We are releasing new direct attach cables that support not only SFP 1G and SFP+ 10G, but also the 25G SFP28 standard! With the new direct attach cables you get more features for the same price!
This is highly cost-effective way to connect two SFP/SFP+/SFP28 devices (for example two units of our new CCR2004-1G-12S+2XS) for very short distances, within racks and across adjacent racks.
They provide a low cost, low power and low latency interconnect solution for 25-Gigabit Ethernet, Fiber Channel and other industry standards, and are direct attached compliant and fully conform to the SFP+ MSA specifications.
