Mini Industrial 2 Ports Gigabit PoE Media Converter Din Rail Mount Hardened 10/100/1000Mbps Ethernet to SFP Fiber Converter IEEE 802.3bt 90W PoE++ Fiber Switch with 2 RJ45 Port and 2 SFP Port - StarRoute, 2RJ45+2SFP 90w

• 【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. 【48~57V Redundant Power Input】- The PoE++ media converter supports 48~57V 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 PoE++ 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. 【IEEE802.3af/at/bt Active PoE】- The industrial PoE++ switch complies with IEEE802.3af/at/bt standard, automatic detection of powered device. And 10/100/1000Base-T RJ45 port supports both half-duplex and full-duplex mode. 【Industrial Grade Quality】- The fiber media converter adopts industrial grade components and aluminum casing, sturdy and durable, and it can work at wide range temperature -40°C to 75°C which can adapt to harsh environment.
