We investigate the feasibility of low-cost, compact optical filtering for NG-PON2 based on thermally-tuned thin film filters. By considering several contrasting designs in a comparative assessment of their optical performance, complexity, tuning time and power efficiency, we identify relevant technical tradeoffs towards their optimized and low-cost application in NG-PON2 systems.
