Quasi-coherent receivers have been demonstrated as a powerful technology for addressing the requirements of the current optical networks based on 10 Gbps line rate. The quasi-coherent technology also has a promising future in the next generation of optical networks where the line rate scales up to 25 Gbps or 50 Gbps. In this paper, the current 10 Gbps quasi-coherent technology has been summarized, together with the first results at 25 Gbps. In addition, this paper shows the roadmap of the future updates of the quasi-coherent technology addressing the necessities of the future optical networks.
