Abstract

In this paper, we experimentally demonstrated the transmission of 112 Gb/s PAM-4 and PAM-6 signals over standard single-mode fibers for 2 km and 10 km based on a 30GHz-EML. We have used three algorithms, of which MLSE has best BER performance. In consideration of algorithm complexity, FFE is cascaded before MLSE. For PAM-4 signal, the sensitivity is improved by 1 dB when using MLSE compared to FFE.
