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.
The cable provides up to 25Gbps connectivity for modern data center and high-speed networking applications.
The native configuration uses SFP28 connectors on both ends for direct connection between compatible 25G network ports.
The product supports 25G, 10G, and 1G data rates, providing flexibility for networks containing multiple Ethernet speeds.
The product family supports transmission distances from 0.5m to 30m, providing more reach options than typical short rack-level DAC deployments.
Different AWG constructions are used across the cable length range, including 30AWG, 28AWG, and 26AWG configurations.
The cable follows the SFP28 MSA packaging specification for compatibility with suitable SFP28-based network equipment.
The communication protocol specified by C-LIGHT complies with IEEE 802.3ba for supported applications.
The 25G DAC is designed for data centers, 5G networks, 25G Ethernet, Fibre Channel, and other high-speed connectivity scenarios.
25G SFP28 DAC provides a direct copper connection for servers and switches deployed in 25GbE data center networks.
The product can be deployed in 5G-related network environments where high-speed short-distance equipment connections are required.
25G DAC can connect SFP28 server network interfaces with compatible switches, providing high-bandwidth connectivity for modern data center systems.
SFP28 DAC assemblies can be used between compatible switches when the physical connection falls within the supported copper transmission range.
The product family can be applied to suitable Fibre Channel environments requiring high-speed direct copper connections.
Support for 1G, 10G, and 25G operation allows the cable to fit network environments where multiple data rates are present.
High-speed server and storage infrastructures can use 25G DAC for direct connections between compatible network interfaces.
The availability of configurations extending to 30m provides additional flexibility for equipment that cannot be positioned within a very short rack distance.
Support for 1G, 10G, and 25G allows the 25G DAC family to accommodate different network speeds without limiting deployment to a single data rate.
With the product family covering 0.5m to 30m, customers have more flexibility when planning connections between equipment at different physical locations.
The SFP28-to-SFP28 construction provides a straightforward connection method for equipment already equipped with SFP28 ports.
For suitable short-distance applications, direct copper connectivity can provide a practical alternative to deploying separate optical modules and fiber cabling.
The direct copper transmission architecture is suitable for applications where short-distance connectivity and low latency are important.
C-LIGHT states that its 25G DAC high-speed cable is compatible with more than 100 brands of switches.
C-LIGHT states that products undergo initial testing, final testing, and factory inspection as part of its quality-control process.
C-LIGHT provides spot supply and customized solutions together with technical support and after-sales service for customer deployments.
A 25G DAC is a direct attach copper cable designed to provide high-speed connectivity between compatible SFP28 network interfaces.
