摘要
光纤在光导纤维内部进行传输信息时,要把电信号转化为光信号。光纤具有很强的抗干扰性、可靠性和保密性等,光纤传输容量大,可以不压缩传输数字电视信号,为广播电视信号传输提供很好的方式。介绍在广播电视领域如何运用光纤通信技术、光纤传输特性实现信号直播、回传。
Fiber in the optical fiber to transmit information within the signal should be transformed into light signals. The fiber has a strong anti-interference, reliability and confidentiality, optical fiber transmission capacity, compression and transmission of digital television signals, radio and television signal transmission good way. This article describes how to use the fiber in the field of radio and television communications technology, optical fiber transmission characteristics of the signal broadcast to return.
