Nitek's Offshore, Oil & Gas Solution ER8500CB is an active Network 8 port receiver extender, 500 meter PoE over coax NO PoE and power distribution + Switch over COAX


The ER8500CB is another component of Nitek’s cutting edge Etherstretch™ line. Our Etherstretch™ solution allows for the utilization of existing coax cable infrastructure to transmit data from IP cameras and other network devices over the given wire media.
The ER8500CB is a multi-port Ethernet switch for IP video cameras. This Layer 2 switch with a Gigabit LAN connection operates as a standard switch for all Ethernet devices up to 100 meters but when used in conjunction with the ET1500CB transmitter unit (sold separately) operating distances can be extended up to 500 meters (1.640 feet). This makes it ideal for mixed use applications where equipment can be both under 100 meters or up to 500 meters. Being a fully functioning Layer 2 switch it easily integrates into standard network infrastructure.

The ER8500CB receiver and ET1500CB transmitter require very little installation time and absolutely no set up or configuration. The system is completely transparent to the network with no IP or MAC addressing required. Simply connect a network device to the transmitter. LED connectivity indicators on the receiver show the status of network communication. The ER8500CB Etherstretch™ network extender overcomes cable distance limitations inherent in traditional networking topologies and provides a viable alternative to fiber or wireless transmission solutions.
