A paradigm shift in optical communication networks is proposed, with the introduction of a
new ecosystem of devices and components with the capability of transforming current point …

The massive deployment of 5G and beyond will require high capacity and low latency
connectivity services, so network operators will have either to overprovision capacity in their …

Coherent optical systems for short-reach links have seen a boost in their popularity with the
standardization of 400ZR. These systems need to be cost and power-efficient, while coping …

We experimentally investigated a pilot-aided digital signal processing (DSP) chain in
combination with high-order geometric constellation shaping to increase the achievable …

A nonlinearity-tolerant constant composition distribution matching (CCDM) scheme based
on a parallel bisection architecture is proposed. Compared with CCDM based on arithmetic …

Real-time Demonstration of 12-λ×800-Gb/s Single-carrier 90.5-GBd DP-64QAM-PCS
Coherent Transmission over 1 Page 1 978-1-6654-3868-1/21/$31.00 ©2021 IEEE Real-time …

Using coherent optics we demonstrate a seamless fiber-FSO link for DCIs supporting up to 1
Tbps. PCS-based bit-rate adaptation and automatic beam alignment effectively counteract …

Achieving higher spectral efficiency is an efficient approach to address the bandwidth crisis
of optical networks, but it faces significant technical challenges. High-spectral-efficiency non …

First demonstration of a real-time 100.4 GBd PCS-64QAM 2 800G coherent MODEM. A
record transmission distance of 1600 km is achieved for a dual-carrier× 1.6 Tb/s channel …

We report a live-network demonstration of coherent point-to-multipoint technology for mobile
fronthaul applications with total transmission capacity up to 100 Gbps per radio unit and 400 …
