摘要 介绍了光纤传输数字电视的意义、电视信号分量数字化的标准和优点。利用自行研制的270Mb/s光发射机和光接收机,建立了分量数字电视信号的光纤传输系统,直接传输了100km光纤,系统传输无误码,传输后图像质量不变。光接收机灵敏度达-29.24dBm,动态范围为13.5dB。无压缩电视图像的传输对于远程医疗和演播室间转输节目等有非常实际的意义。 In this peper, the importance and advantage of optical fiber transmisson of dgitized TV signals arepresented.The standsards of Video/Andio digitization are introduced. Using the 270 Mb/s opticaltransmitter and optical receiver made by the authors, a transmission system for component digitized TVsignals is built up, and its image quality of component digitized TV is not changed through 100km opticalfiber. Optical receiver has a sensitivity of --29. 24 dBm. The transmission technology of non-compresseddigital TV is very useful in the area of remote medical treatment the program exchange between studios.
