Abstract

The invention provides a super-strength large core number multi-purpose optical fiber cable which is light in weight, small in external diameter, more in inner core, and capable of meeting different laying environments. A brand novel optical fiber cable is provided for FTTx establishment in our country. The sequentially arranged cross section structure of the super-strength large core number multi-purpose optical fiber cable comprises an outer sheath, a metal hose and a water-blocking tape from outside to inside. An inner cavity of the water-blocking tape is a cabling cable core. The outer side of the cabling cable core is covered with the water-blocking tape. The center of the cabling cable core is provided with a centre reinforcer. The outer ring surface of the centre reinforcer is evenly provided with three or more optical cable units. Each optical cable unit comprises a micro beam tube arranged outside, fiber optical bundles arranged in the center and water-blocking yarns arranged between the inner wall of the micro beam tube and the outer walls of the fiber optical bundles.

Description

technical field [0001] The invention relates to the technical field of optical cable structures, in particular to an ultra-high-strength multi-purpose optical fiber cable with a large number of cores. Background technique [0002] With the development of optical communication, more and more optical cables are used in optical transmission networks, which provides convenience for more efficient signal transmission. But at the same time, with the increase in the amount of optical cable laying, the available space in the area is gradually decreasing. In the future, optical cables that can adapt to various application environments will be favored by various users. At present, the optical cables used in the market are generally limited by the working environment, and the place of use is single. When laying lines, a variety of optical cables are required to be used together. The construction is cumbersome and difficult to maintain. Contents of the invention [0003] In view of t...
