Using Single Fiber Technology the DVI-D signal is transmitted over only one multimode 50/125 fiber core. Sources and display devices are galvanically isolated against ground loops and hum effects, and no delay occurs in the signal, the video image is transported without any frame latency. Cross compatibility between Lightware fiber products is ensured thanks to our attentive design. In a standalone application DVI-OPT-TX110 and DVI-OPT-RX110 can work together simply, but with Lightware's hybrid modular matrix concept, it is even possible to connect these extender units directly to the matrix router using an MX-DVI-OPT series input or output board. Galvanic isolation between source and display helps to avoid ground loops and hum effects. No delay occurs in the signal during optical conversion, the video image is transported without any frame latency. Powered from DVI source the DVI-OPT-TX110 transmitter does not need external power adaptor simplifying system installation. Recessed thumbscrews allow easy mounting directly to DVI receptacle by hand, or by using a flat-bladed screwdriver. This is most useful in space constraint applications, where the connectors are too close, and can be reached only from the rear side. Massive solid aluminum casing provides excellent cooling and maximum reliability.
