3-port 10/100M PoE Extender

Overview

The ONV-PSE-PD3121L is a 10/100M PoE extender featuring 2×10/100M PoE ports and 1×10/100M uplink PD RJ45 port. Ports 1-2 support IEEE802.3af/at PoE standards with single-port PoE power up to 25W. The extender operates using power from the PoE switch, eliminating the need for an external power supply. Installed at the end of a 100-meter network cable, it extends both network connectivity and PoE power supply by an additional 100 meters at full speed.

As a PoE power supply device, it automatically detects and powers compatible receiving equipment through the network cable. It is ideal for powering PoE terminal devices such as wireless APs, webcams, VoIP phones, video access control systems, and more. This solution addresses high-density PoE power supply requirements and extends twisted-pair PoE transmission up to 200 meters. Suitable for hotels, campuses, factory dormitories, and small-to-medium enterprises seeking cost-effective networking solutions. Plug-and-play operation requires no configuration.
