Media Converters
Fibre-optic media converters (also called fibre-optic links, fibre-optic modems, fibre-optic transmitters/receivers) convert video, sound, data, or control signals (analogue or digital) into optical signals. Fibre-optic media converters consist, as a rule, of two units. The first unit converts the electrical signal into an optical signal and the second unit converts the signal back into an electrical signal.
MUX46R and MUX46T are multiplexes that can transmit several data and video channels in parallel. You need only a standard Single-Mode fibre in order to transmit four video signals and six full-duplex channels (full duplex = transmit/receive simultaneously). These cards are perfect for ROVs (remotely operated vehicles) or other remotely steered vehicles which require a high level of precision and a number of video and data signals.
The standardised PC104 cards can simply be mounted/stacked on each other or on other media converters such as Gigabit Ethernet, USB or HD-SDI.
At present, Princetel is working on a card that will be able to manage Ethernet + HD-SDI. The card is expected to be launched during the fourth quarter of 2011.
