## Summary description

Direct attach copper (DAC) CBO BlueLAN SFP28-DAC-2M is a 2-meter passive SFP28 cable designed for 25GbE SFP28 ports. It provides a fixed, low-latency connection between compatible switches, NICs or servers without separate transceivers. Ideal for short-reach interconnects in racks or adjacent cabinets, it simplifies cabling and reduces power consumption compared with optical modules.

## Long description

CBO DAC SFP28 BlueLAN SFP28-DAC-2M is a 2‑metre passive copper direct attach cable engineered for 25GbE SFP28 ports. The cable provides a fixed electrical connection between compatible switches, network interface cards and servers without the need for separate optical transceivers. Its passive design reduces power consumption and offers predictable, low-latency performance for short-reach interconnects inside racks or between adjacent cabinets.
Advantages
The passive copper construction delivers low latency and stable signal integrity for short distances while eliminating the additional power and cost of active transceivers. This SFP28 DAC is pre-terminated and hot-pluggable, simplifying installation and minimizing cable management complexity. Using a single integrated assembly removes compatibility requirements for separate transceiver modules and fibers, streamlining procurement and deployment.
Suitable for
Top-of-rack and end-of-row switch interconnects in data centres
Server-to-switch connections for high-throughput compute nodes
High-performance networking within single cabinet or between adjacent cabinets
Short-reach links where low latency and low power are priorities
Key specifications
Connector type: SFP28 on both ends
Cable type: Passive twinax copper assembly
Length: 2 metres
Data rate: supports 25 Gigabit Ethernet
Form factor: direct attach cable (fixed, non-removable transceiver assembly)
Power: passive design with no active electronics in-line (lower power consumption vs optical modules)
Latency: low, fixed electrical path suitable for latency-sensitive applications
How to use
Insert each SFP28 connector into a compatible SFP28 port on the devices to be linked, ensuring the latch engages and the connectors are fully seated. The cable is hot-pluggable and requires no additional configuration beyond standard network interface and switch settings. Verify link status and negotiated speed on both endpoints after insertion. For best results, route the cable to avoid excessive bending and mechanical strain at the connector boots.
Usage recommendations
Use this 2m passive SFP28 DAC for short-distance, high-bandwidth connections inside racks or between adjacent cabinets. Confirm device compatibility with SFP28 passive DAC assemblies and observe manufacturer guidelines for port settings and firmware compatibility to ensure optimal link performance.
