Direct Attach Twinax Cables (DACs)

DAC is direct attach copper cable assemblies with hot swappable transceiver modules like as QSFP28, QSFP+, SFP28, SFP+, XFP. It provides a lower cost, high density interconnects solution alternative for high speed interconnects from 10G to 200G to fiber optics transceivers.

COMNEN provides customization service of a wide range of DAC products for 0.5m to 10m lengths and in QSFP28,QSFP+, SFP28, SFP+, XFP form factors, such as 10G SFP+ DAC Cables; 25G SFP28 DAC Cables; 40G QSFP+ DAC Cables; 40G QSFP+ to SFP+ Cables; 50G QSFP+ DAC Cables; 50G QSFP+ to SFP+ Cables; 56G QSFP+ DAC Cables; 56G QSFP+ to SFP+ Cables; 100G QSFP28 DAC Cables; 100G QSFP28 to SFP28 DAC Cables; 200G QSFP56 DAC cable, SAS Cables.

EEPROM technique has been used to ensure the DACs are compatible with different brands on the original switches and routers, and 100% TDR&VNA test passed. They are also fully tested in SI testing lab and reliability lab, to ensure optimal signal integrity and the best end-to-end performance.
