    25G DAC Direct Attach Copper Cable Overview

    C-LIGHT 25G DAC direct attach copper cables are designed for high-speed short-distance connections between SFP28-equipped servers, switches, storage systems, and other network devices. The integrated copper cable assembly combines the electrical transmission medium and SFP28 connectors into a single interconnect for straightforward equipment-to-equipment deployment.

    The 25G DAC series supports 25G, 10G, and 1G data rates, giving the cable additional flexibility in multi-rate network environments. This makes the product suitable not only for dedicated 25G Ethernet links, but also for infrastructure where different generations of Ethernet equipment need to operate within the same network.

    C-LIGHT provides 25G SFP28-to-SFP28 DAC configurations with transmission distances ranging from 0.5m to 30m. The available cable construction varies according to length, with different AWG options used to meet the requirements of short and extended copper connections.

    The 25G DAC family is primarily intended for data centers, 5G networks, 25G Ethernet, Fibre Channel, and other high-speed networking environments where direct copper connectivity can provide a practical alternative to optical interconnection.

    25G DAC Direct Attach Copper Cable Key Features

    25Gbps High-Speed Transmission

    The cable provides up to 25Gbps connectivity for modern data center and high-speed networking applications.

    SFP28 to SFP28 Design

    The native configuration uses SFP28 connectors on both ends for direct connection between compatible 25G network ports.

    1G/10G/25G Multi-Rate Support

    The product supports 25G, 10G, and 1G data rates, providing flexibility for networks containing multiple Ethernet speeds.

    Extended Copper Reach

    The product family supports transmission distances from 0.5m to 30m, providing more reach options than typical short rack-level DAC deployments.

    Multiple Cable Gauges

    Different AWG constructions are used across the cable length range, including 30AWG, 28AWG, and 26AWG configurations.

    SFP28 MSA Packaging

    The cable follows the SFP28 MSA packaging specification for compatibility with suitable SFP28-based network equipment.

    IEEE 802.3ba Protocol

    The communication protocol specified by C-LIGHT complies with IEEE 802.3ba for supported applications.

    Multiple Network Environments

    The 25G DAC is designed for data centers, 5G networks, 25G Ethernet, Fibre Channel, and other high-speed connectivity scenarios.

    25G DAC Direct Attach Copper Cable Applications

    25G Ethernet Networks

    25G SFP28 DAC provides a direct copper connection for servers and switches deployed in 25GbE data center networks.

    5G Network Infrastructure

    The product can be deployed in 5G-related network environments where high-speed short-distance equipment connections are required.

    Data Center Server Links

    25G DAC can connect SFP28 server network interfaces with compatible switches, providing high-bandwidth connectivity for modern data center systems.

    Switch-to-Switch Connections

    SFP28 DAC assemblies can be used between compatible switches when the physical connection falls within the supported copper transmission range.

    Fibre Channel Networks

    The product family can be applied to suitable Fibre Channel environments requiring high-speed direct copper connections.

    Multi-Rate Ethernet Infrastructure

    Support for 1G, 10G, and 25G operation allows the cable to fit network environments where multiple data rates are present.

    Storage and Computing Systems

    High-speed server and storage infrastructures can use 25G DAC for direct connections between compatible network interfaces.

    Longer Rack and Row Connections
