10G DAC connection is usually linked between the equipment with 10G SFP+ ports. However, some times, we also meet the situation that we need to connect 2 equipment, one supporting 10G SFP+ ports, and the other supporting only 10G XFP ports. Considering it is a short distance connection and the advantages of DAC cables, that is lower cost and lower power consumption, the 10G SFP+ to XFP DAC cables would be a better solution compared to building connections using 10G optical SFP+ and XFP transceivers. AscentOptics can offer the 10G SFP+ to XFP DAC cables, reach from 1m to 3m. Providing customers with more flexible 10G connection option between the equipment with different optical ports .
