目前,在美国长途通信网络中,光纤在本地存取和传送区(LATAS)方面的应用主要体现在点对点的干线中,这些干线用来连接电话接线机和遥控电子设备。光纤在这方面的应用优点是价格低廉,不需要很多外部中继电子设备,且具有高比特速率的能力。将来,在点对点传输线的应用方面,将继续用光纤代替金属线传递设备。然而,我们也可以预测今后20年中本地存取和传送方面的系统和技术。今后五年预测预期在今后五年中(到1990年),光纤技
At present, in the United States of America long-distance communication network, the application of optical fiber in the local access and transmission area (LATAS) is mainly reflected in the point-to-point trunk, these trunks are used to connect the telephone wiring machine and the remote control electronic device. The application advantages of the optical fiber in this respect are the low price, do not need a lot of external relay electronic equipment, and have the ability of high bit rate. In the future, in point-to-point transmission line applications, will continue to use fiber instead of metal wire transmission equipment. However, we can also predict systems and technologies for local access and delivery over the next two decades. The forecast for the next five years is expected to be in the next five years (by 1990)
