The development of OF technology promotes the optical cable structure

     The structure of the optical cable has always evolved with the development of the optical network and the requirements of the use environment. A new generation of all-optical networks requires fiber optic cables to provide wider bandwidth, accommodate more wavelengths, deliver higher speeds, ease of installation and maintenance, and longer life. In recent years, the development of fiber optic cable structures can be summarized into the following features.

     1. The cable structure has a clear choice of fiber type according to the network environment used, such as trunk fiber, metro fiber, access fiber, LAN fiber, etc., which determines the requirements of optical fiber transmission characteristics in a wide range of optical cables. The specific conditions of use are also based on the criteria and indicators of the subdivision.

     2. In addition to considering the environmental conditions of the optical cable, the optical cable structure is more and more related to its construction methods and maintenance methods, and must be considered in a unified manner.

     3. The emergence of new optical cable materials has promoted the improvement of optical cable structure, such as the use of dry water blocking materials, nano materials, flame retardant materials, etc., which has significantly improved the performance of optical cable.

Different occasions and different requirements have led to the development of multiple structures of optical cables, and new optical cable structures and various structures that are continuously improved in existing structures are also emerging.
