日本东芝公司已研制出一种波分复用的发送机。这种发送机包含世界首届一指的集成型光导体激光器,它由排列在一块基片上的5只半导体激光器和一只把5种不同波长的光束汇集在一起的波分复用器组成,因此能够在一根光纤上同时输送5种不同的红外信号。使用该装置可以有效地传送大量信息。与此相反,大多数普通的数据传输光纤系统通过一根光纤一次只能发送一种信号,因而使得以输送的信息量受到了限制。
Toshiba Japan has developed a wavelength division multiplexing transmitter. This transmitter contains the world’s first integrated photoconductor laser consisting of five semiconductor lasers arranged on a substrate and a wavelength division multiplexer that brings together five different wavelength beams so that Can transmit 5 different infrared signals on one optical fiber at the same time. Use this device to efficiently deliver large amounts of information. In contrast, most common data transmission optical fiber systems can only send one signal at a time through one optical fiber, thereby limiting the amount of information to be transmitted.
