## Summary description

MikroTik S-RJ01 is a network switch module with a single Gigabit Ethernet RJ-45 port supporting 1000 Mbps LAN speeds and a data transfer capability of up to 1.25 Gbit/s. Designed for integration into compatible MikroTik equipment, it operates in temperatures from 0 to 85 °C and supports short-distance copper connections up to 0.1 km. Suitable for expanding port capacity in switches, routers or patch panels in small networks and rack systems.

## Long description

S-RJ01 is an RJ45 SFP 10/100/1000M copper module designed for compatibility with most Gigabit SFP ports on switches, routers and other network devices. The module provides a compact hot-pluggable SFP form factor with a standard RJ-45 connector and supports up to 1.25 Gb/s bi-directional links over copper cabling for short-range Ethernet connections.
Advantages
The S-RJ01 offers a simple way to add copper Ethernet connectivity to devices with SFP slots without modifying hardware. It supports a standard 3.3V single power supply, complies with IEEE 802.3 and SFP MSA specifications, and allows access to the physical layer IC through a 2-wire serial bus. The module is RoHS compliant and rated for extended case temperatures, enabling reliable operation in a range of environments.
Key specifications
 Data rate: up to 1.25 Gb/s bi-directional
 Media: unshielded twisted pair (UTP), up to 100 m
 Connector: RJ-45
 Standards: IEEE Std 802.3TM-2002, SFP MSA compliant
 Power supply: +3.3 V single power
 Temperature range (case): 0°C to +85°C
 Form factor: Hot-pluggable SFP footprint
 Management: access to PHY via 2-wire serial bus
 Environmental: RoHS compliant
How to use
Insert the S-RJ01 module into a compatible SFP port on the network device until it seats firmly; it is hot-pluggable so no shutdown is required on most equipment. Connect an RJ-45 UTP cable to the module and ensure link LEDs or device diagnostics indicate an active connection. Configure the device port as needed for speed and duplex settings; the module negotiates up to Gigabit speeds over copper. For management, access the physical layer IC via the two-wire serial interface if supported by the host.
Recommendations
Use Category 5e or better UTP cable for reliable Gigabit operation up to 100 m, verify compatibility with your device’s SFP port, and observe the specified operating temperature range (0°C to +85°C) to ensure stable performance.
