Designed for 25Gbps SFP28 ports to provide a low-latency, short-reach interconnect between switches, servers, and NICs. Simple plug-and-play connectivity with metal SFP28 connectors, suitable for data center top-of-rack and server-to-switch links where cost-effective, reliable short-distance cabling is required.

## Long description

Passive 2-meter Direct Attach Copper (DAC) SFP28 cable CBO SFP28-DAC-2M is a short-reach copper interconnect designed for 25Gbps SFP28 ports. The cable provides direct, low-latency connectivity between switches, servers and network interface cards using SFP28 metal connectors. Its 2 m length is intended for top-of-rack and server-to-switch links in data center racks where a cost-effective, reliable copper solution is preferred over optical transceivers for short distances.
Advantages
The DAC SFP28 cable delivers 25Gbps line rate with minimal latency and low power consumption thanks to its passive copper design. Metal SFP28 connectors ensure secure mechanical fit and simplified plug-and-play deployment without additional transceivers or optical modules. The fixed 2 m length reduces clutter in rack environments and provides predictable signal performance for short-distance links, while offering a lower total cost of ownership compared with equivalent active or optical cabling options.
Suitable for
Top-of-rack (ToR) switch to server connections
Server-to-server links within the same rack or adjacent racks
High-density 25Gbps switch clusters in data centers
Short-reach uplinks where low latency and low power are required
Key specifications
Interface: SFP28 to SFP28 copper direct attach
Rated data rate: 25 Gbps per lane (25Gbps link)
Length: 2 meters
Cable type: Passive copper twinax
Connector type: Metal SFP28 plug housings
Typical use: Short-reach rack-level interconnects
How to use
Install the DAC SFP28 cable by firmly inserting each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until the connector latch engages. No additional configuration is typically required; devices will detect the physical link and negotiate the 25Gbps connection if both endpoints support SFP28 and the required speed. For best results, route the cable within the rack to avoid sharp bends and mechanical stress on the connectors, and verify link status via your network equipment management interface after installation.
Usage recommendations
Use this 2 m passive DAC cable for short-distance, high-bandwidth connections inside racks or between adjacent racks. Do not exceed recommended bend radius, avoid exposure to excessive heat or moisture, and ensure both endpoints support 25Gbps SFP28 passive DAC connections for compatibility.
