Covering 10G, 25G, 40G, 100G, 200G, and 400G applications, our cable assemblies support QSFP28, QSFP-DD, SFP28, and OSFP interface types. Passive DACs are ideal for short-range, low-power environments, while AOCs and AECs offer extended reach with active signal conditioning. Volex is a leading manufacturer and supplier of Direct Attach Copper (DAC) cables The Volex DAC cable product family includes cable assemblies with Small Form-factor Pluggable (SFP), Quad Small Form-factor Pluggable (QSFP), and Octal Small Form-factor Pluggable (OSFP) single and double density. Lumulus Passive Direct Attach Cables (DACs) offer high-speed, low-power, and cost-effective connectivity for intra-rack data center applications. Supporting SFP, QSFP, DSFP, and OSFP form factors with data rates up to 800G, they feature advanced Twinax technology for lightweight and flexible. 10Gtek® direct attach cable (DAC) is a twinax copper cable assembly. With the features of the low cost, low power consumption and low latency, it is an alternative to optical transceivers for short reach links in high-speed interconnect applications such as Data Center, HPC and enterprise network. High-speed I/O passive cable assemblies that can deliver data rates as high as 400 Gbps with a variety of lengths or customized options for greater design flexibility. The main applications cover.
