Mini Industrial 2 Ports Gigabit Media Converter Din Rail Mount Hardened 10/100/1000Mbps Ethernet to SFP Fiber Converter Fiber Switch with 2 RJ45 Port and 2 SFP Port - StarRoute, 2RJ45+2SFP Switch

• 【Auto Sensing 100/1000Base-FX】- The open SFP ports of fiber switch support both 155Mbps and 1.25G SFP module, it means you can use other device with 100M or 1000M fiber port on the other side. 【12~48V Redundant Power Input】- The media converter supports 12~48V dual backup voltage DC input and only need one group of power supply to be connected to work which can ensure long-term stable operation. 【Support Cascade Connection】- The gigabit switch supports cascade connection, and can save fiber cable resources. Besides, users can use SFP modules (single-mode/multi-mode fiber, 1/2 core) as needed. 【Suitable for Harsh Environment】The Ethernet switch has industrial 6KV lighting protection and can work at wide range temperature -40°C to 75°C (-40°F to 167°F) by Using industrial grade components and aluminum housing. 【! NOTE !】It Only support Non-PoE devices. If you don't need the switch to provide extra power to your device, this type is a good choice.
