Direct-attach copper (dac) cables — high-speed short-range
sfp+ direct attach (10 gbps):
•passive twinax sfp+ dac cables (e.g. models dem-cb100s/300s/700s) deliver 10 gbps speeds with low latency and reduced power usage vs fiber solutions  .
•eliminates the need for separate sfp+ transceivers, providing a cost-effective upgrade to 10 gigabit networking inside racks or between adjacent devices  .
•fully compliant with sfp msa, sff-8431 and ul 94 safety standards; tested for compatibility with d-link switches (e.g. dgs-1510, dxs-3600)
