This DVIGear DVI-7313 4K Fiber Optic Extenders, 1x LC are high performance 4K Optical Extenders that transmit high resolution DVI / HDMI signals over extreme distances using a single fiber optic cable. These extenders support HDMI v1.4 (non-HDCP) signals with resolutions up to 4K (4096x2160 / 30p) over cable distances up to 1640 ft. (DVI-7313) and up to 1.2 miles (DVI-7314). Each extender set consists of an optical transmitter module that converts the DVI / HDMI signals into light pulses for transmission over a single strand of optical fiber cable. An optical receiver module converts the light pulses back to a DVI / HDMI signal for display on a monitor or projector. The transmitter unit includes an internal EDID memory that can acquire and store the EDID from any display. The DVI-7313 supports Multi-Mode optical fiber, while the DVI-7314 supports both Multi-Mode and Single-Mode fiber optic cable. These features make the DVI-7313 and DVI-7314 the ideal future-proof choices for systems designers and integrators who need to transmit high resolution DVI / HDMI signals over extreme distances.
