光纤(Optical fiber)又称光导纤维,它是一种传输光波的介质波导,它是一种由折射率较高的玻璃棒外加折射率较低的玻璃套管在熔融状态下拉成像头发丝一样细的玻璃纤维。由于光纤具有的径细、量轻、透光性好和韧性好,以及抗电磁干扰、抗腐蚀、防燃、防爆、信息容量大、并行无串扰等一系列优异的特性,使依靠光纤技术的光纤通信技术得到迅猛发展,成为未来信息社会和电力网主要传输工具。本文以国网牡丹江水力发电总厂光纤通讯实践操作技术为例,试论光纤通讯技术特点及发展前景。
Optical fiber (optical fiber), also known as optical fiber, which is a dielectric waveguides to transmit light waves, which is a glass rod with a higher refractive index plus a lower refractive index of the glass tube in the molten state pulled like a hair thin Of glass fiber. Due to the optical fiber with a small diameter, light weight, good light transmission and good toughness, as well as anti-electromagnetic interference, corrosion resistance, flame resistance, explosion-proof, large information capacity, parallel crosstalk and a series of excellent features, Optical fiber communication technology has been rapidly developed, becoming the future information society and the main transmission power grid. In this paper, the State Grid Mudanjiang Hydro Power Plant Fiber Optic Communication Practice of technology, for example, discusses the characteristics of optical fiber communication technology and development prospects.
