为了成本和设计的简单性，已经提出了各种光网络体系结构，其中从光线路终端到光联网单元的下行业务由1550 nm窗口中的载波传输，而上行业务由1300 nm窗口中的载波传输。新一代多模光纤(MMF)的设计就是为了适应这一要求，并解决与光纤耦合相关的技术挑战。通过限制光纤输入和输出的模数，使用现成的单模收发器，在1公里宽波长窗口多模光纤上实现了单波长40Gbit/S数据传输，而功率损失仅为1.5dB。随着波分复用器和偏振复用器等传统单模光纤技术的发展，这种新型MMF的容量有望增加。
For cost and design simplicity, various optical network architectures have been proposed in which downstream traffic from the optical line terminal to the optical networking unit is transmitted by carriers in the 1550 nm window, and upstream traffic by those in the 1300 nm window. A new generation of multimode fiber (MMF) has been designed to accommodate this requirement and to address technical challenges associated with fiber coupling. By restricting the number of modes at both fiber input and output, using off-the-shelf single-mode transceivers, single-wavelength 40 Gbit/s data transmission over a 1 km broad wavelength window multimode fiber has been demonstrated with only a 1.5 dB power penalty. The capacity in this new class of MMF is expected to increase with conventional technologies in single-mode fiber such as wavelength-division multiplexing and polarization multiplexing.
