The POT system, one master and one slave units, provide a long-reach Ethernet extension with remote Powerover- Ethernet (PoE) capability over a 2-wire line. Connection with a Class 0 PD device, the distance of two-wire 24AWG cables can be up to 400 meters when using a high power PoE switch. Users may select a fixed data rate for different copper line ranging.The POT master unit is powered by the local PoE Ethernet network, and transmits both the data and power to the remote slave unit over 2-wire cable. The remote unit regenerates the power and provides the PoE capability to power up the remote PD device up to 15 watts when connecting to a high power switch.Equipped with dip switches, the 2-wire line speed can be configured to meet different line gauges and distances. A POT pair offers a cost effective solution for remote power applications such as LAN-to-LAN connectivity, video streaming, FTTB, and MDU/MTU over single twisted line.
