direct electrical interconnects in controlled data center environments. Confirm compatibility with the specific switch or server models before deployment and keep firmware or driver software up to date to ensure optimal link negotiation and performance.
