Cudy SM220 SFP-T 10/100/1000Mbps RJ45 Ethernet module

Upgrading network infrastructure often hits a wall when legacy copper cabling meets modern fiber-optic switches. The Cudy SM220 SFP-T module bridges that gap, converting an SFP slot into a Gigabit RJ45 port so you can connect standard Cat5e/Cat6 cables directly to fiber switches, media converters, or routers. No need to rip out existing copper runs or buy new switches—just plug in this hot-swappable transceiver and extend your network up to 100 meters over twisted pair.

Who is it for

IT administrators, system integrators, and small-to-medium businesses that operate mixed copper and fiber networks. If you have a switch with empty SFP slots and need to link copper-based devices like IP cameras, access points, or workstations, this module delivers instant compatibility without costly hardware replacements.

Main features

• Converts an SFP slot to a 10/100/1000 Mbps RJ45 copper port
• Supports auto-negotiation for speed and duplex, ensuring seamless link establishment
• Hot-pluggable design allows insertion and removal without powering down the switch
• Digital Diagnostic Monitoring (DDM/DOM) provides real-time monitoring of temperature, voltage, and optical power
• MSA compliant for broad compatibility with Cisco, Ubiquiti, MikroTik, TP-Link, Netgear, D-Link, and other major brands
• Zinc alloy housing ensures durability and effective heat dissipation
• Low power consumption of less than 1.2 W reduces energy costs and thermal load

Tips

Before installation, verify that your switch or router supports SFP copper modules and auto-negotiation. For best performance, use Cat6 or higher cabling for Gigabit speeds over longer distances. The module is plug-and-play, but always check for firmware updates on your network equipment to ensure full DDM functionality.
