1.0 PRODUCT DESCRIPTION
The 4800 Series is a high performance, yet affordable, Fiber Optic DVI
Extension System that is designed to carry one (1) DVI channel, over
long distances through four (4) multimode fibers.
No user adjustments are required in the 4800 system due to the use of
advanced digital fiber optic transmission technology. This allows for a
quick and easy setup, offering trouble-free operation for many years to
come. The 4800 system transmits R, G, B, clock signals separately
through one individual fiber and can support video resolution up to UXGA
(1600 x 1200).
The 4800 modules transmit 4 channels (R,G,B,Clk) of graphic data over
fiber. The DVI Digital Display Channel (DDC2B) interface is simulated
by programming EDID (Extended Display Identification Data) parameters
into a non-volatile memory device (EEPROM) located in the TX
(transmitter) module of the 4800 instead of directly from the display
peripheral. This saves the deployment of additional external lines. The
EEPROM is factory programmed to match the peripheral’s display mode.
Broadata defines it as “virtual DDC” or vDDC.
