Cudy SFP to RJ45 Gigabit Ethernet Module 100m

The Cudy SM220 SFP-T 10/100/1000Mbps RJ45 Ethernet Module delivers dependable and high-speed wired network connections for enterprise, SMB, and advanced home networking environments. Fully compliant with the SFP Multi-Source Agreement (MSA), this copper transceiver supports Gigabit Ethernet and 10/100/1000BASE-T standards as defined in IEEE 802.3, ensuring seamless compatibility with a wide range of switches, routers, and network interface cards. Whether upgrading infrastructure or expanding connectivity, the SM220 offers a cost-effective and flexible networking solution.

Engineered for efficiency, the hot-pluggable SFP footprint allows quick installation or replacement without service interruptions. Consuming just 1.05W typical power, the SM220 helps reduce energy costs while maintaining optimal performance. Its compact RJ45 connector assembly and fully metal enclosure not only enhance durability but also reduce electromagnetic interference (EMI) for stable and interference-free connections.

The SM220 supports bi-directional data rates up to 1.25Gbps over Cat 5 or better cabling, with 10/100/1000BASE-T operation in host systems equipped with a 1000BASE-X interface. Using the SFPs RX_LOS pin for link indication, it provides reliable connectivity feedback to network administrators. The robust electrical design ensures minimal latency and consistent throughput, making it ideal for bandwidth-intensive tasks like VoIP, video conferencing, and large-scale file transfers.

With an operating temperature range of 0°C to +70°C, the Cudy SM220 is suited for diverse networking environments, from climate-controlled server rooms to active office floors. Its RoHS-compliant, lead-free construction ensures eco-friendly operation, while the single +3.3V power supply simplifies integration into existing setups. Perfect for upgrading to gigabit speeds or enhancing network flexibility, this module offers a dependable and scalable solution for modern networking needs.
