随着光纤通信的飞速发展,人们对信息产业提出更高的要求,不少国家已开始着手研究光缆在宽带用户环路中的应用,以便为用户提供高速、宽带的综合电信服务.光缆在国内迅速成为最重要的有线传输信道,按其结构分为层铰式、骨架式和束管式,纤芯数从几芯至数十芯.为了减少电路阻塞,今后的光纤传输网将逐步采取星形网、环形网以及两网结合的混合网形式,因此电信网对纤芯需求很大,传统的单芯光缆将难以满足通信的实际需要.同时大纤芯数的单芯光缆还存在管道资源利用率低、光纤纤号识别困难和光缆接续时间过长的缺点,针对上述问题,通信部门和光缆制造厂商研制推出了新一代叠带式光缆.
With the rapid development of optical fiber communication, people have put forward higher requirements on the information industry, and many countries have already begun to study the application of optical fiber cables in broadband subscriber loops in order to provide users with high-speed and broadband integrated telecommunication services. Quickly become the most important cable transmission channel, according to the structure is divided into layer hinge, skeleton and beam tube, the number of cores from several core to dozens of cores.In order to reduce the circuit obstruction, the future optical fiber transmission network will gradually take the star Network, ring network and the combination of two networks form a mixed network, so the demand for fiber core telecommunications network is large, the traditional single-core optical cable will be difficult to meet the actual needs of communication. At the same time, a large number of single-core optical fiber cable there are still pipe resources Rate is low, the fiber number identification difficulties and fiber optic connection shortcomings too long, in view of the above problems, the communications sector and fiber optic cable manufacturers to develop a new generation of stacked optical fiber cable.
