Leveraging high transmission bandwidth and loss budget provided by high launch power, we experimentally demonstrate 4-lambda 224-Gbps 32-CAP 60-km transmission using cost-effective 10-GHz-class EAM/PIN, supporting > 3-Gbps/ONU for a 64-ONU LR-PON, without inline and pre-amplifier.

We successfully transmit a 112-Gbps PAM-4 signal over 200-m OM4 fiber using 850-nm VCSEL and Volterra filter. Adopting l(1)-regularization can reduce 93% of computation complexity of Volterra filter at the KP4 FEC limit.

We have designed a novel convolutional neural network based nonlinear classifier that outperforms traditional Volterra nonlinear equalizers. A BER of 3.50 x 10(-6) is obtained for a 112-Gbps PAM4 EML-based optical link over 40-km SMF transmission.
High-Capacity Carrierless Amplitude and Phase Modulation for WDM Long-Reach PON Featuring High Loss Budget

This paper utilizes spectrally efficient carrierless amplitude and phase (CAP) modulation and four wavelength division multiplexing channels in formulation of a high-capacity transmission system. The dispersion and loss associated with a single-mode fiber of 60 km can result in severe power fading and insufficient loss budget, respectively. This study employed high launch power to overcome these issues and thereby achieve long-reach transmission without the need for dispersion compensation or an optical inline amplifier. Modified Volterra filtering is used to deal with the linear and nonlinear distortions within the system. This allowed for the inclusion of cost-effective 10-GHz-class electro-absorption modulators and p-i-n detectors for 4-lambda 224-Gb/s 32-CAP 60-km transmission with a loss budget of 26 dB/channel. The proposed system provides support for the 64 optical network units (ONUs) with downstream transmission of > 3 Gb/s/ONU for future long-reach passive optical networks. We also examined the transmission performance of each channel under various launch powers. Increasing launch power from 9 to 18 dBm/channel increases the loss budget by 9 dB and expands the total capacity by 42%.
