We clarified the relationship between the extinction ratio of upstream burst signals and Q factor of received signals to evaluate the impact of beat noise caused by residual noise interferences.
Polysilane 1 times 3 optical switch circuits were fabricated based on the thermo-optic effect. The waveguide insertion losses were less than -3.1 dB. Optical switch was performed with supplied power of 100 mW or less. Crosstalk attenuation was measured as less than 8.95 dB [1], [2], [3].
We propose a new optical access network system that can provide different services at the same time. Moreover, we develop and test a prototype of a network interface card for the proposed system
