## Summary description

Passive SFP28 DAC copper cable CBO SFP28-DAC-1M, 1 meter length, for direct connection between SFP28 ports supporting 25GbE. Designed for short-reach interconnects in switches, routers and servers where low latency and power efficiency are needed. Plug-and-play solution with fixed connectors for simplified rack deployments and reduced cable management complexity.

## Long description

Passive SFP28 DAC copper cable CBO SFP28-DAC-1M is a 1 metre direct-attach copper cable engineered for short-reach 25GbE interconnects between SFP28 ports. The cable provides a fixed, low-latency physical link for switches, routers and servers where power efficiency and space-saving rack deployments are priorities. As a passive DAC it requires no additional power or transceivers and offers a plug-and-play connection with fixed SFP28 connectors for simplified installation and predictable performance in dense network environments.
Advantages
This passive SFP28 DAC cable delivers low latency and minimal power consumption compared with active or optical alternatives, while providing stable electrical performance over a 1 metre reach. The fixed SFP28 connectors reduce installation time and lower the risk of connector mismatch. The copper construction enables reliable signal integrity for short distances and avoids the need for separate transceiver modules, helping to reduce overall hardware and operational costs.
Suitable for
Short-reach 25GbE links between top-of-rack switches
Direct server-to-switch connections in data centre racks
Interconnects inside rack-mounted network equipment
High-density switch fabrics where low latency is required
Key specifications
Form factor: SFP28 direct attach copper (DAC)
Length: 1 metre
Data rate support: 25 Gigabit Ethernet (25GbE)
Connector type: fixed SFP28 male connectors
Operating mode: passive (no active electronics)
Typical use case: short-reach interconnects within racks
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. No additional transceivers or power supplies are required. Ensure both devices support 25GbE over passive copper DACs and that firmware and port configurations are set to the required link speed. Avoid tight bends and secure the cable to reduce strain on the connectors during rack installation.
Usage recommendations
Use this 1 m passive SFP28 DAC for short intra-rack runs where low latency and power efficiency are important. Verify compatibility with your switch or server vendor documentation for supported passive DACs, and maintain minimum bend radius and strain relief to preserve signal integrity and connector life.
