光纤通信与电通信相比有着许多比之不及的优越性。因光纤是电的绝缘体,故抗电磁干扰;光纤之间无串音而保密性强,因其频带宽,故通信容量大;光纤重量轻、铺设容易。又因制造光纤的材料一硅在自然界中极为丰富,原材料成本低廉。光纤图象传输系统体现了光纤通信的优越性,它可用于工业监控,电化教学,军用电视,医用电视及广播电视等闭路电视系统作为高质量的声像传输。在一些特殊场合(如易燃易爆等),电缆传输及射频发射无法胜任时,用光纤传输尤为适用。随着国内光通信元器件
Optical fiber communication has many advantages over electric communication. Due to the optical fiber is an electrical insulator, so anti-electromagnetic interference; no crosstalk between the fiber and confidentiality, because of its bandwidth, so the communication capacity; fiber light weight, easy to lay. Because of the optical fiber manufacturing materials, silicon is extremely rich in nature, raw materials, low cost. Optical fiber image transmission system reflects the superiority of optical fiber communication, which can be used for industrial monitoring, electrochemical teaching, military television, medical television and radio and television and other closed-circuit television system as a high-quality audio and video transmission. In some special occasions (such as flammable, etc.), cable transmission and radio frequency transmission can not be qualified, the use of optical fiber transmission is particularly applicable.
