Multi-Port Ethernet Over Coax Converter

Author: Ethan Ace, Published on Sep 17, 2011

Nitek has announced two new multi-port Ethernet over coax converters, the eight-port EL8500 and sixteen-port EL16500. While some vendors provide power over the coax (such as NVT and Veracity), and others provide a single-space multi-port rackmount device (Vigitron), none have combined all these features to date.

The EL8500/16500 provide power and data to eight or sixteen coax outputs. Cameras at the far end are connected via ET1500C converters, which provide a single RJ45 Ethernet connection with PoE. The units provide full duplex 10/100 Ethernet, and up to 25.5w of PoE, supporting the 802.3af and 802.3at standards. The EL8500/16500 is then uplinked to a standard switch via a Gigabit Ethernet connection, simplifying connectivity. Other multi-port units require an Ethernet connection for each channel, increasing the number of switch ports needed.
