自光通信问世以来,经历了研究探索、实用化、推广应用、快速发展等时期,直至2001年,达到急剧发展的高潮。随着世界经济的滑坡,通信行业的不景气,使光通信也进入了寒冷的冬天。实际上,即使在经济低迷的时期,光通信的技术依然没有停止发展,而且出现了不少继续将光通信推向前进的新亮点。从技术和应用的角度,简要介绍一些光通信的新技术。
Since the advent of optical communications, it has gone through periods of research, exploration, practicality, promotion and application, and rapid development. Up to 2001, the climax of rapid development has been reached. With the global economic downturn, the downturn in the telecommunications industry, optical communications also entered the cold winter. In fact, even in the economic downturn, the technology of optical communications has not stopped its development and many new bright spots continue to push optical communications forward. From a technical and application perspective, briefly introduce some of the new technologies for optical communications.
