With the F-M8SD-ET-TXRX by Thor Fiber, you can transport up to eight full rate HD-SDI digital video signals at 1.5Gbps each and Fast Ethernet 10/100mb/s over a single strand of fiber cable up to 80km long. In addition, dual Aux ports provide additional capacity by adding up to 4 analog bi-directional audio, 2 full duplex RS-232/422 links, or 4 contact closure lines per Aux interface. The transmitter inputs support any serial digital signal up to HD-SDI, including SD-SDI or DVB-ASI digital video signals. The F-M8SDI-ET platform delivers more functionality and performance over a single fiber than has ever been available in off the shelf equipment. Each of the 8 HD-SDI signals are fully isolated from each other and operate at a full 1.5 Gbps data rate. Each channel carries its own embedded audio and ancillary data and operates as if it were the only signal on the fiber. The 8 channel platform offers the same 5 pin Aux port custom signal options as the two and four channel units. However, functionality is doubled by providing 2 independent Aux links that can be customized for 4 channel bi-directional or unidirectional audio, 1 or 2 duplex RS-232/422 links, or 4 line contact closure. 10/100 Fast Ethernet is full duplex.
