一种极可能标志着新一代光学纤维通讯系统出现的新型光学纤维已有市售。在光纤通讯中,一直存在着一些技术问题,它们限制了高速信号可无干扰地通过光纤的最大长度,而这种新型光学纤维则提供了一种绕过这些技术困难的途径。这样,在光纤通讯系统中,线路中途所需增强信号用的中继器(这是些费事的玩意儿)数目就能相应减少。
A new type of optical fiber that most likely marks the emergence of a new generation of optical fiber communication systems is commercially available. There have been a number of technical problems in fiber optic communications that limit the maximum length of high-speed signals that can be passed without interference through high-speed signals, and this new type of optical fiber provides a way to bypass these technical difficulties. In this way, in optical fiber communication systems, the number of repeaters needed for signal enhancement midway along the line, which is a waste of effort, can be reduced accordingly.
