Our Fibre Optic Hybrid DVI-D cables are the perfect solution for easily extending DVI digital signals over incredible distances. Fibre-optic technology allows transmission distances that far exceed the maximum supported by standard copper only cables. These cables feature H-PCF (Hard-Polymer Clad Fibre) glass fibres for sending digital display signals. The Transmitter and Receiver modules are each equipped with standard DVI-D Male connectors for connecting to the source (e.g. DVI graphics card) and the display. The modules are connected together by a fibre and copper solution. Note: This product will work with most graphic cards & displays on the market but certain models do not output power through the DVI port. This will require the use of the optional PSU. The power requirements of the cable are 5V 2A.
