Description
Technical field
The extension technical field of HD video is the utility model is related to, especially a kind of DVI signals single-core fiber transmitter.
Background technology
DVI（Digital Visual Interface, digital visual interface）It is current most common high-definition digital video
One of interface, mainly it is made up of four groups of TMDS data channel and one group of DDC passage.TMDS passages are four groups of high-speed differential signals,
Prevailing transmission vision signal（If HDMI, also comprising audio signal）.DDC passages are DDC, aobvious for reading
Show the EDID of equipment（Extended Display Identification Data, extending display identification data）, EDID includes
Show the important informations such as resolution ratio, the audio of display.When source equipment reads by DDC passages the EDID of display device,
Just use TMDS passages by audio video transmission to display end.DVI and HDMI due to transmission be all no compression high-definition video signal,
Its bandwidth is very high, high bandwidth can perfect high definition display effect, but greatly limit the transmission distance of signal again simultaneously
From, it is however generally that, it can only transmit 7 meters or so using common cable.Network cable transmission scheme can transmit 100 meters or so, and
It is easy to cable wiring manufacture, but signal may be by external electromagnetic interference.If signal source is separated by farther with display device（Such as
Between the outdoor large-size screen monitors of large sized commercial center and the Computer Facilities for being separated by hundreds of meters）Even if network cable transmission scheme can not meet
It is required that.DVI signal single-core fibers transmitter is exactly the product for solving such problem, and transmission range is even thousands of up to hundreds of meters
Rice, is made up of transmitting terminal and receiving terminal.Digital video electric signal is converted into optical signal by transmitting terminal, is transmitted through the fiber to reception
End, then optical signal is recovered to electric signal, using optical fiber transmission with electromagnetism interference and the low characteristic that decays, significantly extend and pass
Defeated distance is to more than hundreds of meters.
Current existing DVI signals single-core fiber transmitter, high definition DVI or HDMI letter can be transmitted by single LC optical fiber

Fine transmitter, transmitting terminal have power lights, EDID indicator lamps and EDID study buttons, receiving terminal to have power lights and connection status instruction
Lamp, these indicator lamps and EDID study buttons are disposed on not on ipsilateral of the transmitting terminal and receiving terminal, therefore, more when having
When individual transmitting terminal or receiving terminal are mounted side by side, part indicator lamp and EDID study buttons easily by other adjacent transmission ends or connect
Receiving end covers, and causes user to be not easy to observe or operate.Existing DVI signals single-core fiber transmitter, transmitting terminal relearn
After display device EDID information, the EDID data of original storage can be substituted, once there is maloperation, it is impossible to Default Value is replied,
This equally makes troubles to installation and debugging.Existing DVI signals single-core fiber transmitter, transmitting terminal and receiving terminal appearance color one
Sample, otherwise it is difficult to distinguish transmitting terminal and receiving terminal, this undoubtedly also makes troubles to in-site installation unless carefully seeing model.
