SFP28 Direct Attach Cables (25G DAC ) are compliant with SFF-8432 and SFF-8402 specifications. Various choices of wire gauge are available from 30 to 26 AWG with various choices of cable length (up to 5m). The SFP28 passive direct attach copper cable assemblies are high-performance, cost-effective I/O solutions for 25G Ethernet. SFP28 copper cables allow hardware manufacturers to achieve high port density, configurability, and utilization at a very low direct attach copper cable sfp+ cost and reduced power budget of passive copper cable.
As a professional optical transceiver manufacturer, we also provide a range of optical transceivers, such as 400g optical transceiver, 100g optical transceivers, 40g qsfp+aatransceiver, 25g sfp28 transceiver, 10g sfp+ transceiver, sfp device, etc.

25G DAC is a DAC whose actual transmission rate can reach 25G, and 25G DAC can transmit at a distance of less than 7 meters. 25G DACs are generally used in 25G short-distance transmission networks, plugged into 25G optical ports, and connected to another 25G optical port in the same rack or adjacent racks.
