We present the first experimental demonstration of using 2D-TCM-PAM8 for a 50Gb/s PON system based on 10G-class O-band DML. Compared to PAM6, the receiver sensitivity of 2D-TCM-PAM8 is improved by 1.1 dB over 20-km transmission.

Nonlinear distortion can be characterized by the orthogonal component. For coherent optical communication, orthogonalization analysis for acquiring the orthogonal component should consider the type of linear equalizer due to the existence of IQ imbalance.

A marker is usually placed in MCFs to identify each core. That gives geometric polarity on both ends of the MCFs. This paper proposes an MCF link that eliminates complexities of polarity management.

Hollow-core fiber NANF prototypes have recently achieved lower loss and wider bandwidth than SMF. Theory predicts further progress may be possible. We investigate the potential impact of future high-performance NANFs on long-haul optical communication systems.
