tailieunhanh - OPTICAL FIBER COMMUNICATIONS AND DEVICES

Since 1970, optical fiber and optical communication technologies have been rapidly developing, causing a technology revolution in the communication industries. Due to much lower attenuation and interference, optical fiber has many advantages over existing copper wire in long-distance and high-demand applications. The revolution in communication industries also significantly reduces the prices of optical components and stimulates the development of optical fiber sensors. | OPTICAL FIBER COMMUNICATIONS AND DEVICES Edited by Moh.
