很多通信厂商近期都在试验可调谐激光器(tunable lasers)产品,其目标是设计一种调制范围覆盖 DWDM 系统所有信道的激光器,它能够快速切换信道,可迅速从一个波长跳跃到另一个波长,有效解决了单一波长的色光承载信息量溢出的问题,使信息能从距离网络中心较远处传输信号到网络中心。由 DWDM 引发随着对带宽的需求的迅速增加,物理学家提出了一种新的低成本方案,从而不必在地下挖掘电缆沟,放置更多管 Many telecommunications vendors have recently experimented with tunable lasers with the goal of designing a laser with a modulation range covering all channels of the DWDM system, which can quickly switch channels and quickly jump from one wavelength to another, effectively Solves the problem that the single-wavelength color light carries the overflow of information, and enables the information to transmit signals from the network center to the network center. Initiated by DWDM As the demand for bandwidth increases rapidly, physicists have come up with a new low-cost solution that eliminates the need to dig the trench in the ground and place more tubes
