MikroTik S+RJ10

Description
Description
The MikroTik S+RJ10 is a relatively simple to understand device. One end plugs into a standard SFP+ port on a switch, and the other has a RJ45 port. Essentially, the S+RJ10 converts a SFP+ port into a standard copper networking port.

It goes a bit beyond a standard RJ45 in this case. These types of adapters have been available for years going from a 10GbE SFP+ port to a 1GbE RJ45 port. Even only 3 years ago major vendors were selling SFP+ to 10Gbase-T adapters for thousands of dollars. Power consumption and heat are so much higher with 10GbaseT, and the SFP+ module is so compact, that that was a major concern. Now, using the Marvell 88X3310P, we have solutions like the S+RJ10 that can run at only 2.4W on a 30m 10Gbase-T link and therefore fit in many switches.
