CM1-2R2VI-DU dual channel DVI signal fiber optic transmission is a 7-core optical fiber to transmit a way dual channel DVI signals. Module connected via dual fiber optic transmission of digital high-resolution image data, to extend the distance of 500 m, directly connected to PC and monitor, support DVI dual channel. 2 module, a connection PC, connect the monitor to another, by 1.0 meters of DVI dual-link copper. Between the two modules, via the 7 scheduler cord LC fiber optic transmission 7 image data channel (R, G, B, Clk, R2, G2, B2). CM1-2R2VI-DU virtual DDC technology, can support any resolution.
