Optical Line Terminal (OLT) Core of Optical Access Network

The calculations and optimization for OLT splitting ratio are essential in the utilization and efficiency of the optical fibers. The ratio determines the number of ONUs that can be connected to one OLT port. It is derived from factors such as the available optical power budget, the required optical power at each ONU, and the attenuation of the splitters. Optimization is defining the ratio that will give the balance between the served ONUs and the quality of the optical signal. Well optimized ratios can greatly reduce the cost of the network and increase its scalability.
