Active Network Extender 500 meter. Only data transmission, NO PoE distribution.


The EL1500CB is another component of the Nitek cutting edge EtherStretch™ line. This Environmentally Hardened Etherstretch™ solution allows for the utilization of existing cable infrastructure to transmit data from IP cameras and other network devices over the wire for distances up to 500 meters or 1640 feet.

The EL1500CB is a system containing a transmitter and a receiver unit that requires very little installation time and absolutely no set up or configuration. The system can quickly turn any ordinary RG59 coax cable into a high speed network communication for distances up to 500 meters or 1640 feet. Each unit requires a separate DC power supply with a range from 9Vdc to 56Vdc.

The EL1500CB is transparent to the network thus requiring no IP and MAC addressing. Simply connect your network devices to the networking ports of the transmitter and receiver along with existing cabling and the system begins communicating. LED indicators show the status and speed of network communications. The ET1500CB and ER1500CB do not require network settings to be changed or adjusted.

Nitek EtherStretch™ EL1500CB extends network communications to overcome cable distance limitations offering connections to devices in locations traditional networking does not allow. The EL1500CB is ideal for retrofitting existing installations. The units are constructed of industrial grade RoHS compliant plated aluminum with a corrosion resistant finish making them very durable.
