44 Gb/s PAM-4 Short-Reach Transmission with a Polarization-Independent Surface-Normal Electroabsorption Modulator
10 May 2020
We measure performance of 44 Gb/s (22 GBd) PAM-4 short-reach direct detection links with a polarization-independent surface-normal electro-absorption modulator. Performance below the KP-4 FEC threshold are demonstrated in standard single-mode fiber links with no dispersion compensation for distances up to 18 km.
