The MikroTik S+RJ10 is a unique 10 Gigabit SFP+ transceiver module that converts an SFP+ port on a switch or router into a standard copper RJ45 Ethernet port.¹ This allows you to achieve high-speed 10 Gbps connectivity over a regular twisted-pair network cable, eliminating the need for a fiber optic connection.²

Key Features and Specifications

• Data Rate: The S+RJ10 is a multi-gigabit module that can operate at speeds of 10M, 100M, 1G, 2.5G, 5G, and 10G.³ It auto-negotiates the highest possible speed with the connected device.

   

• Media Type: It is designed to work with standard copper Ethernet cables, specifically Cat6A/Cat7 for a full 10 Gbps connection up to 30 meters.⁴ At lower speeds, it can work over longer distances with Cat5e or Cat6 cabling.

   

• Connector: It has a single RJ45 port.⁵

   

• Power Consumption & Heat: The module's power consumption is a key consideration.⁶ At 10G speeds, it can consume up to 2.4W and generate significant heat.⁷ MikroTik recommends using this module in switches with active cooling.⁸ If used in a passively cooled device, or if multiple modules are installed side-by-side, additional cooling may be required to prevent overheating.⁹

   

• Compatibility: The S+RJ10 is designed to be fully compatible with any MikroTik device that has an SFP+ port.¹⁰ It also supports features like Jumbo Frames (up to 10218 Bytes) and DDM (Digital Diagnostics Monitoring) for supply voltage and temperature in its latest revisions.¹¹

   

• Application: This module is an ideal solution for upgrading existing network devices to 10G speeds without a complete overhaul of the network cabling.¹² It's perfect for short-distance connections, such as linking a server or NAS with a 10G Ethernet port to a fiber-based SFP+ switch.¹³
