Currently, most operators are developing two separate fiber access networks: FTTH and Mobile, with its own rules of designing, cables dimensioning, redundancy etc. 5G at its later stage of development will enforce the aggregation of these two fiber networks in different. For emerging applications, the convergence of fixed and mobile networks in the access domain based on a common fiber optic infrastructure makes sense from both technological and economic viewpoints. But what requirements do future fiber optic networks as key enabler for the digital society need to. Fibre is a fundamental, structural part of both 5G mobile and fixed access networks and there is a significant market opportunity to converge and share infrastructure. Fonseca, "Fixed and Mobile Convergence: Which Role for Optical. This structural convergence is being triggered by different architecture trends, e. COMBO European project is studying.
