100G DAC high-speed cable is the preferred solution for short distance interconnection in data centers and high-performance computing.
100G DAC high-speed cable transmits electrical signals, has low power consumption and low cost, and is suitable for high-speed connection between equipment in cabinets.
C-LIGHT 100G DAC direct attach copper cables are designed for high-speed short-distance connections between servers, switches, and computing equipment. By combining the connector assemblies and copper transmission medium into one cable, the solution provides a straightforward way to establish 100Gbps links without deploying separate optical transceivers and fiber patch cords.
The 100G DAC portfolio covers several interface architectures, including 100G SFP112 to SFP112, SFP56-DD to QSFP56, and QSFP28 to QSFP28. Breakout versions are also available for connecting a 100G interface with two 50G ports or four 25G ports.
Depending on the configuration, cable lengths range from 0.5m to 5m. The product family uses different copper gauges, including 26AWG, 28AWG, and 30AWG, according to the cable length and connector configuration.
The 100G DAC series is intended for short-distance interconnection in data centers and high-performance computing environments, where low power consumption, low cost, and efficient equipment-to-equipment connectivity are important considerations.
The product provides 100Gbps direct electrical connectivity for high-bandwidth data center and computing applications.
The portfolio includes SFP112, SFP56-DD, QSFP56, and QSFP28 interface configurations for different generations of 100G equipment.
Native QSFP28-to-QSFP28 configurations provide a direct connection between compatible 100G network ports.
The SFP112-to-SFP112 configuration provides a 100G option for equipment using the newer single-channel SFP112 form factor.
Selected QSFP28 configurations divide a 100G connection into two 50G QSFP28 interfaces for mixed-speed deployments.
The 100G QSFP28-to-4x25G SFP28 configuration enables one 100G port to connect with four 25G interfaces.
Depending on the model, available lengths include 0.5m, 1m, 2m, 3m, and 5m for different short-distance installation requirements.
26AWG, 28AWG, and 30AWG cable options are used across the product portfolio to accommodate different length and mechanical requirements.
100G DAC provides a direct high-speed link between compatible servers and network switches in modern data center environments.
The cable is suitable for HPC infrastructures that require high-bandwidth connections between computing nodes and switching equipment.
C-LIGHT specifies support for InfiniBand NDR, making the 100G DAC suitable for compatible high-performance computing network environments.
QSFP28-based configurations provide a direct copper interconnect option for compatible 100GbE network equipment.
Short copper assemblies can connect nearby 100G switches where the physical distance remains within the supported cable range.
100G DAC can simplify high-speed server access connections by combining the cable and connector assemblies into a single interconnect.
100G-to-50G and 100G-to-25G breakout cables help integrate 100G equipment with lower-speed network interfaces.
The short cable lengths make the product suitable for connections between equipment installed within the same rack or nearby racks.
The DAC architecture is optimized for equipment connections where the physical distance is short enough for direct copper transmission.
Direct electrical transmission avoids the optical conversion components required by optical transceiver-based connections, helping reduce power consumption on short links.
The integrated copper cable design provides an economical alternative for short-distance 100G connections where optical reach is not required.
SFP112, SFP56-DD, QSFP56, and QSFP28 options allow the product family to support different 100G equipment architectures.
100G-to-2x50G and 100G-to-4x25G configurations provide practical options for mixed-speed network environments.
With configurations extending from 0.5m to 5m, customers can select a cable length appropriate for their rack layout and equipment placement.
C-LIGHT states that its 100G DAC is compatible with switches from more than 100 brands.
C-LIGHT provides product testing, compatibility support, customized configurations, spot supply, and technical assistance for customer deployments.
