PROJECT TITLE :
Raman Crosstalk Suppression in NG-PON2 Using Optimized Spectral Shaping
In this paper, we gift an innovative proposal to mitigate the impact of Raman crosstalk within the interaction between NG-PON2 TWDM-PON channels and legacy RF-video by electrical spectral shaping on the TWDM NRZ knowledge stream obtained through electrical FIR filtering. We notice an analytical and closed kind resolution on FIR filter faucets that, for a given target spectral shaping, offers the absolute minimum quantity of intersymbol interference on the TWDM information. Then, we propose techniques to implement these FIR filters with cheap system complexity. We found that our proposed technique is applicable to all categories (up to E2 PON, +11 dBm transmitted downstream power) with less than 0.5 dB power penalty on TWDM channels even in the worst-case state of affairs of RF-video still based mostly on analog channels on the lower half of the spectrum.
