This unique module is an existing product with SFP + port, delivering speeds of up to 10 Gbps with the standard twisted-pair cable and expanding the potential for fast connections. With active cooling features with SFP + ports, MikroTik devices are now available without optical fiber installation. Simply plug in the S+RJ10 to upgrade your network to 10Gbps, ready for the next generation RJ45 hardware. The S+RJ10 module is also supported by passive cooling devices, but additional cooling may be required. The new revision of the S+RJ10 has some improvements: - supports jumbo frames up to 10218 bytes. - Link speed report is fixed - actual link speeds listed in interface menu. Formerly 100M/1G/2.5G/5G link speeds were not reported correctly; - DDM monitoring (supply voltage, module temperature) is now supported.
