Overview

OT-PLC302POE/OT-PLC302-DC is a reliable way to provide both Ethernet connectivity and power over longer distances—without excessive wiring. By combining network data and power over a single cable (two-wire, twisted pair, telephone, or power lines), it cuts down on hardware costs, reduces installation complexity, and supports seamless, energy-efficient operation in a wide range of environments.


Key Features & Benefits


1. Long-Distance PoE Transmission

● Extend PoE up to 500 meters

● Perfect for remote or sprawling installations that require both data and power over greater distances.


2. Easy Installation

● Mini-sized design for limited spaces.

● Plug-and-play configuration—no additional tweaks needed; simply connect and enjoy transparent data transmission.


3. Advanced OFDM Modulation

● Uses Frequency Division Multiplexing to transmit high-speed network signals and low-frequency power simultaneously on a single line.

● Complies with IEEE1901 and IEEE802.3af/at standards, ensuring stable communication and broad device compatibility.


4. Adaptive PoE Management

● Built-in PoE management chip auto-detects and adjusts power output based on the end-point's requirement.

● Receiver unit supports dual power inputs (DC or PoE port). For DC, choose 48–56 VDC; for PoE, connect via a PoE injector, PoE switch, or PoE NVR.


5. Safety and Reliability

● Power terminal polarity protection to prevent damage caused by reverse polarity connections.

● Standard Phoenix terminals and RJ45 network ports offer straightforward connections.


Ideal Applications

● PoE Video Intercom Systems: Power and data for entry panels or door stations over a single, long-distance cable.

● PoE Cameras: Deploy IP surveillance in distant or hard-to-reach locations without installing new power lines.

● Small-Form-Factor Networking: Perfect for limited-space enclosures where standard PoE equipment won't fit.

● Remote PoE Device Extensions: Extend PoE service for various IP devices—access control, monitoring terminals, or IoT sensors—across extensive properties.
