Abstract
The invention relates to a signal transmission architecture comprising a central processor, a rear panel connector, physical layers, and converters. Signals are sent out by the central processor and then are respectively transmitted to the rear panel connector and the physical layers by the converters. In addition, the signal transmission architecture also includes signal transmission lines that enable the central processor, the rear panel connector, the physical layers, and the converters to be connected together.
Description
[technical field]
The present invention is relevant a kind of signal transmission framework, particularly relates to a kind of signal transmission framework with optical fiber transmission line.
[background technology]
Traditional signal transmission framework comprises central processing unit, back panel connector, physical layer, transducer and cable, and central processing unit, back panel connector, physical layer and transducer link together by described cable.Back panel connector and physical layer is sent to respectively through transducer after described signal is spread out of by central processing unit.Because signal can exist cross-interference issue through cable transmission, so the parallel single-ended signal spread out of by central processing unit is converted to serial differential to signal by described transducer, then is sent to back panel connector and physical layer respectively.If carry out transmission signal in this way, need more cable, cost is higher, and the bandwidth of signal transmission is also lower.
Therefore, the signal transmission framework that a kind of improvement is provided is necessary.
[summary of the invention]
Technical problem to be solved by this invention is to provide the signal transmission framework that a kind of cost is lower, bandwidth is higher.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of signal transmission framework, it comprises central processing unit, back panel connector, physical layer and transducer, back panel connector and physical layer is sent to respectively through transducer after described signal is spread out of by central processing unit, described signal transmission framework also comprises optical fiber transmission line, and central processing unit, back panel connector, physical layer and transducer link together by described optical fiber transmission line.
Relative to prior art, in the utilization of optical fiber transmission line, because optical fiber transmission line does not have the problem of crosstalk when transmission signal, so the signal after transducer conversion can be the single-ended signal of serial, such design, physical transmission line in signal transmission framework decreases, and when transmission path is identical, bandwidth adds.
Other specific features of the present invention are as follows:
The parallel single-ended signal spread out of by central processing unit is converted to the single-ended signal of serial by described transducer, then is sent to back panel connector and physical layer respectively.
Described signal transmission framework also comprises photoelectricity module, and aforementioned transducer is integrated in described photoelectricity module.
The parallel single-ended signal spread out of by central processing unit is converted to the single-ended signal of serial by described photoelectricity module, then is sent to back panel connector and physical layer respectively.
