经过20年来的不断改进,最终实现了T1G,它扩大了T1C载波系统的容量,降低了维护费用,并在环路设备中增加了数字业务潜力.不久前,电信管理部门还热心于在国家的电信网络中发展光纤通信,他们曾玩笑式的预言:总有一天,国家将“取代”那些以铜为资源的网络.无疑,未来将属于光纤通信,但国家的电信公司仍不希望替换数百万电路英里、价值上亿美元的铜心电缆网络.显然,电信公司在新的设备中将沿着两个战略方向来发展
After 20 years of continuous improvement, the T1G was finally realized, expanding the capacity of T1C carrier systems, reducing maintenance costs and adding digital business potential to loop devices. Not long ago, telecom administrations were also enthusiastic about the national The development of fiber-optic communications in telecoms networks has been a joke-like prophecy: one day the country will “replace” those networks that use copper as its source, no doubt the future will belong to optical fiber communications, but national telecoms companies still do not want to replace hundreds Millions of miles of circuit, a multi-billion dollar copper heart cable network. Clearly, telecom companies will grow in two new strategic directions
