Ethernet extenders support extended Power over Ethernet (PoE) transmission. Certain models function specifically as PoE signal extenders, drawing power directly from the PoE Ethernet cable itself-thereby eliminating the need for an external power supply. These devices effectively overcome the traditional distance limitations of standard Ethernet (100 meters) and PoE power transmission (200 meters), extending both data communication and power delivery distances between the PSE (Power Sourcing Equipment) and the PD (Powered Device). Products utilizing VDSL2 technology can extend transmission distances up to 1,400 meters when using 24 AWG cabling; meanwhile, products featuring the latest chipset solutions can achieve maximum transmission distances of up to 3.2 kilometers. Solutions based on VDSL2 technology offer maximum data rates exceeding 100 Mbps, while those utilizing the latest chipset solutions support Gigabit Ethernet ports, with VDSL2 speeds reaching over 120 Mbps.
These products feature an industrial-grade design, supporting wide operating temperature ranges (e.g., -40°C to +75°C, -20°C to +75°C), redundant power inputs (e.g., 12–48 VDC), high ingress protection ratings (e.g., IP30), and flexible mounting options (such as DIN rail or wall mounting) to ensure reliable operation in harsh industrial environments-including factory automation and wastewater treatment facilities. Installation and maintenance are straightforward; devices support the configuration of Central Office (CO) and Customer Premises Equipment (CPE) modes via DIP switches or jumpers, and feature clear LED indicators for status monitoring. Additionally, select models offer a web-based management interface for advanced configuration. These extenders help reduce cabling costs by enabling network expansion over existing cable infrastructure (such as telephone lines or twisted-pair wiring), thereby eliminating the need to lay new cables or undertake costly facility renovations. Furthermore, the devices feature low power consumption; certain embedded models are specifically engineered for energy efficiency, with full-load power consumption remaining below 2.5 W or 3 W.
