DOF4 is a DVI uncompressed HD video and analog stereo audio extension system over multimode fiber-optic cable for long distance up to 5,000 feet.

Compact and durable design and low power consumption makes it an ideal solution for connection for high definition video/audio signal of digital displays such as LCD/Plasma displays and projectors.

DOF4's unique circuitry and optic conversion design eliminates the need of a copper connection (CAT-5) between the transmitter and receiver. This pure fiber-optic connection enables electrical noise free and EMI free that is ideal for long distance extension of high definition DVI signal, and stereo analog signal.

Features and Benefits

Noise cancellation and error correction logic enhances DVI video and audio signals over long distance
• Built-in signal repeater to support longer distance between the source (and the DOF4 transmitter) and DOF4 receiver and the display
• Compact and robust module design
• Long distance (up to 5,000 feet at 1080i or lower signal) over cost effective multi-mode fiber-optic cables
• Auto EDID Management - The definition of Auto EDID management is a way of saving EDID of a monitor into EEPROM in the transmitter module. DOF4 transmitter has 14 different pre-programmed EDID data that can be conveniently selected by end-user. User can also emulate/save display's EDID information into the transmitter which enhances reliability and compatibility with various displays
• HDCP (High-bandwidth Digital Content Protection) support
