Research on application of 200μm outer diameter optical fiber in electric telecommunication network construction

摘要

With the rapid development of the electric telecommunication network, the demand for fiber channels is growing day by day. Increasing the number of optical fiber cores has become an inevitable choice for electric telecommunication network construction. If the number of optical fiber cores is increased only by increasing the outer diameter of the optical unit, the structure, weight, mechanical and electrical properties of OPGW will be changed. Therefore, there are strict restrictions on the outer diameter of the OPGW design. It is a visible solution to use small diameter fiber without increasing the outer diameter of optical cell. In this paper, the feasibility and applicability of 200μm G.657.A1 optical fiber applied to the electric telecommunication network are studied. The cable performance of OPGW made by 200μm G.657.A1 optical fiber and the transmission performance of G.657.A1 optical fiber in 10G / 100G ultra-long-haul transmission systems are tested and analyzed, which provide beneficial support and suggestions for the selection of optical fiber and cable in engineering construction of electric telecommunication.
