WebWe propose a novel machine learning based equalization algorithm for bandwidth-limited IM-DD PON in C-band. 50Gb/s/λ. PAM4 transmission is demonstrated over 20km SSMF using a 10G-class transmitter with 21dB loss budget without amplification. WebJan 7, 2024 · The chirp behavior is somewhat different for an EML than it is for an isolated electroabsorption modulator. This is because in addition to the dynamic component of the chirp that comes from the EA itself there is also an adiabatic component that is caused by crosstalk between the EA and the DFB laser. WebChirp effect in the SSB system Unlike an MZM, the EML-based intensity modulation induces additional phase modulation because of the bias-dependent chirp [3]. The chirp not only causes an unsymmetrical optical spectrum but also worsens power fading, thereby affecting the requirements of the SSB filter. clean foodie crush
