EL1500U - Nitek


The EL1500U is a system for extending Ethernet & PoE.

The EL1500U can be used on new or existing cable and is designed to greatly extend the distance to which IP devices and network devices can operate. In addition to network communication the EL1500U is ideal for PoE applications. It allows all power to flow from the head end for most devices applications. In unique cases where high power PoE is needed it can inject up to 25 watts of power at the transmitter end.

Product Description

The Nitek Etherstretch™ Model EL1500U IP video network extender-PoE Inserter-Injector can quickly turn any ordinary 4 pair category network cable into a high speed network communication & PoE path. When operating over a 4 pair category network cable, distances of up to 600 meters (1968 feet) can be achieved. The EL1500U IP video network extender system consists of a Transmitter and a Receiver set, which requires very little installation time and absolutely no set up or configuration. The Transmitter and Receiver are transparent to the network and have no IP or MAC addressing. Simply connect your network devices to the network ports of the Transmitter and Receiver along with existing cabling and the system begins communicating. LED indicators show the status of network communication and PoE power.
When connected to a PoE switch, power from the switch is used as the power source for the connected EL1500U Receiver.

In applications where network switches are not PoE capable, an optional power source (IP1054 sold separately) can be used to insert power to the EL1500U Receiver.
The power is sent from the Receiver over a 4 pair category cable to the Transmitter. The Transmitter uses PoE as its power source and powers the connected PoE network device as well. The EL1500U UTP network extender extends network communications to overcome cable distance limitations offering connections to devices in locations traditional networking does not allow.
