With the continuous increase in demand for high-speed, low-energy-consumption networks in the information society, the passive optical local area network (abbreviated as POL or POLAN), as a new generation network architecture, is gradually replacing traditional Ethernet and. With the continuous increase in demand for high-speed, low-energy-consumption networks in the information society, the passive optical local area network (abbreviated as POL or POLAN), as a new generation network architecture, is gradually replacing traditional Ethernet and. Fiber To The Home (FTTH) is already a reality in plenty of real contexts and there has been a further stimulus to the proposal of new solutions and the investigation of new possibilities, in order to optimize network performance and reduce capital and operational expenditure. A complete and. Communication networks are forced to transition to optical access networks in order to boost the information rate of transmission due to huge utilization of internet., 858 Coal Creek Circle, Louisville, CO 80027.
