为了使光互联网在速度、可 用带宽及附加业务方面得到巨大改进，必须先做好某些基础工作。这不仅包括大量光纤的安装，还有更多的子系统、交换机以及交叉连接设备，它们真正构成了光网络的神经中心，使基础设备的速度达到１０Ｇｂｐｓ，甚至４０Ｇｂｐｓ。 各厂商正在努力，以
In order for the optical Internet to make huge improvements in speed, available bandwidth and additional services, some basic work needs to be done first. This includes not only the installation of a large number of optical fibers, but also additional subsystems, switches, and cross-connect devices that truly form the nerve center of the optical network, enabling infrastructure speeds of 10Gbps or even 40Gbps. Various manufacturers are working hard to
