PoE Media Converters

FR-POE331

10/100Base-TX (PoE+) to 100Base-SFP Ethernet Media Converter with AC Power Input

Compliant with IEEE 802.3af/at standards, it powers devices such as IP cameras, wireless APs, and VoIP phones with up to 30W of PoE output, eliminating the need for external power sources. This converter supports both Fast Ethernet (10/100Mbps) and Gigabit Ethernet (1000Mbps) speeds, ensuring compatibility with diverse network infrastructures. Key features include Link Fault Pass-Through (LFP) to maintain network integrity by mirroring link statuses and a PD remote reset function via DIP switch for effortless troubleshooting of connected devices. Built with an integrated power supply (100–240V AC) to reduce installation clutter, it operates reliably in 0–50°C environments, making it ideal for demanding commercial applications like surveillance systems, industrial IoT deployments, and enterprise networks.
