Transmission of ethernet signals and power over coaxial cable

A media converter for transmission of Ethernet signals and electrical power over a coaxial cable, comprising

• a twisted-pair cable interface, the twisted-pair cable interface connectable to a network device by a network cable of twisted pairs for sending and receiving Ethernet signals to and from the network device and for passing electrical power;
• a coaxial cable interface, the coaxial cable interface being connectable to a coaxial cable;
• and
• a signal conversion unit, the signal conversion unit being coupled with the twisted-pair cable interface and the coaxial cable interface, the signal conversion unit being configured to convert Ethernet signals presented at the twisted-pair cable interface for transmission over the coaxial cable, wherein a passive DC circuit path is arranged between the twisted-pair cable interface and the coaxial cable interface for passing electrical power.

A communication method for transmission of Ethernet signals and electrical power over a coaxial cable, comprising the steps of

• connecting a first media converter and a second media converter by a coaxial cable, the first media converter being further connected to a first network device by a network cable of twisted pairs and the second media converter being further connected to a second network device by a network cable of twisted pairs;
• configuring the first media converter and the second media converter to enable transmission of Ethernet signals between the first network device and the second network device over the coaxial cable;
• and
• configuring the first media converter and the second media converter to establish a passive DC circuit path between the first network device and the second network device for delivering electrical power from the first network device to the second network device over the coaxial cable.
