Ethernet over coaxial cable is a non-modem solution designed for the delivery of full-duplex, synchronous high-speed data over existing coaxial cable. Ethernet over coax provide 100BaseT full wire speed Ethernet and (optional) power over the same coaxial cable.
The adapters convert the symmetrical send/receive Ethernet signals into asymmetrical signals and then combine them to be transported over a single strand of copper. [See .] To compensate for the loss that occurs during conversion, the system re-amplifies the received signal.
Depending on the installed coaxial cable type distances of up to 350m are possible, and up to 700m if a repeater is enployed.
The approach to the delivery of power over the same coaxial cable is fundamentally different in the two systems offered by Omega Cubed.
provides power according to the standard IEEE 802.3af, Class 2 which limits the power to 6.5W per port.
Ethernet and PoE Over Coax Transceivers allow 10/100 BaseT Ethernet and PoE power to be transmitted using coax cable. 48VDC power is delivered to one transceiver, which distributes it to up to four remote transceivers.The Power Sourcing Equipment (PSE) supports Powered Devices (PD's) up to 45 watts. Compatible with IEEE 802.3at or 802.3af. 48VDC power is delivered "always-on" on pins 4&5, 7&8.
