多年来,中国出现了多家运营商共同发展网络事业的格局,在干线传输上不管是广电、联通、电信、移动等网络运营单位都是采用了直埋或架空光缆传输,由于各运营单位建设光缆干线,几乎都是在同一路由建设,无形中出现了在乡间农田光缆干线标桩林立、杆路林立的现象。在运行维护中,各自为政,都要投入大量人力、物力、财力进行维护管理,本人作为行业中的一员,感到在“三网融合”的大环境下,实施光缆干线的融合更具有现实意义。
Over the years, many carriers in China appeared to jointly develop their network businesses. Regardless of radio and television, China Unicom, China Telecom, China Mobile and other network operators all use direct-buried or overhead optical cable transmission over trunk lines, the construction of various operating units Fiber optic cable lines, almost all in the same route construction, virtually appeared in the rural areas of fiber optic cable trunk everywhere, the pole lined phenomenon. In operation and maintenance, their own way, they must invest a lot of manpower, material and financial resources for maintenance and management. As a member of the industry, I feel that it is more realistic to implement the convergence of optical fiber cables under the environment of “triple play” significance.
