Systems and methods for measuring and reporting the performance of communications traffic in a Passive Optical Network are disclosed. The cell walls extend along a longitudinal direction of the honeycomb filter to define the cells between the cell walls. The first spatial mode converter conditions a modal profile of the optical signal for propagation through a multi-mode optical fiber. Rotation of the screw translates into rightward or leftward lateral movement of the roller carriage and consequently of the ball receptacle assembly. The architecture provides a balance between fairness and throughput.
