Cudy Fiber SFP Module SFP Slot to 2.5GbE RJ45 SM25G

Unlock high-speed multi-gigabit connectivity with the Cudy SM25G SFP to 2.5GbE RJ45 Copper Transceiver Module. Designed for versatility and robust performance, this compact transceiver transforms standard optical SFP slots on your switches, routers, or media converters into a high-speed RJ45 Ethernet port, allowing you to bridge fiber-ready hardware with standard Cat5e or Cat6 copper cables.

High-Speed Multi-Gigabit Networking

Equipped with intelligent auto-negotiation, the Cudy SM25G seamlessly accommodates 10Mbps, 100Mbps, 1Gbps, and 2.5Gbps connections. This makes it the ideal upgrade for linking high-throughput devices—such as Wi-Fi 6/7 access points, 2.5G network-attached storage (NAS) devices, and performance workstations—directly to your network backbone without needing expensive fiber cabling.

Plug-and-Play Simplicity

With its hot-pluggable SFP form factor, the module can be installed or replaced without powering down your switch, minimizing costly network downtime. Featuring durable metallic housing for optimized heat dissipation and low power consumption, it ensures long-term stability and reliability in demanding office and home lab environments.
