Mikrotik S-RJ01 RJ45 SFP Copper Module Up to 1.25 Gb/s bi-directional

The MikroTik S-RJ01 is an RJ45 SFP copper module that brings true Gigabit Ethernet connectivity to any standard SFP port without requiring fiber infrastructure. Supporting 10/100/1000 Mbps auto-negotiation and delivering up to 1.25 Gb/s bi-directional data links over standard unshielded twisted-pair cabling at distances up to 100 meters, the S-RJ01 is an elegant and cost-effective solution for network engineers who need to leverage existing copper cabling plant within SFP-equipped MikroTik routers and switches. Hot-pluggable and compliant with both IEEE 802.3 and SFP MSA standards, the module integrates seamlessly into production environments with minimal disruption. Originally shipped with the CCR1016-12S-1S+, it is now available for separate purchase, making it an accessible expansion option for a wide range of MikroTik platforms.

Key features & benefits

• Up to 1.25 Gb/s Bi-Directional Throughput — Delivers full Gigabit-class bandwidth in both directions simultaneously, ensuring high-performance data transfer across copper links in demanding network environments.
• 100-Meter Reach over Unshielded Cabling — Supports transmission distances up to 100 meters over standard unshielded twisted-pair cable, making it practical for intra-rack, inter-rack, and cross-room deployments without fiber.
• 10/100/1000M Copper RJ45 Interface — The familiar RJ45 connector allows direct termination to standard patch cables and switch ports, simplifying integration into existing copper infrastructure.
• Hot-Pluggable SFP Form Factor — Conforms to the SFP MSA mechanical standard, enabling live insertion and removal without powering down the host device — critical for maintaining uptime in production networks.
• IEEE 802.3 and SFP MSA Compliance — Adherence to IEEE Std 802.3TM-2002 and the SFP Multi-Source Agreement ensures broad interoperability with standards-compliant SFP ports across MikroTik platforms.
• Physical Layer Access via 2-Wire Serial Bus — Provides access to the physical layer integrated circuit through a 2-wire serial bus interface, enabling advanced diagnostics and monitoring capabilities on supported platforms.
• Extended Operating Temperature Range — Rated for operation from 0°C to +85°C, the S-RJ01 can be reliably deployed in environments where temperature control is not guaranteed, such as industrial or outdoor enclosures.
• RoHS Compliant — Manufactured in accordance with RoHS directives, reflecting a commitment to reducing hazardous substances in network hardware throughout its lifecycle.
• +3.3V Single Power Supply — Operates on a standard +3.3V single supply drawn directly from the host SFP cage, requiring no external power and keeping cabling tidy.
