【摘要】 针对项目研制的实际需要,提出一种利用光纤进行多路低速数据信息与高速视频信息进行混合传输的方案设计,其中时分复用／解复用单元实现了低速数据信息的复用、解复用;高速并／串转换单元实现了数字视频信息的串行化、解串行化;光发射／接收模块实现了信息的电光、光电转换;波分复用／解复用单元实现了1 310nm／1 550nm粗波分复用、解复用,光纤作为信息传输的介质进行高速信息传输。更多还原

【Abstract】 According to the actual need of the item, a kind of mixed transmission of low-speed digital signals and high-speed digital video signals design in use of optical-fiber has been carried out. And in the system the TDM cell realizes the multiplexing and de-multiplexing of the multi-routes of low-speed digitals, the high-speed parallel and serial transmission cell realizes the serial and de-serial of the digital video signals, the WDM cell realizes the 1 310nm/1 550nm wavelength multiplexing and de-multiplexing, the optical-fiber transmits the high-speed optical signals as the transmission media.更多还原
