对于带宽的要求在高速网络和中枢链路之间造成一个瓶颈。大气激光传输为在人烟稠密地区提供高速通讯。大气传输光通讯正作为开发者试图在大都市解决新一代电讯系统而复活。对带宽需求的增长快于网络基本设施的发展，在业务上高速网络与高速中枢链路之间产生一些瓶颈。光纤可以 The bandwidth requirements create a bottleneck between the high-speed network and the backbone. Atmospheric laser transmission provides high-speed communication in densely populated areas. Atmospheric Transmission Optical Communications is reviving as a developer trying to solve a new generation of telecommunications systems in the metropolis. The demand for bandwidth is growing faster than the growth of network infrastructure, creating some bottlenecks between the high-speed network and high-speed backbone links in the business. Optical fiber can
