The Renkforce RF-6861940 PoE++ over 2Wire Transceiver enables Power over Ethernet Plus Plus (PoE++) functionality over two-wire cabling and supports data transmission at 100 MBit/s with a maximum range of 300 meters. This device provides both overcurrent protection (OCP) and overvoltage protection (OVP) for enhanced network security. It integrates network entry and exit processes as well as security features for reliable operation. The transceiver supports a master-to-multiple-slaves network topology, allowing for cost-effective network installations where multiple devices can be powered and connected through a single master unit. Designed for network infrastructure applications, this colorless transceiver operates with standard PoE++ specifications and delivers both data and power over existing two-wire cabling systems. The device is suitable for extending network connectivity to remote locations while maintaining power supply capability. Its compact design and straightforward installation make it suitable for various network environments that require extended range beyond typical Ethernet limits. The RF-6861940 model represents a practical solution for network expansion projects where traditional four-pair Ethernet cabling is unavailable or impractical, providing both connectivity and power transmission through minimal cabling infrastructure.
